Description

  The present invention prevents the breakage, breakage, and strong wear by measuring and managing in real time the so-called sharpening point temperature of the grinding tool such as end mills, drills, taps, etc., which is the workpiece of the sharpening machine. In addition, the present invention relates to a measuring / managing apparatus for a sharpening cutting apparatus that guarantees that the sharpening cutting is performed under appropriate processing conditions for each sharpening cutting apparatus.

  In general machining equipment, especially grinding (grinding, grinding and cutting), the optimum tool specifications (material, shape, number of blades) determined according to the material, thickness and shape of the workpiece , Cutting angle, etc.), rotation speed (rotation speed), cutting speed and other machining conditions are handed down as empirical values. However, in practice, the temperature at the processed portion of the workpiece is usually higher at the end at the start and at the end, although the same processing conditions are maintained. This is because as the machining progresses, the temperature of the part of the workpiece to be machined is not only the frictional heat with the grinding tool (tool), but also the frictional heat of the part where the machining has finished is propagated and accumulated. It is thought that it is done.

  At the same time, since the cooling effect due to the radiation and radiation of heat to the surrounding environment and the propagation to other than the processing site is also taken into account, especially when high-speed processing is performed, there is a variation in the processing quality of the processing part of the workpiece. There was a problem that it was likely to occur. Therefore, in the apparatus disclosed in Patent Document 1, a temperature sensor is placed inside the vicinity of the tip of the tool cut into the workpiece, and the temperature near the tip of the tool close to the temperature of the machining portion of the workpiece. The rotation speed of the tool, the insertion speed into the machining member, or the like is controlled so that the temperature falls within a predetermined management range (processing conditions), or the cooling effect by the cutting fluid is controlled. This makes it possible to reduce variations in the finished quality in the processed part of the workpiece, and to measure the tool breakage, damage, and strong wear in real time, before breakage, damage, and strong wear occur. It became possible to change tools relatively easily.

Japanese Patent Laying-Open No. 2015-036174

  By the way, in the apparatus (temperature measurement tool) disclosed in Patent Document 1, appropriate processing condition data (such as a working temperature range, a cutting speed of the processing tool, and a rotation speed) according to the material and thickness of the workpiece are stored in advance. Then, the machining tool is controlled using the machining condition data. However, such appropriate machining condition data generally differs for each type of machining apparatus and for each machining tool, and strictly speaking, differs for each individual machining apparatus and tool. Therefore, it is necessary to perform individual management for each individual sharpening processing apparatus and processing tool and reflect the result in the processing condition data. In addition to the wide variety of processing tools used in sharpening processing equipment, since general-purpose processing tools can be applied originally, imitations other than dedicated tools for measurement may be used. If tool management is not performed, control using appropriate machining condition data cannot be performed.

  The present invention has been created in view of the circumstances as described above, and is a polishing cutting apparatus and a processing tool measuring / managing apparatus capable of guaranteeing a finish under appropriate processing conditions determined in advance. The purpose is to provide a mechanism to stop the sharpening machine before the time of tool replacement or tool failure.

It is preferably formed as information for controlling the apparatus.

  According to the measuring / managing apparatus for the abrasive cutting apparatus of the present invention, at least an abrasive cutting tool into which a sensor such as a thermocouple can be inserted and an exchangeable tool holder for holding the same are used. While measuring the physical state value of the cutting tool in real time, the operation control of the sharp cutting apparatus can be executed under appropriate processing conditions determined in advance. Specifically, the measurement / management device for this cutting machine has a physical state value during actual machining obtained from each sensor in the machining tool, and a security code for executing control processing of the grinding machine.

It is preferred that information is included.

  The measurement and management device for this grinding machine is an integrated unit with a sensor in the through hole or half-through hole in the grinding tool and a sensor data transmitter in the tool holder attached to the grinding machine. Since it is configured, it can be used as an alternative to the tool holder of a general-purpose grinding machine. Therefore, if a system for authenticating the security code is set on the control device side, this measurement / management device can be easily used for a general-purpose grinding machine. As a result, if the control devices are unified, it becomes easy to manage a plurality of sharpening devices simultaneously.

