The present invention is generally directed to liquid jet cutting systems and, more particularly, to communicating information about liquid jet cutting system components.

Material processing systems such as plasma arc torches and liquid jet systems are widely used in the cutting, digging and/or marking of materials. For example, a liquid jet cutting system is configured to cut a work by rapidly applying a liquid jet such as water to rapidly erode a workpiece at a high speed. Pieces. A liquid jet cutting system typically includes a cutting head including an orifice and a nozzle, a high pressure pump, and a computer numerical controller (CNC). A high pressure pump such as an booster pump can be coupled to the cutting head to pressurize water or another suitable liquid to a high pressure (eg, from 10,000 to 100,000 PSI) and force liquid through a small nozzle and orifice of the cutting head to produce A liquid jet at high speed (eg, up to 2,200 MPH). In some applications, an abrasive is introduced into the liquid jet to cut a harder material. The precise delivery and composition of the liquid jet can be controlled by the CNC.

Generally speaking, a liquid jet cutting system includes a plurality of consumables including a nozzle and an orifice. Individual consumables can be selected for optimal performance (eg, a maximum life) in view of specific processing constraints such as the type of material being cut. Improper consumables installed in a liquid jet cutting system can result in poor cutting quality. In addition, incorrect consumables can reduce consumable life and lead to premature consumable failure. Currently, an operator needs to manually identify the orifices and nozzles used in the cutting head for mounting to a liquid jet cutting system to ensure proper use of the combination.

Even when the correct consumables are installed in a liquid jet cutting system, it may be difficult for an operator to configure and optimize system operating parameters corresponding to the selected consumables. For example, the operator needs to inspect the nozzle to obtain the achieved increase information and manually adjust the slit compensation value accordingly prior to cutting.

Figure 18 is a further illustrative design for housing a cutting head of one of the RFID communication systems.

Figure 19 is an exemplary procedure for operating the liquid jet system of Figure 13.

In some aspects, material processing systems (eg, liquid jet cutting systems and plasma torch systems) can automatically identify system components by processing signals transmitted by one or more signaling devices assigned to the component (eg, Consumable components) and information about components.

In some aspects, a heat treatment torch system (eg, a plasma torch system) can pass a characteristic of a consumable by directing a fluid flow (eg, a coolant liquid flow or a plasma gas flow) The torch element (eg, consumable element) is identified by a change in the flow properties (eg, flow pressure and fluid flow rate) of the fluid flow exiting the feature of the consumable.

1 is a cross-sectional view of one exemplary plasma arc torch 100 including a torch body 102 and a torch tip 104. The torch tip 104 includes a plurality of consumables, such as an electrode 105, a nozzle 110, a fixed cap 115, a swirl ring 120, and a shield 125. The torch body 102, which typically has a cylindrical shape, supports the electrode 105 and the nozzle 110. Nozzle 110 is spaced from electrode 105 and has a central discharge orifice mounted within torch body 102. The swirl ring 120 is mounted to the torch body 102 and has a gas distribution aperture 127 that applies all of the velocity component to the plasma gas flow to cause a radial offset or tilt of the plasma gas flow vortex. A shield 125 that also includes a discharge orifice is connected (eg, screwed) to the fixed cap 115. The fixed cap 115 is fixedly coupled (eg, screwed) to one of the internal fixed caps of the nozzle 110 as shown. In some embodiments, an external fixation cap (not shown) is secured relative to the shield 125. The torch 100 can additionally include electrical connections, passages for cooling, passages for arc control fluids (eg, plasma gases), and a power source. In some embodiments, the consumable includes a system for making a point The fire welding gas passes through one of the nozzles to weld the nozzle.

In operation, the plasma gas flows through a gas inlet tube (not shown) and a gas distribution orifice 127 in the vortex ring 120. From there, the plasma gas flows into a plasma chamber 128 and exits the torch 100 through the nozzle 110 and the discharge orifice of the shield 125. First, a pilot arc is created between the electrode 105 and the nozzle 110. The arc conducts ions through the nozzle to discharge the orifice and shield the gas from the discharge orifice. The arc is then transferred from nozzle 110 to a workpiece (not shown) for heat treating (eg, cutting or welding) the workpiece. It should be noted that the illustrated details of the configuration of the components, the direction of gas and cooling fluid flow, and the electrical connection of the torch 100 can take a variety of forms.

Different operating procedures typically require different shielding and/or plasma gas flow rates, which require different sets of consumables. This has led to a variety of consumables for use in the field. The correct consumables must be used and properly matched to achieve the best cutting performance. Consumable mismatch (eg, using one of the operations for one of the operations at 65 Amps in one of the torches at 105 Amps) can result in poor consumable life and/or poor performance of the plasma arc torch.

2 shows an exemplary communication network 200 of the present invention. Communication network 200 includes one or more signaling devices 202, each of which is assigned to one of the heat treatment torches of one of plasma arc torches 100 of FIG. An exemplary consumable includes electrode 105, nozzle 110, fixed cap 115, swirl ring 120, and shield 125. In some embodiments, a signaling device 202 is configured to transmit an electrically writable device in the form of one or more signals relating to a consumable. For example, signaling device 202 can be a radio frequency identification (RFID) tag or card, a bar code tag or tag, an integrated circuit (IC) board, or the like. In some embodiments, a signaling device 202 is used to detect one of the consumables' physical characteristics and to transmit one of the detected information (eg, a sensor) in one or more signal forms. The communication network 200 also includes at least one receiver 204 for (i) receiving signals transmitted by the signaling device 202, (ii) extracting information communicated by the signals, and (iii) providing the extracted data to a process The unit 206 is used for analysis and further action. The processor 206 can be a digital signal processor (DSP), a microprocessor, a microcontroller, a computer, a computer numerical controller (CNC) machine tool, and can be programmed Logic controller (PLC), application specific integrated circuit (ASIC) or the like.

In some embodiments, each of the signaling devices 202 is encoded using information regarding the consumables to which the signaling device 202 is assigned. The encoded information may be general or fixed information such as the name of the consumable, the trademark, the manufacturer, the serial number and/or the type. The encoded information, for example, can include a model to generally indicate that the consumable is a nozzle. In some embodiments, the encoded information such as the metal composition of the consumable, the weight of the consumable, the date, time and/or location at which the consumable was made, the person responsible for the consumable, and the like is unique to the consumable. As an example, the encoded information may provide a unique serial number for each of the manufactured torch elements to distinguish, for example, nozzle type A, serial number #1, and nozzle type A, serial number #2.

In some embodiments, the information is encoded to a signaling device 202 when the corresponding consumable is manufactured. Information may also be encoded into a signaling device 202 during the life of the consumable, such as after each consumable is used. This information may include the date, time and location of consumable use, any anomalies detected during use, and/or consumable conditions after use, such that a record may be established to predict one of the failure events associated with the consumable or End of life event.

The information encoded to a signaling device 202 can also specify operational parameters. For example, for one of the signaling devices 202 associated with the shield 125, the data encoded to the signaling device 202 may indicate the type of shielding gas and/or the appropriate gas flow rate for the shield 125. In some embodiments, the encoded material of a signaling device 202 provides information about other related components of the torch. For example, the encoded data can identify other torch elements that are compatible with the assigned consumables, assisting in the installation of the entire consumable set in an air torch to achieve certain performance metrics.

In some embodiments, a signaling device 202 includes information regarding the constrainable entity characteristics of the corresponding consumables independent of one of the consumables. Examples of detectable physical properties of consumables include magnetic properties, surface reflectance, density, acoustic properties, and other tangible features of consumables measured by one of the detectors mounted in the torch. Therefore, it can be detected independently of one of the consumables Examples of consumables data for physical characteristics may include consumable name, type, manufacturer, date of manufacture, manufacturing location, serial number, or other non-tangible features of a consumable. In some embodiments, the signaling device 202 stores pre-collection information containing consumables of physical characteristics before it is installed into the torch, but the signaling device 202 is not configured to actively measure or detect physical characteristics. However, signaling device 202 can store physical characteristics regarding the consumption or detection of consumables by another device, such as by a sensor. In general, the signaling device 202 is primarily used for data storage purposes.

In some embodiments, the signaling device 202 is located inside the torch 100 or on the torch 100. For example, the signaling device 202 can be attached to the surface of one of the consumables that is ultimately mounted within the interior of the torch tip 104. Signaling device 202 may also be attached to one of the internal components of torch 100 other than the assigned consumable. For example, although a signaling device 202 is assigned to store information about the electrodes 105, the signaling device 202 can be attached to one surface of the stationary cap 115. In some embodiments, the signaling device 202 is coupled to an external source that is non-physically associated with the torch 100. For example, the signaling device 202 can be attached to one of the consumables for storage of consumables and once installed in the torch 100. If a signaling device 202 is located inside the torch 100, the selectable signaling device 202 is attached to its surface to reduce or otherwise minimize thermal exposure during operation of the torch 100. For example, the signaling device 202 can be located adjacent a cooling mechanism, away from the plasma arc, and/or in one of the o-ring passages of the torch 100 to reduce or minimize thermal exposure. Additionally, signaling device 202 can be coated with a thermal protective material to reduce the likelihood that the device will overheat during torch operation. In general, signaling device 202 can be positioned, such as by another torch element, to minimize exposure to thermal energy, radiation, damage to gases (eg, ozone), and/or high frequency energy.

In some embodiments, a signaling device 202 is designed to be durable, i.e., functioning, during and after one or more torch ignitions. In some embodiments, a signaling device 202 can be discarded after each torch is used or after several uses. In some embodiments, a signal Device 202 can be written once (for example) to encode information about the consumable when initially producing a consumable. In some embodiments, a signaling device 202 can be written multiple times, such as multiple times throughout the life of the corresponding consumable.

