Abstract

Computer numerical control (CNC) machines execute a process automatically unless a condition occurs that triggers one or more alarms that terminate the process. Accordingly, CNC laser cutting post-process inspection is usually non-existent or minimal. However, with CNC laser welding it is more common for a visual inspection or automated inspection to be performed to verify that the process was completed. Similar issues occur when single piece parts are required in addition to which executing an offline inspection requires additional complexity in re-working any piece part. Accordingly, embodiments of the invention provide enterprises and facilities employing CNC laser cutting/welding systems with a means to overcome these limitations. Further, providing intuitive user interfaces allows the user to perform tasks directly through a touch screen interface they are viewing the work piece/piece-parts upon.

FIELD OF THE INVENTION

This invention relates to machine tool settings and more particularly to the provisioning of tool instructions directly through a touch screen interface displaying a work piece.

BACKGROUND OF THE INVENTION

Numerical control (NC) is the automation of machine tools that are operated by precisely programmed commands encoded on a storage medium, as opposed to controlled manually via hand wheels or levers, or mechanically automated via cams alone. Most NC today is computer (or computerized) numerical control (CNC), in which local and/or remote computers provide the data files for execution by the machine tool(s). CNC systems allow end-to-end component design to highly automated using computer-aided design (CAD) and computer-aided manufacturing (CAM) programs. The programs produce a computer file that is interpreted to extract the commands needed to operate a particular machine via a post processor, and then loaded into the CNC machines for production.
As a particular component might require the use of a number of different tools, e.g. drills, saws, etc., modern machines often combine multiple tools into a single “cell”. In other installations, a number of different machines are used with an external controller and human or robotic operators move the component from machine to machine. In either case, the series of steps needed to produce any part is highly automated and produces a part that closely matches the original CAD design.
However, CNC machine(s) whilst relying upon the settings of the machine tool or tools required to achieve a specific action with respect to the piece part requires that these actions are pre-programmed so that the CNC machine(s) performs them automatically without supervision. However, in many instances a single simple piece-part is required requiring programming of the piece-part or multiple piece-parts are required whilst only offcuts of material exist such that each piece must be loaded and executed individually. Accordingly, in these instances it would be beneficial for a user to be able to be able to exploit the CNC machine's vision systems and processing capabilities to perform either task.
Further, CNC machine(s) execute a process automatically unless a condition occurs that triggers one or more alarms that terminate the process. With a process such as CNC laser cutting post-process inspection is usually non-existent or minimal. However, with CNC laser welding it is more common for a visual inspection or automated inspection to be performed to verify that the process was completed. As such similar issues occur when single piece parts are required in addition to which executing an offline inspection requires additional complexity in re-working any piece part.
Accordingly, it would be beneficial to provide enterprises and facilities employing CNC laser cutting/welding systems with a means to overcome these limitations. It would be further beneficial if the systems provided intuitive user interfaces allowing the user to perform tasks directly through a touch screen interface they are viewing the work piece/piece-parts upon.
Other aspects and features of the present invention will become apparent to those ordinarily skilled in the art upon review of the following description of specific embodiments of the invention in conjunction with the accompanying figures.

Referring to FIG. 1 there is depicted a network environment 100 within which embodiments of the invention may be employed supporting machine tool systems, applications, and platforms (MTSAPs) according to embodiments of the invention. Such MTSAPs, for example supporting multiple channels and dynamic content. As shown first and second user groups 100A and 100B respectively interface to a telecommunications network 100. Within the representative telecommunication architecture, a remote central exchange 180 communicates with the remainder of a telecommunication service providers network via the network 100 which may include for example long-haul OC-48/OC-192 backbone elements, an OC-48 wide area network (WAN), a Passive Optical Network, and a Wireless Link. The central exchange 180 is connected via the network 100 to local, regional, and international exchanges (not shown for clarity) and therein through network 100 to first and second cellular APs 195A and 195B respectively which provide Wi-Fi cells for first and second user groups 100A and 100B respectively. Also connected to the network 100 are first and second Wi- Fi nodes 110A and 110B, the latter of which being coupled to network 100 via router 105. Second Wi-Fi node 110B is associated with Enterprise 160, such as Ford™ for example, within which other first and second user groups 100A and 100B are disposed. Second user group 100B may also be connected to the network 100 via wired interfaces including, but not limited to, DSL, Dial-Up, DOCSIS, Ethernet, G.hn, ISDN, MoCA, PON, and Power line communication (PLC) which may or may not be routed through a router such as router 105.