For example, an individual identification ID is given to the sharpening tool, and this is read by a separate reader, or if the sharpening tool and the tool holder are integrated, the individual identification ID is given to the connector of the cable from the sensor. By connecting a cable from the sensor data transmitter in the tool holder to the connector, information may be read by a reader (including the sensor data transmitter) in the tool holder.

  FIG. 1 shows a perspective view of an example of a sharp cutting apparatus 100 used in the measurement / management apparatus of the present invention. As a premise for explaining the embodiment of the present invention, the configuration of the grinding machine 100 and the grinding process will be outlined below. The sharpening processing apparatus 100 is generally configured to include a tool holder gripping portion 3, a work stage 42, a head abutment 43, a head 44, and an operation panel 45. For members having reference numerals not shown in FIG. 1, refer to FIG.

  First, the tool holder 2 in a state in which a processing tool 1 that makes rotational contact (contact direction = arrow Z direction, rotational direction = direction of the axis of the arrow Z) with a member to be processed (not shown) is sharpened. The tool 100 is attached to the tool holder grip 3 of the apparatus 100. As a result, the tool holder gripping part 3, the tool holder 2, and the processing tool 1 (hereinafter also referred to as “grinding tool 1”) rotate together. Further, the workpiece is placed on the upper surface of the work stage 42, and is fixed using a fixing clamp (not shown), a fixing bolt (not shown), or the like. In this state, the user operates the operation panel 45 (including the control device 5 described later), moves the work stage 42 in the X direction, and stops / positions when the processing tool 1 is positioned immediately above the processing position of the workpiece. To do. Next, the operation panel 45 is operated in a state of being stopped and positioned on the workpiece, the machining tool 1 is lowered and brought into contact with the workpiece, rotated while being pressed, and moved in the machining direction. At this time, the user inputs in advance parameters such as a tool load applied to the workpiece, a tool moving speed, a tool rotation speed, and the like, and sets machining conditions used for the sharpening machining.

  When the setting on the operation panel 45 is completed, the processing tool 1 is rotated immediately above the workpiece to reach the set tool rotation speed, and then the head 44 is moved downward in the Z direction so that the machining start point of the workpiece is reached. The processing tool 1 is pressed. When the head 44 presses the machining tool with a preset tool load against the workpiece, the contact portion between the machining tool 1 and the workpiece is ground and frictional heat is generated. Thereafter, the workpiece is sharpened by moving the head support 43 in the Y direction at the set tool moving speed and carrying the processing tool 1 from the processing start point to the processing end point. After the desired processing is achieved, the head 44 is moved upward in the Z direction while maintaining the rotation of the processing tool 1, and after the processing tool 1 is pulled up from the processing end point, the rotation of the processing tool 1 is stopped. By repeating this process a plurality of times, the sharp cutting process is completed.

  Next, the tool holder 2 and the processing tool 1 that are gripped and fixed to the tool holder gripping portion 3 of the above-described grinding cutting apparatus 100 will be described. FIG. 2 is a diagram showing an example of a schematic block configuration of the abrasive cutting apparatus 100. FIG. 2 also shows a schematic vertical cross-sectional structure of the processing tool 1, the tool holder 2, and the tool holder gripping portion 3, and shows devices and members associated therewith. The tool holder gripping portion 3 is usually a cylindrical container, and the columnar tool holder 2 can rotate around the central axis (main shaft 20) of the column via a bearing 31. Is held in. At this time, the tool holder 2 is rotationally driven by a spindle motor 6 attached to the tool holder gripping portion 3 side. Further, a processing tool 1 is attached to a lower tip portion of the tool holder 2, and the processing tool 1 is rotationally driven by the spindle motor 6 together with the tool holder 2.