In communication network 200, signaling device 202 can wirelessly transmit its stored information to receiver 204 in the form of one or more signals. Receiver 204 is adapted to process the signals to extract relevant information about the consumables and forward the data to processor 206 for analysis. In some embodiments, the receiver 204 is located in the plasma arc torch 100 or on the plasma arc torch 100. For example, the receiver 204 can be located in the torch body 102. In some embodiments, the receiver 204 is at one location external to the torch 100, such as attached to a power module, a gas console, the processor 206, and the like.

In some embodiments, at least one of the signaling devices 202 is an RFID tag and the receiver 204 is used to interrogate one of the RFID tag readers. In such embodiments, the RFID tag includes a microchip for storing information and an antenna for receiving and transmitting RF signals. The reader may include (1) an element for transmitting an RF signal to the RFID tag to interrogate the tag and (2) a component for decoding the response prior to forwarding the response by the RFID tag to the processor 206. . RFID tags can be active or passive. An active RFID tag includes a battery to generate a stronger electromagnetic return signal to the reader, thereby increasing the possible transmission distance between the RFID tag and the reader. The distance between an RFID tag and a reader can range from less than one inch to 100 feet or more, depending on the type of material through which the electrical output, the used radio frequency, and the RF signal need to travel. In one example, the distance between an RFID tag and one of the antennas of a corresponding reader can be about 2 to 4 cm. A reader antenna and remaining reader elements need not be in the same package. For example, the reader antenna can be located on the torch body 102 or inside the torch body 102 while the remaining reader elements are external to the torch 100. The use of an RFID tag is advantageous because it does not require direct contact with the reader (e.g., via wires) or direct line of sight (e.g., via optical signals) and is well suited for use in harsh environments.

In some embodiments, a signaling device 202 is configured to detect at least one physical tag of the consumable for uniquely identifying the consumable or individually identifying one of the detectors (eg, a sensor) by its type. An entity tag can be changed, for example, by one of the consumables. As shown in FIG. 3, the identification of a consumable is achieved by changing the geometry of the consumable such that when it is installed in the torch 100 it affects a wall adjacent the coolant passage 402, which in turn changes the flow through it. The rate of a coolant. In particular, the altered section of the coolant passage 402 can limit the coolant flow rate. A signaling device 202 can be used to measure pressure changes in accordance with coolant flow rates. Thus, the measured coolant pressure change is identified as one of the consumables. In another example, as shown in FIG. 3, an auxiliary vent line 404 coupled to a valve and a flow meter is attached to the nozzle 110 to identify the nozzle 110. The valve is opened prior to plasma arc ignition and the auxiliary vent line flow rate in accordance with the plasma pressure is measured by a signaling device 202 during the flush cycle. Therefore, the measured flow rate is recognized as one of the nozzles 110. In another example, one or more uniquely sized orifices (not shown) may be drilled into the outer fixed cap to identify the cap once it is installed in the torch 100. The size of each restriction orifice is configured to uniquely affect the pressure of the dual position valve and/or the flow rate of the shielding gas. Thus, such measurements taken by a signaling device 202 in a pre-flow path prior to ignition of the arc are used to identify the external fixed cap.

In yet another example, the shield 125 can be identified by measuring the length of the consumable relative to a reference torch data. In an exemplary measurement procedure, a torch height controller is used to determine the height at which a known torch ignites and begins to cut a workpiece. This height can be used as a reference torch data. Next, after installing an unidentified consumable into the torch, determine the height relative to the reference material. Therefore, a simple calculation involving two heights can be used to determine the relative length of unidentified consumables. In turn, the relative consumable length can be used to identify consumables by, for example, referencing one of the relative consumable lengths associated with the consumable parts.

In some embodiments, a signaling device 202 provides information about corresponding consumables The optical machine represents a bar code. A code can be read by the receiver 204 in the form of a code reader. Generally speaking, a signaling device 202 can communicate in the form of any machine readable signal (including radio signals, optical signals, or other light-based signals (eg, infrared or ultraviolet signals), magnetic signals, pneumatic signals, or hydraulic signals). Information about a consumable item.

In some embodiments, a single signaling device 202 is assigned to each of the consumables of a gas torch to transmit relevant information regarding the corresponding consumables. In some embodiments, two or more signaling devices 202 are assigned to the same consumable to transmit different information about the consumables. For example, a signaling device 202 can transmit information that is unique to the type of consumable (such as model and operational parameters for the type of consumable), while another signaling device 202 can transmit information that is unique to the consumable itself (such as consumption) The weight of the product and the history of use). In some embodiments, signaling device 202 in communication network 200 employs data transmission in different modes. For example, when a signaling device 202 transmits data as an RF signal, the other signaling device 202 transmits the data as an optical signal. In some embodiments, network 200 includes a plurality of receivers 204. Each receiver 204 is configured (eg, tuned) to read signals from one or more of the signaling devices 202 and to transmit the extracted data to the processor 206. In some embodiments, a signal receiver 204 is used to read signals from all of the signal devices 202 in the communication network 200. The processor 206 can therefore process the data associated with the plurality of consumables simultaneously.

4 is an exemplary heat treatment system 300 for controlling the operation of a heat treatment torch such as the plasma arc torch 100 of FIG. 1 using the communication network of FIG. The plasma arc torch 100 can include one or more consumables including a nozzle 110, an electrode 105, a shield 125, an inner stationary cap 115, and an outer stationary cap 302. At least one signaling device 202 is assigned to at least one of the consumables for transmitting information regarding the corresponding consumables to the processor 206 via the receiver 204. System 300 also includes a power source 304 for providing the current necessary to generate a plasma arc in the torch 100. The data collected by the self-signaling device 202 for the respective consumables can be used by the processor 206 to control and optimize the plasma power source 304, motor, and driver. 306. Operation of at least one of the gas console 308, the height controller 310, and the nest software 312.

The processor 206 can be located inside or outside of the plasma arc torch 100. In some embodiments, processor 206 is housed in power source 304. In some embodiments, each of the plasma power source 304, the motor and driver 306, the gas console 308, the height controller 310, and the nest software 312 houses at least one processor for processing data from the signaling device 202 to control the respective The function of module 304, 306, 308 or 310.

Based on the information gathered from the signaling device 202, the processor 206 can adjust many of the plasma system functions simultaneously or nearly simultaneously and immediately or near. Such system functions include, but are not limited to, startup sequences, CNC interface functions, gas and operating parameters, and shutdown sequences. In some embodiments, processor 206 uses consumable information to automatically set various parameters of system 300. In some embodiments, the processor 206 uses consumable information to confirm whether certain preset parameters of the system 300 are compatible with consumables within the torch 100. As an example, based on the collected information regarding the plurality of consumables of the torch 100, the processor 206 can control and confirm one or more of the following system components: (i) a power source for regulating power to the torch 100 The setting of 304, (ii) the setting of the nest software 312 for processing a workpiece, (iii) the setting of the gas console 308 for controlling the shielding and/or plasma gas supplied to the torch 100, (iv) The setting of the height controller 310 for adjusting the height between the torch 100 and the workpiece, and (v) the setting of various motors and drivers 306.

In some embodiments, based on data collected from one or more signaling devices 202, processor 206 interacts with nest software 312 to automatically select one of the parameters set for processing a workpiece, such as cutting speed, direction. , path, nested sequence, etc. The cutting program may also define the gas type, gas pressure and/or flow setting and altitude control settings for the torch due to the collected consumable data. Traditionally, when assembling a set of consumables into an airgun, an operator needs to supply information by including the type and thickness of the processed workpiece material, the type of gas used, and the rated current of the consumable group. To software The nest software 312 is manually configured to establish a cutting program for the torch. In particular, the operator needs to manually input the rated current of the consumable group into the processor 206. In the present invention, since the rated current information about the respective consumables is stored in the at least one signaling device 202, the processor 206 can electronically collect the information from the one or more signaling devices 202 and automatically determine the appropriate current setting without the user. Input.

In some embodiments, based on the collected consumable data, the processor 206 is self-occupied by considering consumables data from the signaling device 202 and user input operating parameters including the characteristics of the cut workpiece and the shape to be cut. The set of software 312 selects an appropriate cutting program. For example, an operator may first send a generic program file to the nest software 312. The general program file specifies the variable cutting speed, gas flow, slit compensation, torch height, etc., as the different consumable parts change for each workpiece thickness. Thus, after identifying the consumables using signaling device 202, processor 206 interacts with the general program file to configure one of the torch cutting programs. In some embodiments, after establishing a cutting program, the processor 206 uses the consumable data collected from the signaling device 202 to confirm whether the correct consumables for the program are properly installed into the torch. Alternatively, the processor 206 can instruct the nest software 312 to automatically set or correct the parameters of the program to improve compatibility with the consumables loaded in the torch. For example, one of the 400 A currents requires a larger cut and lead-in line than one that requires 130 A current. Thus, if a 400A consumable is loaded into an airfoil, the nest software 312 can select fewer parts to fit on one of the nests of the program.

In some embodiments, based on data collected from one or more signaling devices 202, the processor 206 can manipulate a gas console 308 to control the plasma and shielding gas to the torch 100 by confirming and adjusting the gas console settings. The flow. The gas console 308 houses solenoid valves, flow meters, pressure gauges, and switches for plasma and shielded gas flow control. For example, a flow meter is used to set the pre-flow rate and cutting flow rate for the plasma and shielding gas. The gas console 308 can also have a multi-inlet gas supply region in which the plasma and shielding gas are connected. A two-state thixotropic switch can be used to select the desired gas. Gas pressure sensor Monitor plasma and shield gas. In one example, one of the signaling devices 202 associated with the shield 125 of the plasma arc torch 100 can store information regarding the type and composition of one or more shielding gases suitable for use with the shield 125 and shielding gas. Optimal flow rate setting. Based on this information, the processor 206 can interact with the gas console 308 to provide the appropriate shielding gas to the plasma arc torch 100 at an optimum flow rate.