Within the cell associated with first AP 110A the first group of users 100A may employ a variety of PEDs including for example, laptop computer 155, portable gaming console 135, tablet computer 140, smartphone 150, cellular telephone 145 as well as portable multimedia player 130. Within the cell associated with second AP 110B are the second group of users 100B which may employ a variety of FEDs including for example gaming console 125, personal computer 115 and wireless/Internet enabled television 120 as well as cable modem 105. First and second cellular APs 195A and 195B respectively provide, for example, cellular GSM (Global System for Mobile Communications) telephony services as well as 3G and 4G evolved services with enhanced data transport support. Second cellular AP 195B provides coverage in the exemplary embodiment to first and second user groups 100A and 100B. Alternatively the first and second user groups 100A and 100B may be geographically disparate and access the network 100 through multiple APs, not shown for clarity, distributed geographically by the network operator or operators. First cellular AP 195A as show provides coverage to first user group 100A and environment 170, which comprises second user group 100B as well as first user group 100A. Accordingly, the first and second user groups 100A and 100B may according to their particular communications interfaces communicate to the network 100 through one or more wireless communications standards such as, for example, IEEE 802.11, IEEE 802.15, IEEE 802.16, IEEE 802.20, UMTS, GSM 850, GSM 900, GSM 1800, GSM 1900, GPRS, ITU-R 5.138, ITU-R 5.150, ITU-R 5.280, and IMT-1000. It would be evident to one skilled in the art that many portable and fixed electronic devices may support multiple wireless protocols simultaneously, such that for example a user may employ GSM services such as telephony and SMS and Wi-Fi/WiMAX data transmission, VOIP and Internet access. Accordingly, portable electronic devices within first user group 100A may form associations either through standards such as IEEE 802.15 and Bluetooth as well in an ad-hoc manner.
Also connected to the network 100 are Social Networks (SOCNETS) 165, first manufacturer 170A, e.g. Linamar™; second manufacturer 170B, e.g. Magna™; steel fabricator 170C, e.g. Supreme Group™; manufacturing solutions provider 170D, e.g. Mayville Engineering Corp.; machine tool manufacturer 175A, e.g. Inovatech Engineering; and online chat/discussion/bulletin board/forum 175B, e.g. Welding Design and Fabrication (http://weldingweb.com/); as well as first and second servers 190A and 190B which together with others, not shown for clarity. Accordingly, a user employing one or more MTSAPs may interact with one or more such providers, enterprises, service providers, retailers, third parties etc. and other users. First and second servers 190A and 190B may host according to embodiments of the inventions multiple services associated with a provider of adult device systems, applications, and platforms (MTSAPs); a provider of a SOCNET or Social Media (SOME) exploiting MTSAP features; a provider of a SOCNET and/or SOME not exploiting MTSAP features; a provider of services to PEDS and/or FEDS; a provider of one or more aspects of wired and/or wireless communications; an Enterprise 160 exploiting MTSAP features; license databases; content databases; image databases; content libraries; customer databases; websites; and software applications for download to or access by FEDs and/or PEDs exploiting and/or hosting MTSAP features. First and second primary content servers 190A and 190B may also host for example other Internet services such as a search engine, financial services, third party applications and other Internet based services.
Accordingly, a user may exploit a PED and/or FED within an Enterprise 160, for example, and access one of the first or second primary content servers 190A and 190B respectively to perform an operation such as accessing/downloading an application which provides MTSAP features according to embodiments of the invention; execute an application already installed providing MTSAP features; execute a web based application providing MTSAP features; or access content. Similarly, a user may undertake such actions or others exploiting embodiments of the invention exploiting a PED or FED within first and second user groups 100A and 100B respectively via one of first and second cellular APs 195A and 195B respectively and first Wi-Fi nodes 110A.