  In the present embodiment, a through hole that reaches from the upper end to the lower end or a semi-through hole that does not penetrate from the lower end to the lower end is provided inside the processing tool 1, and among the sensors 13 such as a temperature sensor, a strain sensor, and an acceleration sensor. One or more are embedded. Further, the strain sensor and the acceleration sensor may be placed inside the tool holder. Although three sensors 13 are depicted in FIGS. 2 and 3, the number of sensors 13 is not limited to three. The number of sensors 13 may be one, two, or four or more. The plurality of sensors 13 may all be the same type of sensor such as a temperature sensor, or each may be a different type of sensor. The combination of the types of the plurality of sensors 13 is arbitrary.

  The detection value of the sensor 13 is transmitted to a data display unit (not shown) and / or the control device 5 via a sensor data transmitter 8 attached to the tool holder 2 and a receiver 9 attached to the tool holder grip 3. Sent to. Since the sensor data transmitter 8 rotates together with the tool holder 2, the receiver 9 includes, for example, an antenna around the sensor data transmitter 8, and is wirelessly connected to the sensor data transmitter 8. Communicate with. The control device 5 controls the spindle motor 6 based on, for example, the temperature (tool temperature) detected by the sensor 13. In this case, for example, when the tool temperature is lowered, the rotation of the spindle motor 6 may be decelerated or the flow amount of the cutting fluid (not shown) may be increased. Further, when the tool temperature is raised, the rotation of the spindle motor 6 may be accelerated or the flow amount of the cutting fluid (not shown) may be reduced. FIG. 3 is a diagram showing an example of the configuration of the sensor data transmitter 8.

  As shown in FIG. 3, the sensor data transmitter 8 includes a sensor signal input port 81, an A / D (Analog to Digita1) conversion unit 82, a data processing unit 83, a radio signal output unit 84, and the like. The data processing unit 83 includes a sensor detection value acquisition unit 831, a sensor detection value storage unit 832, a security code storage unit 833, a communication frame generation unit 834, and the like. The sensor signal input port 81 includes a plurality of analog signal input terminals (not shown), and a signal line from the sensor 13 is connected to each of the analog signal input terminals. In FIG. 3, signal lines from three sensors 13 are connected to the sensor signal input port 81, but the number of sensors 13 connected to the sensor signal input port 81 is not limited to three. For example, in the case of a general-purpose type drill as the processing tool 1, the number of sensors 13 provided in the half through hole is often one because the diameter is small.

  The A / D conversion unit 82 converts an analog electric signal from the sensor 13 input via the sensor signal input port 81 into a digital detection value (numerical data), and converts the digital detection value into the data processing unit 83. Output to. The sensor detection value acquisition unit 831 of the data processing unit 83 associates the digital detection value output from the A / D conversion unit 82 with the sensor ID that is identification information of the sensor 13, and detects the sensor detection value storage unit 832. To store. In the security code storage unit 833, a security code set in advance according to the configuration of the sensor 13 connected to the sensor data transmitter 8 (the type and number of the sensors 13), the type of the main body of the processing apparatus 100, and the like. It is remembered. Hereinafter, in this specification, the security code stored in the security code storage unit 833 is referred to as security code # 1. The security code # 1 may be displayed (generated) using an IC tag, an IC chip, a barcode and its reader, a connection cable with a built-in authentication mechanism, or an electronic board such as a transmitter or a receiver. Even if they are not used in the form accompanying them, the individual recognition that is the initial purpose is possible as long as they can be mutually confirmed, and the security (individual recognition) that is the object of the present application can be achieved. The security code # 1 may be replaced with an individual identification code such as a performance constant, manufacturer, model name, and serial number of the sensor and a combination thereof. In the following description, it is assumed that the security code storage unit 833 is configured by a nonvolatile memory such as a flash memory. The security code # 1 is written in the security code storage unit 833 including the nonvolatile memory in accordance with the type and the type and configuration of the sensor 13 when the processing apparatus 100 is manufactured.

  If the security code # 1 can identify the type and number of sensors 13 connected to the sensor data transmitter 8 among the plurality of processing devices 100, the type of the main body of the processing device 100, and the like. Any code can be used. For example, the identification information which can identify the processing apparatus 100 individually, such as the manufacturing number of the processing apparatus 100, may be sufficient.