In some embodiments, processor 206 operates a torch height controller 310 that sets the height of the torch 100 relative to the workpiece based on data collected from one or more signaling devices 202. The torch height controller 310 can include a control module to control an arc voltage during the cutting to maintain a predetermined arc voltage value by adjusting the gap (ie, the distance between the torch 100 and the workpiece). The torch height controller 310 can also include an external control module to control the gap. The torch height controller 310 can further include controlling, by the control module, a lift through a motor or driver 306 to slide the torch 100 in a vertical direction relative to one of the workpieces to maintain a desired voltage during cutting. In one example, based on data collected from a torch consumable, the torch height controller 310 can automatically determine the height to position the torch relative to the top of a workpiece. Therefore, the torch height controller 310 does not need to perform a height sensing to set an appropriate penetration height and cutting height before starting the arc voltage control. In some embodiments, based on data collected from one or more signaling devices 202, processor 206 operates motor and driver 306 to laterally move torch 100 relative to the surface of the workpiece. The processor 206 can also manipulate the height controller 310 to move the torch 100 vertically relative to the surface of the workpiece.

In some embodiments, the processor 206 is configured to determine if the consumables installed in the torch 100 do not match each other, are incompatible with the thermal processing system 300, or have other pre-selected operational parameters input by an operator. Inconsistent prevents the heat treatment system 300 from starting an operation on the workpiece. If such a determination is made, the processor 206 can trigger an indication to the operator that one or more of the connected consumables are not supported and should replace the consumable or should modify the operator input one of the audio or visual alerts. Additionally, if an alert is triggered, the processor 206 can prevent the start of an operation. For example, if it is communicated by a signaling device 202 assigned to one of the shields 125 The current setting to the shield 125 to the processor 206 is different than the current setting communicated to the nozzle 110 of the processor 206 by a different or identical signaling device 202 of the nozzle 110, and the processor 206 can stop the torch operation.

In some embodiments, the processor 206 is configured to prevent the heat treatment system 300 from operating if it determines that at least one of the consumables installed in the torch 100 is not manufactured or otherwise supported by the accepted manufacturer. For example, if processor 206 cannot identify the manufacturer identification, serial number, and/or part number communicated by a signaling device of a consumable, processor 206 may cease the torch operation. Thus, heat treatment system 300 can be used to detect and prevent the use of inferior or counterfeit consumables.

In some embodiments, processor 206 recommends one or more remedial actions to the operator to resolve the alert context. For example, the processor 206 may suggest installing one or more consumables in the torch 100 to avoid potential mismatch with other components of the thermal processing system 300. The processor 206 can suggest a suitable type of workpiece for processing based on the rating of the installed consumable set. The processor 206 can recommend a cutting sequence that matches the settings of the installed consumables with the settings provided by the operator.

In general, the signaling device 202 can store information about the components of the torch other than consumables. For example, signaling device 204 can store information about torch body 102 or about one or more leads. Thus, as will be fully appreciated by those skilled in the art, the exemplary communication network 200 of FIG. 2 and the configuration of FIG. 3 can be readily adapted to store information about any of the torch elements.

5 is another exemplary heat treatment system 500 that uses the communication network 200 of FIG. 2 to change, control, or otherwise affect the operation of a heat treatment torch such as the plasma arc torch 100 of FIG. The heat treatment system 500 includes a computerized numerical controller (CNC) 502, a power source 504, an automatic program controller 508, a torch height controller 512, and a driver system 516, each of which is similar to the processor 206 of the operating system 400. The power source 304, the gas console 308, the height controller 310, and the motor and driver 306. In addition, the heat treatment system 500 package A cutting table 520 is included.

To operate the thermal processing system 500, an operator places a workpiece on the cutting table 520 and mounts the torch 100 into the torch height controller 512 attached to the elevated 522. Drive system 516 and height controller 512 provide relative motion between the tip of the torch and the workpiece, and torch 100 directs the plasma arc along one of the processing paths on the workpiece. In some embodiments, at least one receiver 204 is attached to one of the components of the thermal processing system 500 to receive signals emitted by at least one signaling device 202 associated with one or more consumables of the torch 100. For example, a receiver 204 can be coupled to the overhead 522 to read signals from the torch 100 after the torch 100 is installed into the system 500. Receiver 204 may also be attached to other system components including, for example, CNC 502, height controller 512, driver system 516, or cutting table 520. In some embodiments, the receiver 204 is mounted inside the surface of the torch 100 or on the surface of the torch 100. In some embodiments, a plurality of receivers 204 are distributed throughout system 500 of the flare 100, each receiver 204 being tuned to read information about one or more particular consumables of the flare 100. For example, while a receiver 204 is used to receive data from one of the signal devices 202 assigned to one of the nozzles, the other receiver 204 is configured to self-assign to one of the masked signal devices 202 to read the data. After obtaining information from a signaling device 202, the receiver 204 can transmit information to the CNC 502, which uses the information to configure the thermal processing system 500 for processing.

In some embodiments, different consumables information is used to encode the signaling devices 202 associated with the same (or at least substantially the same) consumables of the two sets of entities and to install the signaling devices 202 into two different torches. For example, even if both nozzles are manufactured to the same design specification, the serial number A can be used to encode one of the nozzles for one torch, and the serial number B can be used to encode another nozzle for the second torch. Signaling device. Install the nozzles into their respective torches. The two torches are mounted to their respective heat treatment systems, and the receivers 204 of each heat treatment system can receive consumable data from the respective torch signal devices 202. In some embodiments, based on different consumables data, even when two torches are consumed When the products are physically identical to each other and all of the external factors are the same (for example, the material type and thickness of the workpiece processed by the two torches are the same), the heat treatment system is adapted to appropriately adjust one or more operating parameters of the system to operate the gas differently torch. For example, based on different consumable data, the consumable data can cause the thermal processing system to interact with the respective nest software 312 to effect different cutting programs for the two torches and/or interact with respective height controllers 512 to set The different heights of the two torches. In general, based on different consumables data, a heat treatment system corresponding to one of the torches can be configured to include features A, B, or C, and one of the other torches can be configured to contain features corresponding to other torches. X, Y or Z. In some embodiments, the same heat treatment system can be configured differently depending on the consumable data encoded in the two torches. Exemplary features that can be customized by a heat treatment system include: plasma gas flow and timing; shielding gas flow and timing; cutting current and timing; arc initiation and timing; torch height above the surface of a workpiece and/or The torch moves parallel to the surface of a workpiece.

In some embodiments, a heat treatment system is adapted to initiate a proprietary program only after determining that information regarding one or more consumables in the torch meets a particular standard, such as manufactured by a particular manufacturer. This information is stored on one or more of the signal devices 202 coupled to the consumable and is accessible by the heat treatment system. Thus, if the consumables are manufactured by a different manufacturer and do not have the correct (or any) information encoded in the signaling device 202, then even the "incorrect" consumables are produced by the manufacturer. The consumables are the same entity and the heat treatment system does not initiate proprietary procedures. In some embodiments, a heat treatment system does not initiate a proprietary procedure when the system does not sense any data from the torch consumables. This can occur, for example, when the consumable is not associated with a signaling device 202 or the signaling device is defective. Therefore, executing a configuration program by a heat treatment system may only involve the system detecting whether a consumable is associated with the correct data and/or alerting the operator if the consumables detect incorrect information or no information. An exemplary alert includes an alert, a visual indicator, or a combination thereof. In addition, the system can respond to the detection of incorrect information or no information from consumables. Prevent the operation of a torch.

6A and 6B are flow diagrams showing an exemplary operation of the communication network 200 of FIG. FIG. 6A illustrates an exemplary procedure for assembling a heat treatment torch to include one or more consumables and signaling devices 202. In particular, in step 602, two consumables are provided, wherein two consumables are manufactured based on the same (or substantially the same) physical specifications. As a result, the two consumables have the same (or substantially the same) physical characteristics. A signaling device 202, such as an RFID tag, can be coupled to each of the two consumables. Each of the signaling devices 202 can be located on the body of the corresponding consumable or in the body of the consumable. In steps 604A and 604B, the signaling device 202 for each consumable is encoded using data that can be used to determine system configuration settings to operate the corresponding torch. For example, data A can be used to encode a consumable and data B can be used to encode another consumable, wherein data A and data B can be used to set one or more operational parameters of the respective thermal processing system to operate the respective torch. In some embodiments, data A and data B contain different serial numbers assigned to respective consumables associated with different values for setting operational parameters of the thermal processing system. Exemplary operational parameters associated with a heat treatment system include a height of the torch above a workpiece, a flow rate of plasma gas through the torch, and a cutting program for processing a workpiece using the torch. In steps 608A and 608B, the various consumables manufactured in step 602 and their respective signaling devices 202 are assembled into an air torch.

6B illustrates an exemplary procedure for configuring two heat treatment systems, such as heat treatment system 400 of FIG. 4 or heat treatment system 500 of FIG. 5, for operation of the two torches of FIG. 6A. In steps 612A and 612B, the torch is mounted to its respective heat treatment system. Referring to the thermal processing system 500, individual torches can be mounted to the elevated 522 above the cutting table 520. In steps 614A and 614B, the receiver 204 of the respective heat treatment system is used to read the consumable data encoded in the signaling device 202 corresponding to the consumable. For example, in step 614A, a receiver 204 can read the material A from the signaling device 202 associated with the consumable of the first torch. In step 614B, another receiver 204 can read the material B from the signal device 202 of the second torch consumable. In step 618A and step 618B, The receiver 204 of the thermal processing system transfers the data to the respective CNCs of the thermal processing system, and the CNCs set and/or adjust certain parameters of the corresponding thermal processing system to operate the corresponding torch based on the received data. In some embodiments, even if the consumables are physically identical to each other, the differences in the encoded data for the two consumables are translated to different values for setting operational parameters of the thermal processing system. In some embodiments, the heat treatment system assigns the same value to the operational parameter despite the difference in the encoded material.

