Description

  The present invention relates to a machining operation management support system and a machining operation management support method that can be applied particularly when machining operations are performed using an NC machine tool.

  NC machine tools are increasingly automated. However, when it is necessary to change the mounting position or mounting direction of the workpiece (workpiece) or when it is necessary to replace the workpiece itself, the worker performs the work manually on the machine tool. There is a need. As described above, an operation in which an operator prepares for the next processing on the machine tool is sometimes referred to as “setup”.

  However, when the setup work is performed, since the worker works on the machine tool, the operation of the machine tool must be stopped. For this reason, it is not possible to proceed with the machining work during the work period.

  In addition, recent NC machine tools can also automatically change tools. However, it is only necessary that an operator removes a necessary tool from a storage location in advance and places the tool in a predetermined position on the machine tool. It is necessary to set. In this case, the operator often mistakenly prepared a tool different from the tool that should originally be prepared, so that correct machining was often not performed.

  Until now, rigorous management has not been done for the insertion and removal of tools, and there were places left up to the operator, so it often happened that tools were lost or stored in the wrong place.

  Furthermore, since the management of the workpiece that has been started is entrusted to the operator, the workpiece in the middle of machining is lost while it is removed from one machine tool and attached to another machine tool, and machining work is started from the beginning. There was often waste of work that had to be done.

  The present invention has been made on the basis of such a background, and it is possible to appropriately manage tools and workpieces, and to ensure that work tool management support systems capable of reliably avoiding tool loss, tool attachment errors, workpiece loss, etc. An object is to provide a processing work management support method.

  In order to solve the above-described problems, a machining operation management support system according to the present invention provides a machine tool with a predetermined unit machining operation to a worker based on computer-handled data obtained in a design department. Necessary tool teaching means for teaching individual tools to be used and necessary tool confirmation means for confirming that the operator has prepared each tool taught by the necessary tool teaching means are provided.

  Thereby, a tool required for unit machining work can be prepared with certainty, and errors can be reduced. Furthermore, by providing the tool return confirmation means for confirming that the individual tools taught by the necessary tool teaching means are returned after the machining operation is completed, it is possible to reliably prevent the tool from being lost.

  The machining operation management support system according to the present invention includes a necessary workpiece teaching means for teaching a worker a workpiece required for a predetermined unit machining operation, and the necessary workpiece teaching means. Based on the necessary work confirming means for confirming that the worker has prepared the taught work and the data that can be handled by the computer obtained by the design department, the predetermined unit machining work is given to the worker. Based on the necessary jig teaching means that teaches the jigs required for the machine and the computer-handled data obtained in the design department, the machining set presentation that presents the operator with an image of the machining set to be created Means.

  Thereby, even a worker who has little work experience can surely prepare a workpiece necessary for unit machining work, and can quickly and surely prepare a machining set described later. Furthermore, the processing set can be reliably managed by providing the processing set return confirmation means for confirming that the processing set has been returned after the processing operation is completed.

  Furthermore, the machining operation management support system according to the present invention teaches an individual tool to be used with a machine tool for a predetermined unit machining operation to a worker based on computer-handleable data obtained in the design department. Necessary tool teaching means, necessary workpiece teaching means for teaching an operator a workpiece required for the predetermined unit machining operation, and workpiece taught by the necessary workpiece teaching means Necessary workpiece confirmation means for confirming that the operator has prepared the workpiece and the computer-acquired data obtained in the design department are required for the operator to perform the predetermined unit machining operation. Based on necessary jig teaching means for teaching jigs and computer-handled data obtained in the design department, an image of the machining set to be created for the operator A processing set presenting means presenting, each tool taught by the necessary tool teaching means may be provided and the required tool confirmation means for confirming that the operator has prepared. In addition, tool return confirmation means for confirming that the individual tools taught by the necessary tool teaching means have been returned after the machining work has been completed, and that the machining set has been returned after the machining work has been completed. It is also possible to provide a processing set return confirmation means for confirming.

  In the above-described machining operation management support system, further, RFID identification means for individually identifying each of the tools and / or RFID identification means for individually identifying each of the machining sets are provided, and the necessary tool confirmation is performed. The means and / or the processing set return confirmation means performs confirmation work using the RFID identification means. Thereby, confirmation work can be performed quickly and reliably.