Now referring to FIG. 2 there is depicted a Machine Shop Hub (MASHUB) 204 and network access point 207 supporting MTSAP features according to embodiments of the invention. MASHUB 204 may, for example, be a PED and/or FED and may include additional elements above and beyond those described and depicted. Also depicted within the MASHUB 204 is the protocol architecture as part of a simplified functional diagram of a system 200 that includes an MASHUB 204, such as a smartphone 155, an access point (AP) 206, such as first AP 110, and one or more network devices 207, such as communication servers, streaming media servers, and routers for example such as first and second servers 190A and 190B respectively. Network devices 207 may be coupled to AP 206 via any combination of networks, wired, wireless and/or optical communication links such as discussed above in respect of FIG. 1 as well as directly as indicated. Network devices 207 are coupled to network 100 and therein Social Networks (SOCNETS) 165, first manufacturer 170A, e.g. Linamar™; second manufacturer 170B, e.g. Magna™; steel fabricator 170C, e.g. Supreme Group™; manufacturing solutions provider 170D, e.g. Mayville Engineering Corp.; machine tool manufacturer 175A, e.g. Inovatech Engineering; and online chat/discussion/bulletin board/forum 175B, e.g. Welding Design and Fabrication (http://weldingweb.com/); as well as first and second servers 190A and 190B and Enterprise 160, Ford™.
The MASHUB 204 includes one or more processors 210 and a memory 212 coupled to processor(s) 210. AP 206 also includes one or more processors 211 and a memory 213 coupled to processor(s) 210. A non-exhaustive list of examples for any of processors 210 and 211 includes a central processing unit (CPU), a digital signal processor (DSP), a reduced instruction set computer (RISC), a complex instruction set computer (CISC) and the like. Furthermore, any of processors 210 and 211 may be part of application specific integrated circuits (ASICs) or may be a part of application specific standard products (ASSPs). A non-exhaustive list of examples for memories 212 and 213 includes any combination of the following semiconductor devices such as registers, latches, ROM, EEPROM, flash memory devices, non-volatile random access memory devices (NVRAM), SDRAM, DRAM, double data rate (DDR) memory devices, SRAM, universal serial bus (USB) removable memory, and the like.
MASHUB 204 may include an audio input element 214, for example a microphone, and an audio output element 216, for example, a speaker, coupled to any of processors 210. MASHUB 204 may include a video input element 218, for example, a video camera or camera, and a video output element 220, for example an LCD display, coupled to any of processors 210. MASHUB 204 also includes a keyboard 215 and touchpad 217 which may for example be a physical keyboard and touchpad allowing the user to enter content or select functions within one of more applications 222. Alternatively, the keyboard 215 and touchpad 217 may be predetermined regions of a touch sensitive element forming part of the display within the MASHUB 204. The one or more applications 222 that are typically stored in memory 212 and are executable by any combination of processors 210. MASHUB 204 also includes accelerometer 260 providing three-dimensional motion input to the process 210 and GPS 262 which provides geographical location information to processor 210.
MASHUB 204 includes a protocol stack 224 and AP 206 includes a communication stack 225. Within system 200 protocol stack 224 is shown as IEEE 802.11 protocol stack but alternatively may exploit other protocol stacks such as an Internet Engineering Task Force (IETF) multimedia protocol stack for example. Likewise, AP stack 225 exploits a protocol stack but is not expanded for clarity. Elements of protocol stack 224 and AP stack 225 may be implemented in any combination of software, firmware and/or hardware. Protocol stack 224 includes an IEEE 802.11-compatible PHY module 226 that is coupled to one or more Tx/Rx & Antenna Circuits 228, an IEEE 802.11-compatible MAC module 230 coupled to an IEEE 802.2-compatible LLC module 232. Protocol stack 224 includes a network layer IP module 234, a transport layer User Datagram Protocol (UDP) module 236 and a transport layer Transmission Control Protocol (TCP) module 238. Protocol stack 224 also includes a session layer Real Time Transport Protocol (RTP) module 240, a Session Announcement Protocol (SAP) module 242, a Session Initiation Protocol (SIP) module 244 and a Real Time Streaming Protocol (RTSP) module 246. Protocol stack 224 includes a presentation layer media negotiation module 248, a call control module 250, one or more audio codecs 252 and one or more video codecs 254. Applications 222 may be able to create maintain and/or terminate communication sessions with any of devices 207 by way of AP 206.