  In addition to the sensor 13, the polishing tool 1 may be provided with a security code storage unit 835 for storing individual identification information (ID). In this case, the security code storage unit 835 stores a security code # 1-1 set in advance according to information related to the specifications of the grinding tool 1. The security code # 1-1 includes, for example, the manufacturer, model number, serial number, etc., of the appropriate sharpening device 100, the heat-resistant temperature, size information, recommended rotational speed, and installation hole information of the sensor 13 of the sharpening tool 1. (The number of through-holes or semi-through-holes described above, hole position, hole diameter, etc.), the type and use of the sensor 13, and the like are included.

  As a technique for causing the security code # 1-1 stored in the security code storage unit 835 to appear (generate), an IC tag, an IC chip, and a barcode are attached to the polishing tool 1, and this is used as a dedicated reader. A case of reading with (reader) 14 or a contact terminal is conceivable. FIG. 3 shows an example in which an IC tag is attached to the sharpening cutting tool 1 and read by the reader 14 as an example. In addition, although not shown, when the sensor 13 is integrated into the sharpening cutting tool 1, an IC chip is embedded in the connector on the sensor side of the cable from the sensor 13 to the sensor data transmitter 8 or a barcode is given. For example, it is conceivable to use a connection cable with a built-in authentication mechanism for the cable on the sensor data transmitter side.

  Further, the communication frame generation unit 834 generates a communication frame 85 (see FIG. 4) when transmitting the detection value of the sensor 13, the security code # 1 (# 1-1), and the like to the control device 5. The radio signal output unit 84 modulates data of the communication frame 85 generated by the communication frame generation unit into a radio signal by a predetermined method, and transmits the modulated radio signal to the receiver 9. The sensor data transmitter 8 converts the detection value from the sensor 13 into a digital value by the A / D converter 82, generates a communication frame 85 as shown in FIG. For example, it is assumed that it is repeatedly executed at a predetermined time interval such as an interval of 1 second.

  FIG. 4 is a diagram showing an example of the configuration of the communication frame 85 transmitted from the sensor data transmitter 8 to the control device 5 via the receiver 9. As shown in FIG. 4, the communication frame 85 includes fields including a header code 851, a security code 852, and a plurality of sensor ID and sensor detection value sets 853. Here, the header code 851 is a code determined by the communication method between the sensor data transmitter 8 including the modulation method and the control device 5, and often includes the frame length of the communication frame 85. . In the security code 852 field, security codes # 1 and # 1-1 stored in the security code storage units 833 and 835 are set. The field of the security code 852 may be included in the header code 851 or may be a field independent of the header code 851.

  In the field consisting of the sensor ID and sensor detection value set 853, the sensor 13 connected to the sensor data transmitter 8, the sensor ID for identifying the sensor, and the detection value detected by the sensor 13, respectively. Is set. The sensor ID here includes information for identifying the type of the sensor 13 (temperature sensor, strain sensor, etc.) in addition to the information for individually identifying the sensor 13. FIG. 5 is a diagram illustrating an example of the configuration of the control device 5 according to the first embodiment. As shown in FIG. 5, the control device 5 includes a communication frame decomposition unit 51, a security code authentication unit 52, a processing device control processing unit 53, a control signal output unit 54, a sensor detection value storage unit 55, and a processing device control with security code. The data storage unit 56 is included. The communication frame disassembling unit 51 disassembles the communication frame 85 received via the receiver 9 to obtain a security code 852 (security code # 1, # 1-1), sensor ID and sensor detection value set 853. . The security code 852 is transferred to the security code authenticating unit 52, and data of the sensor ID / sensor detection value set 853 is temporarily stored in the sensor detection value storage unit 55. In the grinding control data storage unit 56 with a security code, grinding cutting control data 561 for controlling the spindle motor 6 and the tool movement drive device 7 in accordance with the material of the workpiece 101 and the sensor detection value of the sensor 13 (FIG. 6) is stored in advance. In the grinding code control data storage unit 56 with a security code, a security code 562 (hereinafter referred to as security code # 2) associated with the grinding control data 561 is stored. The security code # 2 is set when the sharpening apparatus 100 is manufactured, and the value is the security code # 1, # 1 stored in the security code storage unit 833 of the sensor data transmitter 8. Same as -1.