  Furthermore, when it is necessary to temporarily store a tool set consisting of individual tools taught by the necessary tool teaching means, a tool storage location instruction means for instructing the operator of the storage location can be provided. Further, when the processing set is created, when it is necessary to temporarily store the processing set, a processing set storage location instruction means for instructing the operator of the storage location can be provided.

  Further, the machining operation management support method according to the present invention uses a computer to individually use a machine tool for a predetermined unit machining operation for an operator based on computer-handleable data obtained in a design department. Necessary tool teaching process for teaching a certain tool, Necessary workpiece teaching process for teaching a workpiece required for a predetermined unit machining operation to an operator, and computer handling obtained in the design department Based on the data, a machining set presentation process for presenting an image of a machining set to be created to the operator, and a necessary tool check for confirming that the operator has prepared each tool taught in the necessary tool display process. And execute the process. Further, using a computer, a tool return confirmation step for confirming that the individual tools taught by the necessary tool teaching means are returned after the machining work on the machine tool is completed, and a machining work on the machine tool. It is desirable to execute a machining set return confirmation step for confirming that the machining set has been returned after the process is completed.

  According to the present invention, the operator is assured that the individual tool used in the NC machine tool is taught to the operator for a predetermined unit machining operation (for example, an operation that can be performed by one setup). This makes it possible to prepare the necessary tools for avoiding the possibility of preparing an incorrect tool.

  Further, by teaching the work piece required for the worker, the worker can prepare a correct work piece. Also, by teaching the machining set to be created to the worker, even an inexperienced worker can easily prepare the machining set, and the worker can create the machining set away from the machine tool. Therefore, it is not necessary to stop the operation of the machine tool during that time, and work efficiency is improved.

  In addition, by confirming that each tool has been prepared by the operator and confirming that each tool has been returned after the machining operation on the machine tool has been completed, the tool has been lost. Or store it in the wrong place can be reliably prevented.

  FIG. 1 is a diagram showing an outline of a computer system for performing operations from designing a certain product to making a mold for manufacturing the product. This figure also shows the flow of work steps from product design to mold machining.

  Here, in the case of “product”, it is limited to a product that can be manufactured by molding, such as a casing of a mobile phone. There are also many cases such as an upper case, a lower case, a battery case cover case, a case around a liquid crystal window, etc., and each of them corresponds to a “product” here. For each product, a mold is required to mold it.

  In FIG. 1, product design software 100 is software that supports a product designer to design a product on a computer. Typical product design software is so-called CAD (Computer Aided Design) software.

  The mold design software 200 is software for designing a mold for molding the product based on the product design data obtained by the product design software 100. The mold design includes various factors such as the shrinkage ratio of the resin, where the upper and lower molds are divided, what mold parts are used, and where the ejector pins are arranged.

  The NC data creation software 300 is software that creates NC data for automatically machining a workpiece (workpiece) to be a mold with a machine tool based on the data obtained by the mold design software 200 and data associated therewith. is there. The accompanying data includes information on what tools are used when executing the automatic machining, and information for displaying the finished state of a “machining set” described later in a three-dimensional manner with the viewer software.

  Product design software 100, mold design software 200, and NC data creation software 300 are mainly executed on a computer in a design department.

  Data created by the NC data creation software 300 is sent to the factory department. In the system of the present embodiment, as shown in FIG. 1, work delivery management software 400, setup management software 500, and machine tool control software 600 are provided in a factory department. Among these, the work delivery management software 400 and the setup management software 500 are software installed in a general-purpose computer in a factory department, and the machine tool control software 600 is software installed in a computer that controls a machine tool.

  The product design software 100, the mold design software 200, the NC data creation software 300, the work delivery management software 400, the setup management software 500, and the machine tool control software 600 are connected to each other via a dedicated network line. Further, a process management software 700 for managing all processes from product design to mold formation is also connected to the network line. The database 800 is a database in which various pieces of information necessary for product design and mold design are accumulated. When each person in charge uses the above software, the computer 800 can connect from each computer via a network. The necessary data which is referred to and stored therein is retrieved or newly written.

  The main part of the present invention is mainly related to the work delivery management software 400 and the setup management software 500 in the factory among the steps shown in FIG. When the person in charge of NC data creation finishes creating the NC data, the obtained NC data and the accompanying data are sent to the computer in the factory department. Based on this, the process management software 700 causes the work delivery management software 400 and the setup management software 500 to generate a predetermined task to be performed by the worker. In the following, the terms “K2 NAVI” and “K2 Pharmacy” appear, but the former is the name used in the factory department of the work delivery management software 400 and the latter is the setup management software 500.