Typically, applications 222 may activate any of the SAP, SIP, RTSP, media negotiation and call control modules for that purpose. Typically, information may propagate from the SAP, SIP, RTSP, media negotiation and call control modules to PHY module 226 through TCP module 238, IP module 234, LLC module 232 and MAC module 230. It would be apparent to one skilled in the art that elements of the MASHUB 204 may also be implemented within the AP 206 including but not limited to one or more elements of the protocol stack 224, including for example an IEEE 802.11-compatible PHY module, an IEEE 802.11-compatible MAC module, and an IEEE 802.2-compatible LLC module 232. The AP 206 may additionally include a network layer IP module, a transport layer User Datagram Protocol (UDP) module and a transport layer Transmission Control Protocol (TCP) module as well as a session layer Real Time Transport Protocol (RTP) module, a Session Announcement Protocol (SAP) module, a Session Initiation Protocol (SIP) module and a Real Time Streaming Protocol (RTSP) module, media negotiation module, and a call control module. Portable and fixed MASHUBs represented by MASHUB 204 may include one or more additional wireless or wired interfaces in addition to the depicted IEEE 802.11 interface which may be selected from the group comprising IEEE 802.15, IEEE 802.16, IEEE 802.20, UMTS, GSM 850, GSM 900, GSM 1800, GSM 1900, GPRS, ITU-R 5.138, ITU-R 5.150, ITU-R 5.280, IMT-1000, DSL, Dial-Up, DOCSIS, Ethernet, G.hn, ISDN, MoCA, PON, and Power line communication (PLC).
Also depicted is Machine Tool (MACTO) 270 which is coupled to the MASHUB 204 through a wireless interface between Antenna 272 and Tx/Rx & Antenna Circuits 228 wherein the MASHUB 204 may support, for example, a national wireless standard such as GSM together with one or more local and/or personal area wireless protocols such as IEEE 802.11 a/b/g WiFi, IEEE 802.16 WiMAX, and IEEE 802.15 Bluetooth for example. The Antenna 272 is connected to Processor 274 and therein to Memory 276, Drivers 278, and Features 280. Accordingly, the MACTO 270 may operate as standalone device with factory installed control routines accessed through an interface on the MACTO 270, not shown for clarity, or through an application in execution upon the MASHUB 204. Subsequently, as described below one or more of these control routines may be modified, amended, deleted etc. whilst other new control routines may be created, acquired, installed etc.
Accordingly, it would be evident to one skilled the art that the MACTO 270 with associated MASHUB 204 may accordingly download original software and/or revisions for a variety of functions supported by the drivers 278 and/or features 280. In some embodiments of the invention the functions may not be implemented within the original as sold MACTO 270 and are only activated through a software/firmware revision and/or upgrade either discretely or in combination with a subscription or subscription upgrade for example. Whilst the MASHUB 204, MACTO 270 and AP 206 are depicted exploiting wireless communications it would be evident that in other embodiments of the invention one or more of these wireless communication paths may be replaced with a wired connection or a non-wireless but unwired connection such as an optical link for example or not implemented and communications are through the AP 206 for example between MACTO 270 and MASHUB 204 or even via the network 100.
Now referring to FIG. 3 there are depicted first and second schematics 300A and 300B of plasma cutting machine tool systems as manufactured by Inovatech Engineering which may generate and exploit machine tool settings/configuration profiles as established, verified, and acquired according to embodiments of the invention. Accordingly, each of the plasma cutting machine tool systems in first and second schematics 300A and 300B may be an example of a MACTO 270 in FIG. 2. Considering initially first schematic 300A then:

- Robot enclosure 310, provides an environment containing fumes, reducing noise etc.;
- Cross-transfer 320, allows different load/unload profiles to be employed as well as materials receipt/processed material delivery, etc. and saves time;
- Plate table 330, provides base for sheet/plate as moved relative to plasma cutter where typical configurations include 6″×10″ (2 m×3 m), 12′×10′ (4 m×3 m), and 24′×10″ (8 m×3 m);
- Operator station 340, wherein an industrial computer controls plasma robot, conveyors, plate table, etc. and displays messages, alarms, maintenance screens, plasma control settings etc.;
- Infeed/outfeed conveyors 350; chain or belt driven conveyors allow material to be received from stock/prior MACTO 270 and/or transferred to finished stock/next MACTO 270.
- Ventilation system 360, which provides automatic fume extraction and filtering etc.; and
- Plasma gas control etc. 370, with automated gas control etc. for different cutting processes adapted to plasma cutter head, material processed, etc.