In some embodiments, the method described with reference to FIG. 6B is implemented by a single heat treatment system adapted to operate the operating parameters of the system for operating one or both of the two torches simultaneously or sequentially (ie, one torch at a time).

In addition, it will be fully appreciated by those skilled in the art that the invention described herein can be applied not only to plasma cutting devices, but also to welding type systems and other heat treatment systems. In some embodiments, the invention described herein is configured to operate using a variety of cutting techniques including, but not limited to, plasma arc, laser, oxy-fuel, and/or water jet techniques. For example, signaling device 202 can be coupled to one or more consumables configured to operate using one or more of the cutting techniques. The processor 206, which uses the information transmitted by the signaling device 202, can determine whether the consumables installed in an air torch are compatible with a particular cutting technique. In some embodiments, based on the selected cutting technique and consumable information, the processor 206 can accordingly set or adjust operating parameters such as the height of the cutting head above the workpiece that can vary depending on the cutting technique and consumables.

As an example, it is known to use a water jet system that produces high pressure, high velocity water jets for cutting a variety of materials. Such systems typically concentrate on a small area by pressurizing water or another suitable fluid to a high pressure (e.g., up to 90,000 pounds per square inch or more) and forcing the fluid to pass through a small nozzle orifice at high speed. A large amount of energy works. An abrasive jet is one type of water jet that can include an abrasive material within a fluid jet for cutting a harder material. In some embodiments, the signaling device 202 is attached to a consumable of a water jet system, such as a water jet orifice, a mixing tube for mixing the abrasive particles with the fluid, and/or Or one or more high pressure cylinders, pump seals or valves. A signaling device 202 associated with a water jet orifice can, for example, identify the size of the orifice, the number of hours of tracking operation, and can also indicate other consumables suitable for use with a particular orifice. Identification of a particular consumable combination of a given water jet system can also be performed to confirm compatibility with a given system or to set operating conditions and parameters such as water pressure or abrasive type or amount of abrasive.

In some aspects, a thermal cutting system, such as a plasma arc cutting torch, can include passing a gas through a torch (eg, through a feature of a consumable component) and detecting a flow of gas therein as the gas flows Apparatus and features for detecting or identifying consumable components mounted in the torch by means of a change in the flow of the torch and consumable components. For example, in some embodiments, a gas is directed to flow through features disposed on a consumable (eg, a nozzle or a swirl ring) (eg, including a restriction orifice, a vent, a gas discharge orifice, Flow restricting components of flow distribution channels or other features). Based on the observed changes in one or more fluid flow characteristics (eg, gas pressure or flow rate) upstream and downstream of the feature, the size of the feature can be identified and thus the consumable itself can be identified. As discussed below, a water jet system can also be used to implement the methods described below to identify various components that are installed in the system.

To monitor the flow of gas through a material processing system (eg, a plasma arc torch system or a water jet system), the system can include a gas line (such as a semi-rigid line or a flexible hose). A plurality of gas flow detecting devices, such as valves, pressure detectors, pressure regulators, gas flow meters, and the like, all of which are fluidly connected to each other. Referring to Figure 7, in some embodiments, a fluid (e.g., gas) delivery system 700 for delivering gas to a material processing device (e.g., a gas torch (e.g., a gas torch head) 701 can include a fluid supply (eg, a compressed air tank or air compressor) 702, a supply dual position valve 704, a supply pressure sensor 706, and a supply gas flow detector 708 (as depicted by a dashed box, providing a sense of pressure) The detector 706 and the supply gas flow detector 708 can be a single component (for example, a pressure compensation flowmeter), a supply gas pressure regulator 710, and a double position. A valve pressure sensor 712, typically a venting pressure sensor (eg, a gas plasma plenum pressure sensor) 714, a venting two position valve 716, a venting gas flow detector 718, and a torch venting Gas outlet 720. The gas supply 702 is typically fluidly coupled to one of the torch system control units (eg, a power source) that can accommodate the supply of the two position valve 704, the supply pressure sensor 706, and the supply gas flow detector 708 (or a combined pressure compensation flow meter) .

Supply gas pressure regulator 710 and dual position valve pressure sensor 712 are typically independent of, for example, a control unit disposed on or within one of the torch gas supply leads of the control unit for providing gas and electricity to a gas torch And positioning. In some cases, the supply gas pressure regulator 710 and the dual position valve pressure sensor 712 are disposed adjacent to the torch 701 that is coupled to the lead at one end opposite the control unit (eg, within 10 feet (eg, 6 feet) Inside)). As discussed below, by arranging such elements closer to the torch 701, the gas pressure controlled and monitored within the leads by the supply gas pressure regulator 710 and the two position valve pressure sensor 712 can more closely represent the delivery to the gas. The actual pressure of the torch.

As shown, these various components can be joined to one another by any of a variety of structural and chemically appropriate tubes or hoses. Examples of suitable hoses include flexible hoses (eg, flexible plastic or rubber hoses), rigid tubing (eg, rigid metal, plastic or composite tubing) or one of a flexible layer and a rigid layer A pipe made in combination, such as a flexible hose having a woven outer member (e.g., a braided sheath). Some or all of these components may be in communication (e.g., wireless or wired communication) with a control unit (e.g., a processor within a torch system control unit) for monitoring and controlling the gas delivery system.

Based on the configuration of these various components, the gas flow can exit the torch from one or more different zones. For example, when a gas flow G enters the torch head 701, a gas stream G1 is typically ejected from the torch head (eg, via a nozzle orifice). Gas stream G1 generally comprises a gas that is typically used to generate a plasma stream and process a material. In addition, when the gas flow G enters one of the flow restricting members of one of the vortex rings 727 (shown in the schematic form in FIG. 7), the gas flow G may be divided into a plurality of flow passages to form the gas flow G1 and Second gas Flow G2. Thus, for a torch system having a venting system, a second gas stream G2 can be directed by a vortex ring 727 (or one of the nozzles vents as mentioned below) and based on certain components of the venting system (eg, Whether the venting double position valve 716) is opened or closed and is emitted from the gas torch via the venting system. In particular, in some embodiments, a gas stream G2 exits the torch when the venting two position valve 716 is open. That is, the gas stream G2 can be caused by the flow of gas within the various flow passages and the orifices within the torch head. As schematically illustrated, the gas flow G can enter the torch via a two-position valve hose and be divided into a gas stream G1 and a gas stream G2 within the torch head, and the gas flows through consumable components disposed within the torch (eg, , vortex ring or nozzle). For the sake of simplicity, it is schematically illustrated that the gas within the torch is divided into a gas stream G1 and a gas stream G2 without exhibiting a particular consumable element. Alternatively or additionally, in some cases, gas flow G is delivered from a vortex ring to a nozzle and a first portion (eg, gas stream G1) may be directed to be ejected from the torch in the form of a plasma gas and may be directed A second portion (e.g., gas stream G2) passes through the nozzle through a venting region (as discussed below with respect to Figure 8) to the flow restricting member and through a venting passage to the outside of the lance.

In some embodiments, a system (eg, system 700) for identifying a heat treatment torch such as a nozzle or a swirl ring one of the consumable components comprises: a flow restriction member (eg, a nozzle orifice, a a flow restrictor of one of the nozzles, a vent of a nozzle or a gas distribution orifice of a vortex ring, associated with the consumable and configured to receive a flow of gas therethrough; a first sensor (eg a two-position valve pressure sensor 712) to determine a pressure of gas flow through the flow restricting member at a position upstream of the flow restricting member; a second pressure determining device to establish a position downstream of the self-flow restricting member a pressure at a flow of gas through the flow restricting member; a flow meter (eg, a venting gas flow detector 718) for measuring a flow rate of gas flow through the flow restricting member; and a control unit (eg, , a processor) that uses the first pressure, the second pressure, and the flow rate to identify an operational characteristic of the consumable.

In some cases, the second pressure determining device can include, for example, when the vent valve is closed The fluid that can measure the pressure within the plasma plenum is coupled to one of the torch venting pressure sensors (eg, venting pressure sensor 714). Alternatively or additionally, in some cases, the second pressure determining device includes a venting valve configured to expose a position downstream of the flow restricting member (eg, the flare venting passage) to the atmosphere to set the pressure to one of atmospheric pressure (eg, venting double position valve 716). That is, in some cases, the second pressure is not explicitly measured by one of the components of the gas delivery system, but is set to atmospheric pressure (eg, 0 psig). As discussed below, this configuration may allow for the identification of only one of the pressure sensors to be used when exposing the area downstream of the flow restriction member to atmospheric pressure, for example, by opening the vent valve 716.

Additionally, as described above, in some embodiments, the system can include at least one radio frequency identification (RFID) tag attached to the consumable, in the consumable, or in communication with the consumable for identifying the consumable.