  As described above, K2 NAVI is software that manages the delivery status of a work (work before processing) for making mold parts. If the workpiece is just purchased and received in the storage shelf, the individual workpieces are not yet identified. However, in this embodiment, after the workpieces are issued from the storage shelf, where the workpiece is and what Sequentially track the situation. As a means for that purpose, in this embodiment, an identification system including an RFID (Radio Frequency IDentification) tag and an RF reader / writer is used.

  Embedded in the RFID tag is an integrated circuit chip in which a coil for transmitting and receiving electromagnetic wave signals, an electronic circuit for signal processing, and a nonvolatile memory for storing data are integrated. Since an RFID tag uses an electromotive force generated by electromagnetic induction between an electromagnetic wave sent from an RF reader / writer (not shown) and the coil as a power source, it is not necessary to have a power source in itself. Information can be written to and read from an RFID tag in a contactless manner via an RF reader / writer.

  In the present embodiment, the RFID tag is also lent to each person in charge in order to individually identify the person in charge at the factory. For this reason, the person in charge is required to always carry his / her RFID tag. Further, as will be described later, this RFID tag is also attached to each tool, a tool set composed of each tool, and a machining set to identify each tool individually. In the factory where this system is installed, readers / writers for RFID tags are installed at necessary places, and these are connected to the above-mentioned process management software 700 via a computer connected to the network. ing.

  FIG. 2 is a screen displayed when K2 NAVI is started up. When the person in charge who wants to use K2 NAVI enters a predetermined LOGIN ID on this login screen and clicks the LOGIN button, K2 NAVI is launched. When K2 NAVI starts up, it first displays a list of stored shipping tasks.

  FIG. 3 is a task list screen displayed on the K2 NAVI terminal. This task is a list of tasks for issuing a workpiece. In other words, this is also a list of work that must be issued. Even if there is only one order, there are a plurality of tasks if there are a plurality of parts of the type corresponding to the order, and there can be many orders themselves, so the number of tasks is the number corresponding to that. The task list shown in FIG. 3 is created based on information supplied from the process management software 700 of FIG.

  The person in charge of the work starts K2 NAVI, and if there is a task in the task list of FIG. The specific procedure for the delivery operation is as follows.

  The worker selects and double-clicks a task to be executed on the task list screen of FIG. Then, when the type of the selected task type is mold, core, or plate, the screen shown in FIG. 4 is displayed. If the selected task type is a slide within the standard, the screen shown in FIG. 6 will be displayed. If the selected task type is a non-standard slide, the screen will be described later. When the selected task type is Spring Core, the screen shown in FIG. 12 described later is displayed.

  In the task list screen of FIG. 3, when the type of the selected task type is core, the screen of FIG. 4 is displayed. Note that the same screen as in FIG. 4 also appears when the type of the selected task type is mold or plate.

  In the screen of FIG. 4, the operator first confirms the column “part number” indicated by the circled number 1. In the example of FIG. 4, “CORE 01” is displayed in the column “part number”. In the column “check item” below, work items that the worker must execute are displayed, and the worker performs work according to this instruction. According to this display, the worker first picks up a predetermined workpiece (workpiece) (in this case, CORE 01) from a predetermined place where it is stored after purchase. Then, click the left square (indicated by the number 2 with a circle) on the left side of “Extract Work” on the screen to add a check mark. At this stage, the workpieces are not yet individually identified.

  Subsequently, the worker attaches the RFID tag to the work as written in the second column of “check item”. The tag to be pasted here has nothing written yet. When the tag is pasted, place a check mark in the second square (indicated by the circled number 3). Next, hit the RF reader / writer near the pasted tag and click the third square (indicated by a circled number 4). Then, writing of necessary information to the RFID tag is started. Here, necessary information including information such as what kind of workpiece is used and which part of which order number is used is written. Thereby, after this, this work is specified individually. When writing is completed, a message to that effect is displayed.

  Subsequently, the operator checks “Ready” in the “Status” portion of the screen of FIG. 4 and presses the “Send” button (indicated by a circled number 5). Then, the screen shown in FIG. 5 appears. Click “Yes”. This completes the work delivery work for “CORE 01”.