Now referring to second schematic 300B then:

- Plasma gas control etc. 3010, with automated gas control etc. for different cutting processes adapted to plasma cutter head, material processed, etc.
- 6-axis robot 3020, with plasma cutter head allowing control over head position, orientation and movement of plasma cutter head relative to the piece part independent of any motion of the piece part which as depicted is within an enclosure that moves along the profile table 3040 reducing overall space requirements;
- Water 3030, optionally inserted in line for quenching, cutting stiffener plates, etc.;
- Profile table 3040 which supports the piece-part(s) and allows for laser piece-part scanning and alignment of the piece-part on the profile table; and
- Operator station 3050, wherein an industrial computer controls plasma robot, conveyors, plate table, etc. and displays messages, alarms, maintenance screens, plasma control settings etc.

Accordingly, the operator stations 340 and 3050 in first and second schematics 300A and 300B (hereinafter operator station), acting for example as MACTO 270 with optional communications to a central machine shop system, e.g. MASHUB 204, or acting a MASHUB 204 in a stand-alone configuration provides the required control settings to the computer controlled elements of the plasma cutting machine tool system such as robot (not shown for clarity), plasma cutting tool, and plate table for example. These may be selected from a menu of control setting profiles defined, for example, by product name/product serial number etc. stored upon the operator station or alternatively the operator station retrieves the control setting profile from a remote system such as MASHUB 204. Accordingly, when the operator triggers execution of a machine tool profile (MACPRO) that defines the control settings of the plasma cutting system, in this instance although it would be evident that the MACTO 270 may be any other machine tool accepting computer numerical control (CNC) etc., together with the motion sequence of the robot and plate table as well as in other instances cross-transfer 320, infeed/outfeed conveyors 350, profile table 3050, etc.
Laser welding systems operate through conduction welding or penetration laser welding. Conduction welding is performed at lower energy levels resulting in a wide and shallow weld nugget through either direct heating or absorption. In direct heat welding the heat flow within the work piece is governed by classical thermal conduction from the surface heat of the absorbed laser such that the weld is made by melting portions of the base material. This can be performed on a wide range of alloys and metals. In absorption welding energy is absorbed through inter-facial absorption wherein an absorbing ink is placed at the interface of a lap joint which absorbs the laser beam energy. This is then conducted into a limited thickness of the surrounding material to form a molten inter-facial film that solidifies as the welded joint. Butt welds can be made by directing the energy towards the joint line at an angle through material at one side of the joint, or from one end if the material is highly transmissive.
In contrast conduction-penetration welding occurs at medium energy density and results in further penetration of the weld into the material. Finally, keyhole mode welding creates a deep narrow weld within the material as the laser forms a filament of vaporized material known as a “keyhole” that extends into the material and provides a conduit for the laser energy to be efficiently delivered into the material. This direct delivery of energy into the material does not rely on conduction to achieve penetration, so it minimizes the heat into the material and reduces the heat affected zone.
Referring to FIG. 4 there is depicted a schematic diagram 400 of a welding-inspection sequence upon a CNC laser welding system 410 according to an embodiment of the invention. As depicted the CNC laser welding system (CNC-LWS) 410 incorporates a 6-axis robot (6AX-R) 3020 coupled to a computer 450 and therein to the network 100. Accordingly, the user has selected to weld a piece-part 430 wherein the 6AX-R 3020 in conjunction with the table/platform upon which the piece-part 430 is mounted. Accordingly, in process 420 the CNC-LWS 410 executes the sequence of stage and welding movements as the laser welds the components 425 to form the piece-part 430. Subsequently, the CNC-LWS 410 executes an inspection sequence 440, quality control (QC), wherein the stage and welding movements are repeated but now the system directs its camera to acquire images of the welds which are depicted in first to fourth images 460A to 460D. These images may then be stored within a database in association with an identifier of the piece-part, which may be uniquely generated by the CNC-LWS 410 and cut into it during the welding process. These images and processing data for the piece-part may be locally stored or remotely stored on a remote server connected to the network 100.