To measure and control the gas pressure within the various gas passages of a gas flare head, the gas passages can be fluidly coupled to a gas flow measurement device (eg, a gas pressure or flow sensor). Alternatively, in some cases, the gas flow measurement device can be disposed within the torch head. Referring to FIG. 8, in some embodiments, a torch 800 includes a consumable (e.g., nozzle) 803 having a flow restriction member (e.g., a nozzle ventilation identification aperture) 805. One of the plasma plenum chambers 802 defined within the nozzle can be fluidly coupled to a pressure sensor (eg, the flare venting pressure sensor 714) such that the gas pressure within the plasma chamber 802 can be monitored and measured. For example, when the fluid is coupled to a nozzle venting passage 806 (which is typically fluidly coupled to a venting pressure sensor 714, a venting two position valve 716, and a venting venting gas flow detector 718), the two-position valve pressure is When the sensor 712 is closed, a pressure plug can be created in the nozzle vent 806 and the plasma plenum chamber 802. Therefore, the common pressure detected by the venting pressure sensor can indicate the pressure in the chamber of the plasma plenum. A gas supply region 804 is typically located at a location upstream of the consumable 803. During use, a gas (eg, a plasma cutting gas) may be delivered from the gas delivery system 700 to the gas through a flow directing passage of the swirl ring. Supply area 804. In the illustrated example, at least a portion of the gas flowing into the plasma chamber of the nozzle 803 and entering the plasma chamber can flow to the nozzle 803 through a nozzle venting region 808 and a venting aperture (identification aperture) 805. Outside. In such embodiments, the venting passage 806 can be considered as one of the regions downstream of the flow restricting member 805.

As discussed herein, the gas flow properties observed at various locations within the gas flow system can be used to identify consumables installed in the torch. For example, a torch gas delivery system (eg, flare gas delivery system 700) can be used to implement one or more plurality of torch consumable component identification methods by manipulating and monitoring gas flow within the flare system.

For example, in some aspects, a gas flow (eg, gas flow G) can be provided to the torch and a vented two position valve can be closed to establish pressure by adjusting one of the gas flows provided to the torch. A predetermined gas pressure in the plasma plenum and the venting passage of the gas torch. With the venting double position valve closed, gas pressure begins to build up in the area of the torch plasma plenum and the vent line so that the gas exits substantially only through the lance discharge orifice (i.e., in the form of gas stream G1). Once a predetermined gas pressure is established within the plasma plenum region and the vent line, the pressure and gas flow rate of the gas flow directed through the consumable can be monitored and measured (eg, the flow rate upstream of the consumable, such as provided to the vortex The flow rate of the ring). The measured gas flow rate and pressure can be compared to known (or expected) corresponding gas flows and pressures for a plurality of different consumables. The type of consumables installed in the torch can be identified based on a comparison with known values as discussed in detail below in the examples below.

In some embodiments, once the predetermined gas pressure within the plasma plenum and the venting passage is established, the venting two position valve can be opened to expose the flow region downstream of the flow restriction (eg, the venting passage line) to atmospheric pressure so that the gas can pass The torch head (gas stream G1) and the gas torch are exhausted by aeration (to form a gas flow G2). The gas flow G1 and the gas flow G2 flowing from the torch can be used to measure the pressure and flow rate of the gas guided to the consumable and the gas flow through the aeration. Similarly, the measured pressure and gas flow values can be compared to typical expected values associated with certain consumables to predict the type of consumables installed in the torch. can The general consumable identification method described above is implemented in any of a variety of configurations.

Referring to Figure 9, in some aspects, an exemplary method (900) for identifying a consumable of a heat treatment torch includes first directing a gas flow through a consumable disposed within the heat treatment torch (e.g., a A nozzle or a swirl ring is associated with one of the flow restricting members (902). For example, in some embodiments, gas is delivered to a torch head from a gas supply (eg, gas supply 702) via a gas delivery system (eg, regulator 710). The gas may be delivered to the torch head and directed through a flow restriction unit such as an orifice associated with the consumable (eg, one of the nozzle discharge orifices (eg, a plasma discharge orifice), a swirl ring One of the gas distribution holes, or another venting or restriction orifice of the consumable). In some embodiments, different flow restriction components can be used to identify different types of consumables. For example, when a nozzle is used, the flow restricting member may include one of the nozzles to identify the vent or the plasma discharge orifice, and when a shield is used, the flow restricting member may include a shielded vent. In some cases, a gas distribution aperture can be used to identify a vortex ring.

In some embodiments, the flow restricting member does not have a hole, such as the absence of a vent on a nozzle. For example, a nozzle may not include an identification vent, such that when a vent valve is opened (it is expected that gas flow begins to flow from the vent of the nozzle and flows out of the venting), the venting flow detector is not detected. Flow to any gas. When the vent valve is opened, a lack of detected venting flow will thus indicate that one of the vents is not installed in the ram.

Next, a first pressure (904) can be determined. For example, one of the pressures of the gas flow at a location upstream of the flow restriction member can be determined. In some embodiments, the venting two position valve 716 can be closed to allow a pressure to build up in the venting region and the plasma plenum, which can also cause the torch to substantially only produce the gas stream G1. With the venting double position valve 716 closed, the first pressure can be manually adjusted, for example, using the pressure regulator 710 to set the pressure in the venting passage and the plasma plenum to a predetermined value. In some cases, the predetermined pressure value may be about 4 psig or another predetermined pressure based on the capabilities of the device. So once A predetermined plasma plenum pressure is established to measure the pressure (eg, the first pressure) of the gas delivered to the torch head. In some cases, once a predetermined plasma plenum pressure is established, the dual position valve pressure sensor 712 is used to determine the pressure of the gas directed to the flow restriction member. Alternatively, in some embodiments, the venting two position valve 716 can be opened to vent a region downstream of the flow restriction (such as downstream of one of the nozzle vents) to atmospheric pressure, and a sensor can be used (eg, a pair The position valve pressure sensor 712) determines (eg, measures) the first pressure upstream.

A second pressure (906) is also determined. In particular, the pressure of the gas passing through the flow restricting member and exiting the torch head can be measured. For example, as discussed above, in some cases, the venting dual position valve can be closed such that a pressure (eg, a second pressure) is created in the venting region and the plasma plenum. In particular, the second pressure can be determined, for example, by adjusting the pressure regulator 710 by manually setting the second downstream pressure (ie, in the non-vented plasma plenum) to a predetermined pressure (eg, 4 psig). . Alternatively, in some embodiments, the downstream pressure (eg, the pressure within the venting zone) is set to another known pressure by, for example, opening the venting two position valve 716 to open the venting passage to the atmosphere ( For example, atmospheric pressure) to determine the second pressure.

In the case where the first pressure and the second pressure are determined, a flow rate of the gas flow through the flow restricting member can be determined (908). For example, in some embodiments, flow detector 708 can be used, for example, to measure the flow rate of a gas provided to the torch. Alternatively or additionally, a flow rate of gas (i.e., gas flow G2) of the gas exiting the torch head by venting may be measured, for example, using a venting flow detector 718.

The consumable (910) can then be identified using the detected first pressure, second pressure, and flow rate. For example, once the gas pressure upstream and downstream of the flow restricting member is determined and the flow rate of the gas exiting the torch through the venting double position valve (ie, gas flow G2) is determined, it can be identified by accessing a lookup table (estimation) ) consumables. In some cases, a lookup table can include a list of one of a plurality of torch consumables by using the description herein. The identification methods are defined by their respective expected flow characteristics. In some cases, the lookup table can be electronically stored in one of the memory devices of the torch control unit and accessed by the processor to identify (eg, automatically identify) consumables. Referring briefly to FIG. 12, in some embodiments, a lookup table 1300 can include plasma gas flow rates (eg, as measured by flow detector 708), plasma gas pressure (eg, as by double Position valve pressure sensor 712 is measured), venting gas flow rate (eg, as measured by venting flow detector 718) and plasma plenum pressure (eg, by plenum pressure sensor) 714 and measured) expected value. Exemplary values are provided for a plurality of different consumables (eg, nozzles), which may be described in terms of a cutting procedure in which one or the like is used (eg, 400 amps (A) mild steel (MS), 260 listed in the illustrative chart. A MS, 200 A MS, 130 A MS, 80 A MS, 50 A MS and 30 A MS). Using the lookup table 1300 and the exemplary pressure and flow detection methods described herein, the type of consumables installed in the torch can be determined (estimated).

In some embodiments, the methods described herein may also include using a flow coefficient equation for describing a relationship between a pressure drop across an orifice and a corresponding flow rate through the orifice to be based on the first pressure, the second One of the orifice sizes (e.g., a characteristic size such as an average width (e.g., average diameter)) is determined by pressure and flow rate. For example, by the pressure of the fluid (eg, the first pressure) that is known to enter the orifice, the pressure of the fluid that discharges the orifice (eg, the second pressure), and the flow rate of the fluid through the orifice, The flow coefficient equation is used to calculate the flow coefficient. For example, in addition to or in addition to using the determined first pressure, second pressure, and flow rate to reference a lookup table to identify a consumable, in some embodiments, a control unit (eg, a processor) A flow coefficient equation can be used, for example, based on calculating and comparing estimated flow restriction component (eg, orifice) sizes for different consumable types to known or expected flow restriction components (eg, orifice sizes) to determine installation The type of consumables in the torch.

Referring to FIG. 10, other methods, such as the exemplary method (1000), may also be implemented to identify one of the heat treatment torches having one of the plasma chambers defined by an electrode and a nozzle. Product. As described below, various methods may include adjusting the flow of gas through the consumable and monitoring the effects of adjustments in flow characteristics observed upstream and/or downstream of the consumable.

For example, one of the inlets of a gas can be directed through a gas supply line to the plasma chamber (1002). For example, gas may be delivered to a gas delivery system (eg, system 700) from a gas supply (eg, gas supply 702) through a gas supply line (eg, a lead) to a plasma torch.