  As described above, when the work to be delivered is a slide within the standard, the screen of FIG. 6 is first displayed. In the case of a slide, since there is a circumstance that the work must be cut to the length to be used, it is handled differently from the mold or the like in order to confirm the dimensions. As one of them, a button called “BOM” (indicated by a circled number 2) can be pressed on the display screen of FIG. 6, and when this button is pressed, a tree is displayed as shown on the left side of FIG. The bill of materials is displayed in the display. When the corresponding part name (here, the circled number 7) is clicked on this screen, the corresponding screen is displayed on the right side of the display as shown in FIG. Here, various pieces of information about the work are included, and among them, the worker confirms the size of the work indicated by the circled numeral 8 in particular.

  When the confirmation is completed, an “end” button (indicated by a circled number 9) in the upper right of FIG. 8 is clicked to return to the screen of FIG. Then, the FRID tag is pasted in the same manner as the above-mentioned cabinet and the like. In this case, since the size is small, it is not pasted directly, but pasted on a dedicated case, and information is written with an RF reader / writer. Then, the work is accommodated in this case. Then, the “Yes” button is clicked on the screen of FIG.

  By attaching an RFID to a work that has been delivered in this manner, it is possible to reliably track the status of each work using an RF reader / writer and a computer. The delivered workpiece is stored in a predetermined storage location until a workpiece set described later is created using this workpiece. K2 NAVI instructs the worker where to store it, and the worker stores it in a predetermined place according to the instruction.

  As mentioned above, in the work delivery work, all the workers in charge of work need only work according to the instructions displayed on the K2 NAVI screen on the computer terminal, so the work is very easy and not a skilled worker. But there is very little room for mistakes.

  When the writing to the RFID tag is finished, the exit task end screen shown in FIG. 5 is displayed. The transmission of the task shown in FIG. 5 means that the task that must be performed by the worker is transferred to the process management software 700 thereafter. Therefore, the transmission of this task is the end of the outgoing task in K2 NAVI. When the worker clicks “Yes”, the shipping task in K2 NAVI ends.

  As described above, the unstandardized slide unloading process is shown in FIGS. 9 to 11 and the spring core unloading process is shown in FIGS. 12 to 14. However, the process to be performed by the operator is almost the same as described above. Therefore, explanation is omitted here.

  When the workpiece is delivered, the machining operation can be performed on the workpiece. The process management software 700 recognizes this and first generates a tool set creation task for K2 Pharmacy. Here, the “tool set” is a group of a plurality of tools necessary for processing a specific workpiece with a single setup. “Creating a tool set” means preparing such a tool set in one container in advance. One of the features of the present embodiment is that these items are prepared in advance according to instructions from the computer.

  In addition to the so-called NC data, the data sent from the NC data creation software 300 to the factory computer also accompanies data on what kind of tool is used when the machine tool tries to process a certain path for the workpiece. I'm allowed. When the factory department computer receives this data, the process management software 700 generates a “tool set creation” task in K2 Pharmacy. K2 Pharmacy recognizes the necessary tools by referring to the tool data attached to the NC data.

  FIG. 15 is a screen of the task list of K2 Pharmacy. The task list screen in FIG. 15 displays a list of tasks that the operator must execute under the management of K2 Pharmacy. In this example, two tasks "Create tool set" are displayed.

  The tool set is created as follows. When the tool set creation task below the two displayed on the screen of FIG. 15 is selected and double-clicked, the screen shown in FIG. 16 is displayed. The worker performs the work in accordance with the instructions displayed in the area indicated by reference numeral 20 on this screen. In FIG. 16, an instruction “read operator TAG” is displayed in this area. Therefore, the operator causes his / her RFID tag to be read by an RF reader / writer in order to inform the system that he / she is authorized. K2 Pharmacy performs the authentication work on the read ID, and permits the continuation of the subsequent work only when the worker has a valid authority registered in advance. At the same time, the operator and the work content (which tool was taken out) are recorded.

  When an actual tool set creation operation is started, first, K2 Pharmacy displays the number of the tool to be taken out from the storage location (number “No CD080210J06” in this case) in the area 22 of FIG. In this case, it is also displayed that this tool is the first of a set of six in total. Each tool is put in a case one by one, and each case is provided with an RFID tag for identifying the tool. Therefore, when the operator takes out a predetermined tool (actually a case where the tool is put) from the storage place, the RFID tag is read. Then, a check mark is automatically added to the left square of the tool displayed in the area indicated by the circled number 3 in FIG. In the same manner for the second and subsequent tools, the same operation is performed every time the operator picks up the tool from the storage location. When all six tools are prepared, one tool set is completed. In this case, if a different tool is issued when the specified tool is issued, the RFID tag is read and a warning is issued by K2 Pharmacy that "Tool ID is different".