Alternatively, as depicted in FIG. 5 in schematic diagram 500 of a welding-inspection sequence upon a CNC-LWS 510 according to an embodiment of the invention with third party interfaces to manufacturer 550, e.g. Ford™, and CNC-LWS manufacturer 560, e.g. Inovatech Engineering Corp. During a QC process 520 similar to that described and depicted in respect of inspection sequence 440 a defective weld is detected in first image 540A wherein the user has captured the image during a manual inspection sequence as the piece-part is traversed by the 6AX-R 3020 and the camera attached to it. Optionally, the images may have been automatically captured during inspection sequence 440 wherein the images have been image processed allowing determination of defects. Accordingly, the user may select a re-work option within the menu presented to the user on the CNC-LWS 510 wherein a subsequent image 540B is captured.
Optionally, the originally acquired images of the weld(s) may be transmitted to either the manufacturer 550 as the consumer of the piece-part who may accept or reject the part wherein a rejection triggers the re-work of the piece-part. Optionally, the user may select an advice option that transmits data relating to the weld(s) to the CNC-LWS manufacturer 560 wherein they may provide data to the user allowing them to re-work the piece-part and/or adjust the settings of the CNC-LWS 510. Optionally, the advice option may push data relating to the piece-part materials, processing parameters, images etc. to a CNC-LWS user community or alternatively the user may be part of an online community wherein enhancements to processes are submitted by users for verification by the CNC-LWS manufacturer 560, wherein these are then pushed to users as part of upgraded operating processes. Accordingly, the methodologies and concepts described by the inventors within U.S. Provisional Patent Application 62/218,611 entitled “Client Initiated Vendor Verified Tool Setting” filed Sep. 15, 2015 may be employed and/or extended to include requests for advice, requests for settings etc.
Optionally, the user may be presented with images acquired of the piece-part and through indication of one or more locations on the piece-part additional welds may be added to those already implemented on the piece-part. Optionally, the user may be presented with images associated with the piece-part to be welded together with indications of welds to be performed wherein the user may through indication of one or more locations add additional welds to the process to be performed.
Now referring to FIG. 6 there is depicted a schematic diagram 600 of an intuitive user interface for a user to perform one-off processes with a CNC plasma cutting system according to an embodiment of the invention. As depicted a CNC plasma cutting system (CNC-PCS) 610 is depicted comprising a controller 450 in conjunction with a 6AX-R 3020 and other elements such as depicted in respect of FIG. 3 in respect of first and second schematics 300A and 300B. Accordingly, the user is performing a cut yielding first configuration screen 620 if they select to define a cut (select “Free Cut”) and second configuration screen 660 if they select additional shape definition (select “Shape Cut”). In first configuration screen 620 the user is presented an image of the CNC-PCS 610 table in its current position relative to the 6X-R 3020. Upon the image are displayed outlines 650 of piece parts either previously cut or about to be cut from the sheet within the CNC-PCS 610. The user can now through selecting the “Define” button draw an additional cut 640 which is either executed at that point if the parts defined by the outlines 650 have already been cut or it is added to the cutting sequence for execution once the outlines 650 are processed during the cutting sequence to be executed.
In second configuration 660 the user is similarly presented with an image within which are displayed outlines 650 of piece parts either previously cut or about to be cut from the sheet within the CNC-PCS 610. The user is then able through “Free” or “Library” to define an additional element 670 to be cut from the sheet. In “Free” the user can draw freehand a piece part with or without a guide grid to which their motions may or may not be snapped. Alternatively, in “Library” they may select a piece-part from a list of piece-parts which once selected may be translated and/or rotated to provide a suitable fit to the offcut or remaining portion wherein if confirmed, through a subsequent menu or pop-up menu not depicted for clarity, is then either cut at that point or it is added to the cutting sequence for execution once the outlines 650 are processed during the cutting sequence to be executed. Optionally, the CNC-PCS 610 may, through knowledge of the camera system, 6AX-R 3020 position etc. calculate the dimensions of the field of view and therefrom define dimensions of the off-cut or unassigned portion of the sheet to be cut. Based upon these the piece-parts listed to the user may be pre-filtered for the available footprint of the sheet. They may also be filtered based upon other characteristics of the sheet being cut such as material and thickness that are associated with the piece-parts such that only those matching the currently loaded material/thickness etc. are displayed to the user. In the event that the user loads an offcut without any associated cutting sequence of other parts then the system upon detecting this event requests that the user provide this data either as part of an earlier processing step or in conjunction with these steps.