In the case of a gas delivery, at least one of several gas flow characteristics (1004) can be manipulated (eg, adjusted). For example, in some embodiments, a pressure regulator (eg, regulator 710) coupled to a gas supply line can be used to manipulate gas flow to the inlet of the plasma chamber until such as to include a threshold plasma pressure. One of the threshold pressures (1006). That is, if a vent valve (eg, vent valve 716) has been closed (based on the use of the torch), the regulator can be adjusted until a standard is established (eg, a threshold plasma pressure value). The threshold plasma pressure value can be selected based on the capabilities of the gas delivery system. For example, in some cases, the threshold pressure value is about 4.0 pounds per square inch (psig).

Alternatively or additionally, a venting valve (e.g., venting two position valve 716) coupled to one of the vent lines of the plasma chamber can be operatively coupled to control the flow of gas from one of the outlets of the plasma chamber (1008). That is, in some embodiments, a previously opened venting valve can be manipulated (eg, closed) to control gas flow from the outlet of the plasma chamber to limit or prevent gas from passing through the plenum through the venting chamber prior to reaching the standard. Export flows. For example, the vent valve can be closed to restrict gas flow from the outlet of the plasma chamber (eg, substantially eliminating gas flow G2) such that the plasma plenum pressure can be established to a threshold plasma plenum pressure value. Alternatively or additionally, in some embodiments, the venting valve may be opened to vent the venting region downstream of the flow restriction to establish the downstream pressure as atmospheric pressure.

Next, a first value (1010) of one of the operating parameters of one of the torches associated with one of the inlet or outlet flows of the gas can be determined. The operating parameters may include any of a variety of gas flow properties, such as pressure or flow rate to or from one of the consumables. For example, In some embodiments, the at least one operational parameter may include one of the inlet flow supply pressures (eg, as measured by the supply pressure sensor 706), one of the inlet flow rates (eg, by supplying flow detection) Measured by detector 708), one of the inlet valve pressures (eg, as measured by dual position valve pressure sensor 712), or an outlet flow rate (eg, (eg, borrowed) The flow rate or plasma gas flow rate measured by the torch ventilation gas flow detector 718) at the vent line. In some cases, the measurement may be between a gas supply valve and a regulator coupled to the gas supply line (eg, when the regulator is positioned downstream of the gas supply valve) (eg, using the supply pressure sensor 706 amount) Measure the supply pressure of the inlet flow or the flow rate of the inlet flow. In some embodiments, the two-position valve pressure of the inlet flow is measured by a pressure transducer such as a two-position valve pressure sensor 712 positioned downstream of the regulator from the gas supply line.

The consumable (1010) can then be identified based on the first value of the operational parameter. For example, a lookup table that associates one or more consumables with respective values of one or more operational parameters can be used to identify consumables based on the first value of the operational parameters. For example, the lookup table 1300 as discussed above can be used to identify one of the consumables installed in the torch.

In some cases, method 1000 also includes manipulating (eg, opening) a venting valve after the standard is reached to allow gas to flow from the plasma chamber through the outlet of the vent line (eg, to generate gas flow G2) and to determine one of the operating parameters The second value. Next, the first and second values of the observed operational parameters can be used to identify consumables. For example, in some embodiments, the vent valve may be first closed such that substantially only gas flow G1 exits the lance and pressure may be applied within the plasma plenum by adjusting a supply pressure regulator (eg, regulator 710) Establish a threshold pressure value (for example, 4 psig). The first value of the plasma gas flow or the two-position valve pressure is determined upon reaching the standard (ie, reaching the threshold pressure value in the vent line and the plasma plenum) (eg, as measured by the pressure sensor 712) In the event that the venting valve can be manipulated (eg, partially or fully open) such that the downstream venting zone becomes exposed to atmospheric pressure and thereby creates a gas flow G2.

With the vent valve open, one of the operating parameters can be measured for the second value. That is, when the vent valve is opened and both gas flows G1 and G2 are ejected from the torch, various operating parameters are expected (eg, supply pressure of the inlet flow, flow rate of the inlet flow, double valve pressure of the inlet flow, or one) The flow rate of the outlet flow (eg, G1 and/or G2) varies due to additional gas flow. Thus, the second value of the operational parameter and/or the difference or other change between the first value and the second value can be used, for example, to identify a consumable disposed within the torch using a lookup table.

In some cases, the consumable may be one having at least one restriction orifice that is unique to one of a given nozzle design. That is, different nozzle designs (eg, nozzles designed for different material types or current values) may include different sized orifices that can be determined using such methods. For example, one of the nozzles of a particular product line (eg, one of a melt-jet nozzle, a perforated nozzle, or a fine-cut nozzle) may all contain a restriction orifice of the same configuration (eg, the same size).

Additionally, in some aspects, as shown in FIG. 11, another exemplary method (1100) can be implemented for identifying one of the heat treatment torches having one of the plasma chambers defined by an electrode and a nozzle. Consumables (such as a nozzle or a vortex ring).

First, one of the inlets of a gas can be directed through a gas supply valve (e.g., to supply a two position valve 704) and a gas supply line to the plasma chamber (1102) of the torch. For example, in some embodiments, the gas supply line can include a regulator (eg, regulator 710) and a plasma dual position valve (eg, dual position valve 704) coupled thereto to deliver gas to the torch. ).

The inlet flow of the gas can then be adjusted until a threshold pressure associated with the plasma chamber is reached (1104). For example, the regulator can be adjusted to change the pressure within the plasma chamber. In some embodiments, the threshold pressure is one pressure of about 4.0 pounds per square inch (psig) in the plasma chamber. As discussed above, a venting valve coupled to one of the vent lines of the plasma chamber (eg, venting double position valve 716) can be manipulated (eg, adjusted) to limit or prevent self-heating of the gas prior to reaching the threshold pressure value. One of the pulp chamber outlet flows (1106). Example In some cases, the venting valve (eliminating gas flow G2) can be closed such that pressure can be established within the plasma plenum and can reach a threshold.

Once the threshold pressure is reached, a flow characteristic can be determined (1108). For example, in some embodiments, at least one of: (i) one of a pressure of one of the inlet flows (eg, as measured by pressure sensor 706) (1110); (ii) a first value of one of the flow rates of the inlet flow (eg, as measured by flow detector 708) (1112); (iii) one of the first values of the two-position valve pressure of the inlet flow ( For example, as measured by the dual position valve pressure sensor 712) (1114); or (iv) one of the first values of the flow rate of the outlet flow (eg, as measured by the venting flow detector 718) Test) (1116).

After determining the first value of the flow characteristics, the vent valve can be adjusted (eg, manipulated) to allow gas to flow from the outlet of the plasma chamber (1118). For example, in some embodiments, after reaching a threshold and measuring flow characteristics, a venting valve may be opened (eg, partially or fully open) to allow gas to flow from one of the outlets of the plasma chamber (eg, through The flow restricting member exits the venting passage downstream of the flow restricting member. That is, opening the vent valve may cause the torch to begin ejecting the gas stream G2 from the torch. In some cases, an adjustment (eg, manipulation) of the vent valve is performed prior to ignition of the torch to allow gas to flow from the outlet of the plasma chamber.

It is contemplated that the opening of the venting valve changes the flow characteristics of the turret system based on the venting of some of the gases entering the lance into the gas stream G2. Thus, at least one of a plurality of flow characteristics (1120) can be determined (e.g., re-measured) using gas flow from the outlet of the plasma chamber. For example, at least one of: (i) one of the pressures of the inlet flow, a second value (1122); (ii) one of the flow rates of the inlet flow, a second value (1124); (iii) the inlet flow The second value of one of the two-position valve pressures (1126); or (iv) one of the second values of the flow rate of the outlet flow (1128).

The consumables (1130) can then be identified using the first and/or second values of the measured flow characteristics. For example, the measured flow characteristics can be referenced to a lookup table (eg, lookup table 1300, as shown in FIG. 12).

In addition, one or more of the steps or features of the various methods described herein can be implemented in various combinations with each other for identifying a torch consumable.

Although many of the systems and methods herein (eg, method 900, method 1000, and method 1100) have been generally described and illustrated as being primarily used and implemented in connection with a plasma arc torch, other materials such as a water jet system may also be utilized. The system implements it and so on. For example, during use, a fluid such as a gas or liquid (eg, water) can be directed to one or more components of a water jet cutting system (such as a water jet orifice for mixing abrasive particles with fluid) One of the mixing tubes and/or one or more high pressure cylinders or pump elements) to create a high velocity water flow for cutting the material. As with the plasma arc torch discussed above, fluid can be directed through one or more of these components to identify consumables installed in the water jet system in accordance with the methods described herein. For example, fluid pressure and/or flow rate can be monitored upstream and downstream of the water jet orifice to identify the type of orifice installed in the system.

In some aspects, a liquid jet cutting system (eg, a water jet cutting system) can automatically identify system components (eg, consumable components) and transmit them by processing one or more signaling devices assigned to the components. The signal is extracted to extract performance information about the component.

13 shows an exemplary liquid jet cutting system 1300 including a computer numerical controller (CNC) 1302, a positioning device 1304, a cutting head 1306, a high pressure pump 1308, a high pressure line 1310, and an optional abrasive delivery system 1312. . The CNC 1302 is configured to automate and optimize a cutting operation. It acts as an interface between the operator and the cutting system 1300 and may include hardware and/or software to effect cutting parameters and pump setting adjustments. The CNC 1302 also controls the movement of the positioning device 1304 (e.g., an XYZ cutting table, robot, conveyor system, etc.) configured to position a workpiece and/or cutting head 1306 for precise cutting. The abrasive delivery system 1312 can interact with the CNC 1302 to measure an exact amount of abrasive for injection into the liquid jet stream.