  The security code authenticating unit 52 compares the security codes # 1 and # 1-1 acquired by the communication frame decomposing unit 51 with the security code # 2 stored in the sharpening control data storage unit 56 with security code. Then, if the two match, the processing of the sharpening control processing unit 53 is started. If they do not match, the processing of the sharpening control processing unit 53 is not started. Note that an example of processing in the security code authenticating unit 52 will be described separately with reference to FIG. The ground cutting control processing unit 53 refers to the ground cutting control data 561 stored in the ground cutting control data storage unit 56 with a security code, and based on the sensor detection value stored in the sensor detection value storage unit 55, etc. A control value for the spindle motor 6 and the like is obtained. Then, the control value is output to the spindle motor 6 via the control signal output unit 54. The basic concept of the grinding cutting control in the present embodiment will be described with reference to FIG. 7 separately, and an example of processing of the grinding cutting control processing unit 53 will be described with reference to FIG. 9 separately. To do. The control device 5 configured as described above includes one or a plurality of arithmetic processing devices, storage devices (semiconductor memories, hard disk devices, etc.), and input / output devices (keyboards, buttons, display devices, etc.). Realized by computer.

  FIG. 6 is a diagram showing an example of the configuration of the sharpening control data 561 stored in the sharpening control data storage unit 56 with a security code. As shown in FIG. 6, the grinding cutting control data 561 is associated with a management temperature range, a management judgment temperature range, a spindle motor rotation speed, a tool movement speed, and the like for each material of the workpieces 101a and 101b and their plate thicknesses. Configured. The sharpening control data 561 is associated with a predetermined security code 562 (security code # 2). Here, in FIG. 6, the management temperature range is a temperature for managing the tool temperature detected by the sensor 13 (temperature sensor), and includes an upper limit value and a lower limit value. When the processing by the processing tool 1 is being performed, the tool temperature, that is, the temperature of the processing parts of the processed members 101a and 101b that are polished and cut by the processing tool 1, is the upper limit of this management temperature range. And is managed so as to be within the range of the lower limit.

  Further, the upper limit value and the lower limit value of the management determination temperature range in FIG. 6 are temperatures included in the management temperature range. That is, the upper limit value of the management determination temperature range is lower than the upper limit value of the management temperature range, and the lower limit value of the management determination temperature range is set higher than the lower limit value of the management temperature range. In general, in temperature control of an object having a large heat capacity, even if the temperature of an object that is in the process of temperature rise is detected and the amount of heating is reduced, the temperature overshoots without immediately turning down. Similarly, even if the temperature of an object that is falling is detected and the heating amount is increased, the temperature undershoots without immediately turning up. Therefore, in the present embodiment, by allowing the upper limit value and the lower limit value of the management determination temperature range to be set appropriately, temperature overshoot and undershoot can be allowed in temperature control.

  In FIG. 6, the initial value of the spindle motor rotational speed means the initial value of the rotational speed of the spindle motor 6 when the machining tool 1 is pressed against the workpieces 101a and 101b. The steady value # 1 and steady value # 2 of the spindle motor rotation speed and the steady value # 1 and steady value # 2 of the tool movement speed are the values of the rotation speed of the spindle motor 6 and the movement speed of the machining tool 1 during machining. Control value. Here, the steady value # 1 and the steady value # 2 are control values set when the tool temperature exceeds the lower limit value and the upper limit value of the management determination temperature range, respectively.

  As described above, the upper limit value and lower limit value of the management temperature range constituting the sharpening control data 561, the upper limit value and lower limit value of the management determination temperature range, the initial value of the spindle motor rotation speed, the steady value # 1, the steady value # 2, and the tool It is assumed that values such as steady value # 1 and steady value # 2 of the moving speed are obtained in advance through experiments or simulations according to the material and plate thickness of the workpieces 101a and 101b. . The ground cutting control data 561 having the above configuration can be regarded as machining condition data when the workpieces 101a and 101b are machined by the grinding machine 100.