  Note that when creating a tool set, a rule is set so that the operator does not take out the tool from the case. Also, after the machining set is created, when the operator actually attaches the tool to the machine tool, the information is read from the RFID tag one by one according to the instructions of the computer, and the tool is attached from the machine tool to which the tool should be attached. Is instructed to remove, and the removal work will be performed accordingly. For this reason, a one-to-one relationship is always maintained between each tool and the RFID that identifies each tool.

  When removing a tool from a predetermined storage location, attaching the tool to the machine tool, removing the tool from the machine tool, and returning the tool to the storage location, the operator must read the RFID tag of the tool. By doing this, K2 Pharmacy has a complete picture of what each tool is in.

  In the circled number 3 in FIG. 17, when six tools are prepared, the tool set creation task ends, and therefore one tool set creation task disappears as shown in FIG. 18. In this way, by dismissing completed tasks from the screen and displaying only those tasks that have not yet been completed, the operator can see the display on the terminal at a glance, but what tasks must be done? You can see if there is something wrong.

  When one tool set creation task is completed in this way, the created tool set is temporarily stored in a predetermined storage location designated by K2 Pharmacy. In this case, in the system of the present embodiment, a lamp that can emit various colors is provided on a shelf to be stored. At the same time, a lamp of a predetermined color on the shelf which is the storage location is turned on, so that the operator can immediately know the shelf to be stored. When an operator stores a tool set on the shelf and enters information indicating that the storage has been completed in K2 Pharmacy, the shelf lamp also turns off at the same time. Even when a tool set or a machining set described later is taken out from the shelf, when the computer instructs the operator where to place the shelf, a lamp of a predetermined color on the shelf is turned on at the same time.

  For a tool set created, a “machining set creation task” for creating a machining set to be machined with the tool is generated.

  When a workpiece is machined with a machine tool, the orientation and height of the workpiece to be mounted on the machine tool is different for each operation so far, and a skilled worker considers the most appropriate for each machining operation. It was attached to the machine tool in the direction and height.

  On the other hand, in the system of the present embodiment, the concept of machining set is introduced. The “machining set” is a jig and a workpiece attached to the jig at a predetermined position and angle. Since the jig can be easily fixed to the machine tool, if this processing set is completed, the jig can be fixed to the machine tool and processing can be started immediately. In this specification, for convenience of explanation, a portion of the jig that is directly fixed to the machine tool is referred to as a “pallet”, and a narrowly defined jig provided between the workpiece and the pallet as needed is simply referred to as “jiring”. Sometimes referred to as “tool”.

  In this embodiment, when the workpiece is for a mold or a core, the workpiece is mounted directly on the pallet. However, for other relatively small workpieces, a jig is fixed on the pallet and this jig is fixed. Fix the workpiece to the tool.

  It is necessary to create the machining set before starting the actual machining operation. In general, the work of mounting a workpiece at the correct position on the pallet is called “setup”. Up until now, setup was generally performed on a machine tool, but in this embodiment, it was separated from the machine tool. It has the feature that this setup work is performed by making a machining set in advance at the place. Note that the work that the machine tool can automatically perform the machining work in one setup is an example of the “unit machining work” recited in the claims.

  FIG. 19 shows an example computer terminal screen showing a list of tasks for creating a machining set. In FIG. 19, only one machining set creation task is displayed in a list. Here, when an operator tries to create a machining set and double-clicks a task listed here, a screen shown in FIG. 20 is displayed. This is information about one work necessary for the processing set to be created. The worker first takes out the work from the storage location designated by K2 Pharmacy. Then, the RFID tag is read in accordance with the instruction of K2 Pharmacy, and K2 Pharmacy determines whether the workpiece is correct from the information.

  Here, if the work is wrong, a warning notifying the operator of that fact is displayed. On the other hand, if the work is correct, viewer software (hereinafter simply referred to as “viewer”) is started. The viewer is a three-dimensional display of the completed state of the machining set to be created on the display of the computer terminal. At the same time, K2 Pharmacy will tell you which pallets and jigs you need to create the processing set to use. RFID tags are also attached to pallets and jigs, and K2 Pharmacy manages them individually. Based on this information, the pallets and jigs to be used are designated on the screen.