The high pressure pump 1308 is configured to generate an ultra-high pressure liquid flow for delivery to the cutting head 1306 via the high pressure line 1310. In order to achieve a high pressure, the high pressure pump 1308 can include an increase A booster (not shown) that includes a double-headed reciprocating pump that is typically driven by an output from a hydraulic pump. In this configuration, hydraulic fluid is cyclically applied to the opposite side of a relatively large diameter "piston", wherein the piston has been attached to the first and second oppositely directed plungers having relatively small diameters and mounted to the opposite Guide the cylinder. In operation, during one of the pressure strokes in a cylinder, water is drawn through a low pressure to other cylinders during its suction stroke. Thus, as the hydraulic piston and plunger assembly reciprocate back and forth, high pressure water is delivered to one side of the self-energizer and low pressure water fills the opposite side. In some embodiments, an attenuator or a liquid trap (not shown) is fluidly coupled to the booster to buffer pressure fluctuations caused by the reversal of the booster.

14 shows an exemplary configuration of a cutting head 1306 of the liquid jet cutting system 1300 of FIG. 13 including a communication network. In general, the cutting head 1400 of Figure 14 serves a number of functions including, but not limited to, establishing a high velocity jet of liquid capable of cutting; providing a conduit for introducing a liquid jet to a workpiece; Introduced to the liquid jet; and centered the liquid jet for precise, accurate positioning relative to the workpiece. As shown, the cutting head 1400 includes an orifice assembly 1402 (or "aperture", and thus the terms are interchangeable herein) for receiving high pressure liquid from the pump 1308 via the inlet 1401 and allowing the liquid to be at a supersonic speed. Small openings are discharged. The size of the orifice opening varies depending on the material properties and thickness of the cut workpiece and is typically between 0.003 and 0.025 inches. The orifice assembly 1402 can include an orifice gemstone (not shown), an orifice support (not shown), and an orifice holder (not shown). The cutting head 1400 also includes an abrasive inlet 1404 for introducing an abrasive for mixing with fluid from the orifice assembly 1402, wherein mixing of the fluid and abrasive can occur in one of the cutting heads 1400 located below the orifice assembly 1402. At the mixing chamber 1406. In operation, a liquid jet from one of the orifice assemblies 1402 is adapted to move rapidly through the mixing chamber 1406 such that a Venturi effect in which the liquid pulls the abrasive into itself can be established. The cutting head 1400 further includes a nozzle 1408 for receiving liquid from the chamber 1406. Nozzle 1408 can be used by providing an elongated space (eg, 3 to 4 inches) The liquid and abrasive are mixed to act as a mixing tube before reaching the workpiece. Thus, the orifice assembly 1402 and the nozzle 1408 define at least a portion of the conduit for receiving a liquid jet and introducing the liquid jet to a workpiece. The orifice assembly 1402, the nozzle 1404, and the mixing chamber 1406 can be consumable components because they are subject to erosion by the liquid passing therethrough and therefore require periodic replacement.

FIG. 14 also shows one communication network associated with cutting head 1400. The communication network includes one or more signaling devices 1410 (e.g., 1410a and 1410b) that are each assigned to a consumable component (e.g., aperture assembly 1402 and nozzle 1408) of cutting head 1400. For example, signaling device 1410a can be assigned to aperture assembly 1402 and signaling device 1410b can be assigned to nozzle 1408. Each signaling device 1410 can transmit a signal associated with the consumable component to a receiver 1414. Each signaling device 1410 can be configured to transmit an electrical writing device in the form of one or more signals regarding the respective consumables. Each signaling device 1410 can be substantially identical to the signaling device 202 of FIG. For example, each signaling device 1410 can be a radio frequency identification (RFID) tag or card, a bar code tag or tag, an integrated circuit (IC) board, or the like. In some embodiments, a signaling device 1410 is used to detect one of the consumables' physical characteristics and to transmit one of the detected information (eg, a sensor) in the form of one or more signals. The communication network also includes at least one receiver 1414 for i) receiving signals transmitted by at least one of the signaling devices 1410; ii) extracting information communicated by the signals; iii) providing the extracted data to a processor 1416 is for analysis and further action and iv) as indicated by processor 1416 to write data to one or more of the signaling devices. The processor 1416 can be a digital signal processor (DSP), a microprocessor, a microcontroller, a computer, a computer numerical controller (CNC) machine tool, a programmable logic controller (PLC), a specific application integrated circuit ( ASIC) or similar. The processor can be integrated with the CNC 1302 or can be a standalone computing device.

In some embodiments, each signaling device 1410 is encoded using information regarding the consumables to which the signaling device 1410 is assigned. Encoded information can be general or mixed information, Such as the name, trademark, manufacturer, serial number and/or type of consumables. The encoded information, for example, can include a model to generally indicate the type of consumable such that the consumable is an orifice assembly or a nozzle. In some embodiments, the encoded information such as the consumable material composition, the weight of the consumable and/or the opening size, the date, time and/or location at which the consumable was made, the person responsible for the consumable, and the like Consumables are unique. As an example, the encoded information can provide a unique serial number for each of the manufactured consumable components to distinguish between, for example, nozzle type A, serial number #1, and nozzle type A, serial number #2. As another example, signaling device 1410a can store information regarding the size of the opening of aperture assembly 1402 and signaling device 1410b can store information regarding the size of the opening of nozzle 1408. In general, the information encoded in each of the signaling devices 1414 can be substantially similar to the information encoded in the signaling device 202 of FIG.

In some embodiments, the information is encoded to a signaling device 1410 at the time of manufacture of the corresponding consumable. Information may also be encoded into a signaling device 1410 during the life of the consumable, such as after each consumable is used. The encoded information may include the date, time, duration and location of the consumable use, any anomalies detected during use, and/or consumable conditions after use, such that a record may be established to predict one of the associated consumables Failure event or end of life period. The recorded information may also include the number of pressure cycles through which the consumables are exposed or exposed. As an example, signaling device 1410a may track the number of hours of operation of aperture assembly 1402 and thus allow processor 1416 to determine or predict the time at which aperture assembly 1402 exceeds the warranty period or near the end of its life. Similarly, signaling device 1410b can track the use of nozzle 1408 to predict the end of warranty expiration and/or end of life.

The information encoded to a signaling device 1410 can also specify operational parameters and/or instructions that allow the processor 1416 to automatically configure at least one operational parameter of the liquid jet cutting system 1300. As an example, due to the use of the abrasive in the liquid jet, the opening of the nozzle 1408 can increase over time, thus affecting the quality of the cutting operation. Thus, the signaling device 1410b associated with the nozzle 1408 can store the size of the opening of the nozzle 1408, thus allowing the processor 1416 to predict It increases and automatically adjusts certain operational parameters such as the cut settings to compensate for the predicted increase. As another example, the size of the opening of the orifice assembly 1402 is associated with the stroke rate of the pump 1308 that establishes a flow of high pressure liquid. Thus, processor 1416 can use the aperture size information stored in signaling device 1410a to predict the pump stroke rate. For example, processor 1416 can use the predicted stroke rate to diagnose the health of pump 1308 by comparing the predicted stroke rate to the measured actual stroke rate. If the actual stroke rate is faster than the predicted stroke rate, it may indicate, but is not limited to, a high pressure leak, a blown orifice, a bleed valve failure, a lift leak or failure, a sump leak, and/or an internal stop. Any number of adverse conditions for valve failure. For example, a high pressure leak, a blown orifice, a bleed valve failure, or a leak in a liquid trap can cause the booster to stroke too fast in both directions. A lift leak or failure can cause the booster to stroke too quickly in one direction. In general, the pull-up may fail due to the debris being prevented from closing, resulting in transitional lubrication and/or wear of the contaminated parts. In other examples, information stored on each or both of the signaling devices 1410 can be used by the processor 1416 to perform the following adjustments: (i) adjustment to the liquid jet by interaction with the abrasive delivery system 1312 The composition/amount of additive; (ii) adjusting the positioning of the workpiece relative to the cutting head 1306 by adjusting the positioning device 1304; and/or (iii) changing the stroke rate of the pump 1308. In some embodiments, the combination of information stored in signaling device 1410 allows processor 1416 to automatically set one or more of the cutting parameters to optimize efficiency and maximize the life of nozzle 1408 and/or orifice assembly 1402.

In some embodiments, the encoded material of signal device 1410 provides information about other related system components. For example, the encoded data can identify other system components that are compatible with the assigned consumables, thereby assisting in the installation of the entire consumable set in a liquid jet cutting system to achieve certain performance metrics. For example, the processor 1416 can use the aperture related information stored in the signaling device 1410a or the nozzle related information stored in the signaling device 1410b to select to establish a suitable type of pump 1308 having a sufficiently high pressure one cutting jet or to select one A suitable type of abrasive is introduced to the jet stream. The processor 1416 can also use the aperture related information stored in the signaling device 1410a to select the appropriate type of nozzle 1408 or vice versa. Of course.

In some embodiments, a signaling device 1410 can write once, for example, to encode information about the consumable when the consumable is initially manufactured. In some embodiments, a signaling device 1410 can be written multiple times, such as multiple times throughout the life of the corresponding consumable.

In some embodiments, each of the signaling devices 1410 is located inside the cutting head 1400 (eg, on an inner surface of the cutting head body) and/or on one of the consumable components of the cutting head 1400. For example, a signaling device 1410 can be attached to the surface of one of the consumables that is ultimately mounted within the interior of the cutting head 1400. A signaling device 1410 can also be attached to one of the components within the cutting head 1400 other than the assigned consumable. In some embodiments, a signaling device 1410 is coupled to an external source that is not associated with the cutting head 1400 entity. For example, the signaling device 1410 can be attached to one of the consumables for storing consumables and once installed in the cutting head. In an exemplary configuration, a signaling device 1410a for storing information about the orifice assembly 1402 is located on one surface of the orifice assembly 1402 (eg, mounted on the surface of the orifice support) for A signaling device 1410b that stores information about the nozzle 1408 is located on the surface of the nozzle 1408. Additionally, both signaling devices 1410 can be placed in the low pressure region of the cutting head 1400 to minimize exposure to high pressure liquid during the cutting operation.