Now referring to FIG. 7 there are depicted first to eighth images 710 to 780 in respect of an image inspection stitching sequence for a CNC laser cutting system according to an embodiment of the invention. Within the preceding description with respect to FIGS. 4 to 6 the CNC laser cutting system according to an embodiment of the invention presents the user with image data relating to the piece part being processed and/or processed as well as computer generated piece-part overlay(s). However, it would be evident that these images may represent only a portion of the work piece and/or the CNC laser cutting project. Accordingly, first to eighth images 710 to 780 depict:

- First image 710 depicts a work project overlay 705 to CNC laser cutting application in execution upon the CNC laser cutting system;
- Second image 720 depicts the work project overlay indicating the piece-parts within the current work project together with region 725 which the user has identified which is then imaged in a series of steps;
- Third image 730 depicts the work project overlay together with the first four acquired images from the CNC laser cutting system camera that are stitched together in order to generate the overall image as the camera does not in combination with the cutting robot provide the ability to image the entire work piece and/or the entire work project within the work piece;
- Fourth image 740 depicts the acquired stitched images once completed for the region 725;
- Fifth and sixth image 750 and 760 depict the extension of the acquired images and their stitching to the fourth image 740 as the user has established a command sequence for extended imaging;
- Seventh image 770 depicts the acquired stitched image together with the work project overlay but also that the user has selected a specific element 775 within the work project overlay' and
- Eighth image 780 wherein the user is moving the work project overlay relative to the acquired stitched image of the work piece such that the user can establish a work piece/work project overlay allowing a piece-part or piece-parts to be processed (cut) from the work piece.

Accordingly, the system establishes an automatically stitched image of the work piece against which a user can manipulate a work piece overlay allowing a piece-part or piece-parts to be cut from a work piece without an extensive complex set-up process. Accordingly, by exploiting an image stitching process for the robot camera not only can multiple piece-parts be placed and orientated against a work piece but large piece-part(s) and work pieces can be visualized without the limitation that the entire work piece and/or piece-part fit within the field of view of the robotic camera. Within embodiments of the invention the robotic camera may be the same camera as visualizes during the CNC machine processes or it may alternatively be a second camera with different optical characteristics referenced to the CNC robot or to the CNC system overall.
Now referring to FIG. 8 there are depicted first and second screenshots 800A and 800B of an intuitive user interface for a user to perform one-off processes with a CNC laser cutting system according to an embodiment of the invention. As discussed supra in respect of FIG. 6 a user may exploit a touch-screen interface to perform one-off processing such as cutting a piece from a sheet, adding a weld, etc. As depicted in FIG. 6 in first configuration screen 620 the user can define a cut through the touch-screen (by selecting “Free Cut”) and in second configuration screen 660 they can select predetermined shapes (by selecting “Shape Cut”) which they can manipulate and add to, e.g. adding holes, slots, etc. However, it would be evident that the user may use a different haptic interface other than the touch screen of the machine such as a keyboard, computer mouse, etc. or a touch screen and/or another haptic interface interfaced to the machine directly or subsequently. Hence, a user may be standing away from the machine using a stylus on a tablet PC wirelessly connected to the machine to draw the piece-part where the image on the machine screen is also presented to the user on the other electronic device.
However, alternatively, the user may directly mark the workpiece with a marking material, e.g. chalk, ink, paint, etc. that is captured by the machine's imaging system and processed to generate the instructions for the machine. Accordingly, in first image 800A the display is depicted in image acquisition mode wherein the work piece 850 is depicted with traces for previously cut or to be cut piece-parts. Accordingly, there is depicted an outline 830 comprised of freehand marked lines 820 and a curve 810, the curve including an indicator 815 also marked by the user. Subsequently, as depicted in second image 800B the machine processes the outline 830 to generate profile 840 wherein the freehand lines 810 are replaced with fitted lines based upon each individual line and the overall combination of lines marked and the curve 810 generated based upon association of the indicator 815 with the curve 810 as otherwise the image processing may replace it with straight line segments. Whilst the indicator 815 is depicted as a “C” it would be evident that other markings may be employed, e.g. “▴”, to indicate that the freehand element is of a specific type. It would be evident that a range of standard markings may be established to indicate specific functions and that these may vary according to the function of the CNC system such that markings for a laser or plasma cutting system are different to those of a welding system or a drill press.