  Next, as the security code 562, as described above, the security code # 1 stored in the security code storage unit 833 and the security code # 1-1 stored in the security code storage unit 835 are the same code. Code # 2 is stored. This is because the configuration of the grinding control data 561 stored in the control device 5 is at least the configuration (type, number, etc.) and processing of the sensor 13 provided in the machining tool 1 of the grinding device 100. It represents that the tool 1 is consistent with the configuration (model number, heat resistant temperature information, etc.) of the individual identification information (individual identification ID) assigned to each tool 1. That is, it means that the grinding cutting control data 561 can be used for controlling the spindle motor 6 and the tool movement driving device 7 of the grinding cutting apparatus 1.

  As described above, the security code # 1 and the security code # 2 are set at the same time when the sharpening apparatus 100 is manufactured, and the security code # 1-1 and the security code # 2 are set when the machining tool 1 is introduced. Thus, the same code is set according to the lineup of the machining tool 1. Therefore, normally, the authentication by the security code authenticating unit 52 is always successful. However, the combination of the control device 5 of the processing tool 1 and the sharpening processing device 100 changes due to the transfer or resale of the processing device 100, the resale or imitation of the processing tool 1, or the control device 5 is updated with another control device. If this happens, both security codes will be different. In this case, authentication by the security code authenticating unit 52 fails, and the ground cutting control data 561 cannot be used for controlling the spindle motor 6 and the tool movement driving device 7 of the ground cutting apparatus 100. Further, as described above, individual identification information for individually identifying each of the sharpening processing apparatus 100 and the processing tool 1 can be set as the security codes # 1 and # 1-1 (= security code # 2). .

  In the example of FIG. 6, the sensor 13 connected to the sensor data transmitter 8 is a temperature sensor that detects the tool temperature of the processing tool 1, but the sensor data transmitter 8 includes only the temperature sensor. Alternatively, a strain sensor, an acceleration sensor, or the like may be connected. In that case, the upper limit value of the management range of strain and acceleration is added to the grinding cutting control data 561 in FIG.

  FIG. 8 is a diagram showing an example of a processing flow of authentication processing of security code # 1 and security code # 2 executed by security code authentication unit 52 (here, security code # 1 and security code # 2). Authentication will be described, and the authentication of security code # 1-1 and security code # 2 will be omitted). This security code authentication process is executed when the control device 5 is powered on or when a machining operation start button or the like is pressed. As shown in FIG. 8, the security code authenticating unit 52 of the control device 5 first acquires the security code # 1 from the field of the security code 852 of the communication frame 85 via the communication frame decomposing unit 51 (step S01). Subsequently, the security code authenticating unit 52 refers to the sharpening control data storage unit with security code 56 and acquires the security code # 2 from the security code 562 field (step S02).

At the same time, since the cooling effect due to the radiation and radiation of heat to the surrounding environment and the propagation to other than the processing site is also taken into account, especially when high-speed processing is performed, there is a variation in the processing quality of the processing part of the workpiece. There was a problem that it was likely to occur. Therefore, in the apparatus disclosed in Patent Document 1, a temperature sensor is placed inside the vicinity of the tip of the tool cut into the workpiece, and the temperature near the tip of the tool close to the temperature of the machining portion of the workpiece. The rotation speed of the tool, the insertion speed into the machining member, or the like is controlled so that the temperature falls within a predetermined management range (processing conditions), or the cooling effect by the cutting fluid is controlled. This makes it possible to reduce variations in the finished quality at the machined part of the workpiece and to measure the precursors of tool breakage, damage, and strong wear in real time, before breakage, breakage, and strong wear occur. In addition, the tool can be changed relatively easily.

Since it is configured, it can be used as an alternative to the tool holder of a general-purpose grinding machine. Therefore, if a system for authenticating the security code is set on the control device side, this measurement / management device can be easily used for a general-purpose grinding machine. As a result, if the control devices are unified, it becomes easy to manage a plurality of sharpening devices simultaneously. The security code on the control device side may be managed and stored as a kind of database information in a storage medium on the Internet.