In some embodiments, a signaling device 1410 is designed to be durable, ie, functioning during and after one or more cutting operations. For example, signaling device 1410a can be sufficiently robust to withstand ultrasonic cleaning of orifice assembly 1402 to remove deposits. In some embodiments, a particular cleaner is used to avoid injury signaling device 1410a. In some embodiments, a signaling device 1410 can be discarded after each cutting operation or after several operations.

Each of the signaling devices 1410 can wirelessly transmit its stored information to the receiver 1414 in the form of one or more signals. In general, receiver 1414 can be substantially similar to receiver 204 of FIG. Receiver 1414 is adapted to process signals from respective signaling devices 1410 to extract relevant information about consumables corresponding to signaling device 1410 and to forward the data to Processor 1416 is for analysis. In some embodiments, the receiver 1414 is located in the cutting head 1400 or on the cutting head 1400. For example, the receiver 1414 can be located in the cutting head 1400 proximate to the signaling device 1410, such as on the body of the abrasive inlet 1404 and/or on one of the internal surfaces of the cutting head body. In some embodiments, the receiver 1404 is at a location external to the cutting head 1400, such as attached to the processor 1416. In some embodiments, the signaling device 1410 is an RFID tag, in which case the receiver 1414 is used to interrogate one of the RFID tags or one of the readers. Each of the reader and tag can include an antenna for receiving and transmitting signals. Another component of an RFID communication system implements an intermediary software application for connecting data from a reader to a panel (eg, a printed circuit board) of an external host software system. The panel can perform one or more of the following functions: retrieving data from one or more readers; filtering data feeds to external application software; monitoring tag and reader network performance; extracting history and self An analog signal received by a reader is converted into a digital signal for external transmission. Yet another component of an RFID communication system is configured to transmit a digital signal from a panel to a connector of an external host software system. In some embodiments, a reader is used to interact with a plurality of RFID tags. Alternatively, multiple readers that interact with each of the RFID tags can be used. In some embodiments, a signal interface is used to connect information from one or more readers to an external processor. Alternatively, multiple media panels can be used to connect the respective readers to an external processor.

15 shows an illustrative design for housing a cutting head of one of the RFID communication systems, such as cutting head 1400 of FIG. 15 shows a cylindrical housing 1502 that is sealed for receiving a panel 1506 using one or more o-rings 1504. The outer casing 1502 can be substantially circular in cross section. One or more slots (not shown) may be drilled into the interior of the housing 1502 to hold the media panel 1506 in position. At least one nut 1522 can be used to connect the outer casing 1502 to the abrasive inlet of the cutting head body such that the outer casing 1502 is rotatable relative to the cutting head body. Additionally, a connector 1520, such as a Fisher© or Truck© connector, can be used, for example, at the interface panel 1506. Data in the form of an analog signal is transmitted between an external processor, such as processor 1416 of FIG. 4 or CNC 1302 of FIG.

Additionally, one or more wires 1508 are used to connect at least one reader 1510 to the media panel 1506. Each of the media panels 1506 can have a plurality of readers coupled thereto. Wire 1508 is long enough to be routed through housing 1502 to reach panel 1506. At least one RFID tag 1512a is mounted in the cutting head to store information about the aperture assembly 1514 and at least one additional RFID tag 1512b is used to store information about the nozzle 1516. The reader 1510 is adapted to communicate with one or both of the RFID tags via the antenna 1518. As shown in Figure 15, each RFID tag 1512 has a dedicated antenna located nearby. Alternatively, a single antenna can be used for both RFID tags 1512. The reader 1510 can forward the stored information on the respective tags to the mediation panel 1506 via wires 1508.

16a-16c illustrate another illustrative design for housing a cutting head of one of the RFID communication systems, such as cutting head 1400 of FIG. As shown, one of the housings 1602 is sealed with one or more spacers 1604 to accommodate a media panel 1606. The outer casing 1602 can be substantially rectangular in outline, as more clearly shown in Figure 16b. At least one hollow bolt (not shown) can be used to connect the outer casing 1602 to the cutting head body such that the outer casing 1602 is rotatable relative to the cutting head body. Additionally, one or more connectors 1620, such as a dual coaxial connector, can be used to transfer data in the form of a digital signal between the interface panel 1606 and an external processor. In some embodiments, if the interface panel 1606 transmits an analog signal, the top panel 1602a of the housing 1602 is non-conductive because the connector 1620 is coupled to the interface panel 1606. Additionally, the top sheet 1602a is sealed at a region where the outer casing 1602 can contact the connector 1620. One or more wires 1608 are used to connect at least one reader 1610 to the mediation panel 1606 through one of the bodies of the abrasive inlet. The placement of RFID tags, readers, and antennas in this design can be significantly the same as the design of Figure 15.

17 shows yet another illustrative design for housing a cutting head of one of the RFID communication systems, such as cutting head 1400 of FIG. Figure 17 can be substantially similar to Figures 16a through 16c The design, except for the housing 1702, includes both the interface panel 1706 and the reader 1704. Therefore, a very long wire is not required to connect the reader 1704 to the media panel 1706. Another advantage is that the signals transmitted by connector 1708 to an external processor are less susceptible to noise and are therefore more robust. This is because the interface panel 1706 is adapted to convert an analog signal received from a reader into a digital signal within the cutting head, wherein the resulting digital signal transmitted is mostly immune to noise. In addition, because the insulation is mostly used to prevent electrical noise to conduction in the analog signal, the top sheet 1702a of the outer casing 1702 no longer needs to be insulated for the same reason. In some embodiments, the cutting head design panel 1506 of FIG. 15 and/or the cutting head design panel 1606 of FIGS. 16a-16c are configured to transmit analog signals (ie, not converted to the interior of the respective cutting head) Digital signal). Even though the transmission of this mode tends to be more susceptible to external noise and therefore requires insulation, the vias are typically smaller. However, in other embodiments, the interfaces 1506 and 1606 can be easily modified to convert the analog reader signal to a digital signal prior to transmission to an external processor.

15 through 17 illustrate at least one reader for communicating information from an RFID tag to one or more connectors via at least one interface panel in an RFID communication system. In some embodiments, multiple readers that each communicate with at least one RFID tag can be used. In addition, a wire is used to connect the various readers to the connector. 18 shows an illustrative configuration of one of the cutting heads of a cutting head 1400, such as the cutting head 1400 of FIG. 14, configured to accommodate a wired connection between a plurality of readers and a connector. As shown, two readers are provided, the reader 1802a being configured to communicate with an RFID tag 1804a associated with the aperture assembly 1806, and the reader 1802b is configured to be associated with the nozzle 1808 The RFID tag 1804b communicates. The reader 1802 can be located proximate to the cutting head of the respective label 1804 while minimizing the distance between it and the connector (not shown) via the interface panel 1810 (ie, the length of the wire used). As shown in FIG. 18, the reader 1802a is positioned between the aperture assembly 1806 and an interior surface of the cutting head body 1800 on one side of the closest plate 1810. Similarly, reader 1802b is located at nozzle 1808 and cutting head body 1800 on one side of the closest plate 1810. Between an internal surface. Additionally, a conduit 1812 is machined into the cutting head body 1800 to allow the wires 1814 to be delivered therethrough to the mediation panel 1810 and terminate at the connector. Wire 1814 includes wires 1814a and 1814b for connecting readers 1802a and 1802b to board 1810, respectively. In some embodiments, the conduit 1812 is not milled. Conversely, electrical discharge machining (EDM) is used to establish this feature in the cutting head body 1800. In some embodiments, a gasket 1816, such as a flexible neoprene gasket, is press fit into the conduit 1812 to prevent water from leaking into the area where the label and/or reader resides. . The gasket 1816 can include an opening to allow the wire 1814 to pass therethrough while providing a waterproof seal.

Figure 19 shows an exemplary procedure for operating the liquid jet system of Figure 13. The process begins when at least one replaceable component is mounted into a cutting head of a liquid jet cutting system, such as in cutting head 1306 of system 1300 (in step 1902). The replaceable component can be a consumable such as one of the cutting head nozzles (nozzle 1408) or an orifice assembly (e.g., orifice assembly 1402). At least one identification mechanism, such as one of the signaling devices (eg, signaling device 1410) in the form of an RFID tag, is assigned to the replaceable component. The identification mechanism can be attached to one of the surfaces of the replacement element. The identification mechanism is adapted to communicate information about its assigned replaceable elements to a reader (eg, receiver 1414) of the liquid jet cutting system (in step 1904). Exemplary information includes the type of replaceable component, the time or duration of use of the component, and/or the conditions under which the component is used. The reader can forward information to a processor (e.g., processor 1416 and/or CNC 1302) via a panel (e.g., board 1506) and a connector (e.g., connector 1520). In response, the processor can automatically adjust at least one operational parameter of the cutting system based on the received information (in step 1906). For example, the processor can use the received information to determine a period of use of the replaceable component, one of the components predicts the expected life, one of the pumps of the liquid jet cutting system predicts the stroke rate, and/or is used to cut a workpiece A cut setting. An exemplary adjustment by one of the processors may include outputting an alarm signal or message to alert an operator to an end of life event, a potential leak based on the predicted stroke rate (after comparing the predicted stroke rate to an actual stroke rate) and/ Or a move fails. The processor can also automatically adjust the system to implement a new cut setting.

Based on the teachings of this specification, one of ordinary skill in the art can readily determine how to combine such various embodiments. In addition, modifications will occur to those skilled in the art upon reading this specification.