Within other embodiments of the invention in order to avoid other markings make to work pieces being interpreted, e.g. chalk markings made as part of stock management, inventory control, previous processing etc., that the CNC system may interpret markings of a specific colour, e.g. yellow or red versus white. The CNC system may provide a colour for the work piece to be marked in or the user enters it based upon colours available that are different to any markings already on the work piece. Other colours may be ignored irrespective of user selection so that confusion with aspect of the work piece are considered based upon a material selection as part of the overall process. For example, steel may mean red/orange are ignored automatically so that rust does not impact the determination of cut lines for example or placement of holes etc. Similarly, cutting blue anodized aluminum means all blue-green colours are ignored. Other variants and variations may be considered. For marking large work pieces, the CNC system may interpret a series of discrete lines with or without associated indicators as a continuous line.
Optionally, a template of the piece-part to be cut may exist, e.g. from a previous processing, from a template provided, etc. For example, a wooden or plastic template may have been formed by a customer at a worksite. Accordingly, its image may be captured upon the work-piece or discretely, processed, and then the pattern employed upon the CNC machine.
Now referring to FIGS. 9A and 9B there are depict first to fourth schematic images 900A to 900D respectively of an intuitive user interface for a user to perform part selection and manipulation for one-off processes with a CNC laser cutting system according to an embodiment of the invention. Accordingly, as depicted in first schematic image 900A the user is presented with an image 910 within which are depicted outlines 920 of piece-part(s) to be processed and/or already processed and has selected within the menu the option “Define” in order to select a piece-part to process Next in second schematic image 900B the user has selected within a pop-up window 930A, such as through one or more menus as known in the art, a template file comprising a plurality of piece-parts 940. Subsequently in third schematic image 900C the user has within the pop-up window 930B selected a single piece-part 940 and rotated it to rotated part 950. Subsequently, as depicted in fourth schematic image 900D the user has finished selecting and adjusting the piece-parts depicted as first and second parts 960 and 970 respectively.
Accordingly, the user is able to directly access templates to select piece-parts, manipulate them individually or in groups or in their entirety wherein these are then directly processed by the CNC machine. In this manner a user may rapidly and easily establish a single piece-part to process or establish and process multiple piece-parts upon a new work piece or upon a previously used work piece in order to reduce waste etc. The manipulations available to a user may be limited, for example, to translations and rotations in order to fit the piece-part to a work-piece such as depicted with first part 960. In other embodiments the user may be able to scale a piece-part in conjunction with other transformations as well as combine them with others, replicate, copy, paste etc. Hence, for example, the user may add bolt holes to first and second piece parts 960 and 970 respectively or overlap them wherein the combined profile is processed. Whilst the embodiments of the invention have been described through the user accessing templates and accordingly piece-parts codes with a descriptor language compatible with the numerical control (NC) systems, e.g. G-code (RS274), the piece-part may be imported from a non-NC format such as a drawing file (e.g. .DWG, DXF) or image file (e.g. JPEG, TIFF etc.).
Whilst the discussions presented supra in respect of FIGS. 1 to 9B have been primarily presented with respect to settings of laser welding and plasma cutting systems. However, it would be apparent to one of skill in the art that the methodologies may alternatively be associated with a tool rather than the machine or with respect to a consumable of a tool and/or machine. Further, these processes and methodologies may also be applied to range of other manufacturing processes and/or machines including, but not limited to, machining, milling, welding, cutting, forming, welding, and 3D printing with processes exploiting additive and/or removal processes such as plasma, laser, thermal, fluid etc.
For example, a user may access a template for welding a bracket and may manipulate the location(s) of weld(s) as well as adding/removing welds or modifying the length of a weld. In each instance that a user modifies an existing template the modified template may be stored as a new template. Within other embodiments of the invention the user may simply denote a location of a weld and the CNC system will execute a predetermined weld sequence established in dependence upon the piece-parts being welded as established, for example, by material, thickness, angle of piece-parts etc. Hence, the user may only define a spot or a line and the remainder is performed using the best process established by the CNC machine from its library and/or external libraries. In other instances, the CNC machine may communicate a request for a process to the manufacturer or a user community. Within embodiments of the invention standard process libraries may be updated such as described by the inventor within U.S. Provisional Patent Application 62/218,611 entitled “Client Initiated Vendor Verified Tool Setting.”