  FIG. 21 shows an example of a screen displayed on the viewer. The operator looks at the display on the viewer and performs the machining set creation work while considering the positional relationship between the workpiece and the pallet so that the same thing can be achieved. Since the positional relationship between the workpiece and the pallet can be visually grasped three-dimensionally on the screen, it can be confirmed by changing the orientation from various angles on the screen. For this reason, even an inexperienced worker can work at a constant speed and can reduce work mistakes.

  The viewer closes this screen after checking the viewer and confirming that the same machining set has been created and that the machining set as displayed in the viewer is complete. Then, the screen shown in FIG. 22 appears. This is the setup end screen. Look at the information displayed here, and if there is no mistake, press the “OK” button. On the other hand, if you want to see the machining set again, press the “Viewer” button.

  When the “OK” button is pressed on the screen of FIG. 22, the screen shown in FIG. 23 is displayed. The operator reads the RFID tag attached to the work with the RF reader / writer according to the instruction displayed in the area indicated by reference numeral 24. Then, an instruction to store the processing set in a predetermined storage location is displayed on the display of the terminal as shown in FIG. 24. When the operator goes to the storage location with the processing set. The lamp of the shelf to be stored is lit in a predetermined color. For this reason, the operator can store it on a predetermined shelf without making a mistake. When the worker returns and clicks the “OK” button after the storage on the predetermined shelf is completed, the lamp goes off and the machining set creation task is also completed.

  This is the end of the work up to the stage prior to the actual processing. The machine set is ready for actual machining whenever the machine tool is available. For those for which processing sets have been created, they are handed over to an application different from K2 Pharmacy to manage the actual processing operations as “processing tasks”, and the progress of the operations, etc. is managed there. . For example, a processing worker who has started work in the morning first reads his or her RFID tag on the display screen of an application that manages the processing work, and looks at the list of processing tasks displayed on the terminal screen to perform the work. Click the task to be performed. Then, since the storage location where the processing set necessary for the processing is stored is displayed, the processing set is taken out from the location as instructed and attached to a predetermined machine tool, and the processing operation is executed.

  When the processing operation is completed, management under the K2 Pharmacy of this embodiment is performed again. When the operator removes all the tools from the machine tool (when reading, the RFID tag is read and sent to the machine tool control software 600), information to that effect is sent to K2 Pharmacy. “Tool set return task” is generated. This is a task for returning a tool.

  When a “tool set return task” occurs, this task and information related thereto are displayed in the task list. FIG. 25 is a screen for displaying a task list of “tool set return task” on the computer terminal of K2 Pharmacy. In this example, only one tool set return task is displayed in the area indicated by reference numeral 26.

  When the “return tool set” button at the bottom of the screen of FIG. 25 is clicked, the screen shown in FIG. 26 is displayed. Then, the operator brings the tool set removed from the machine tool, and the tag attached to any one of the tool sets is read by the RF reader / writer of K2 Pharmacy. K2 Pharmacy identifies the tool and displays a screen as shown in FIG. On the left side of this screen, the total machining time indicating the order of the tool set and how long it has been used for machining is shown. In the “collection processing” box on the right side, individual information regarding a specific tool that has read the RFID tag is shown.

  Here, when this tool is returned as usual, it is confirmed that “Return” is checked by default. On the other hand, when discarding the tool, check “Discard”, and when the tool has been lost, check “lost”. When returning, visually inspect the blade edge for breakage, etc. If there is no abnormality, wash it, return it to the original storage location, and click the “Send” button. Further, as shown in the box on the right side of FIG. 27, each tool has a life (unit: time). When the total machining time exceeds this life, a warning is issued to the operator. . If such a warning occurs, it is desirable to discard the tool.

  This process is repeated for all tools. When this return operation is completed for all the tools, as shown in FIG. 28, the “return task” automatically disappears from the return task list display portion.

  As can be understood from the above description, each tool is completely managed individually, and which tool is in which state is always grasped by a computer. Therefore, if something happens to the tool, it is easy to track and examine it.

  Next, replacement of the broken tool during the machining operation will be described. The machine tool used in the system of the present embodiment is provided with a commercially available laser length measuring device, and using this, it is checked at a predetermined timing whether or not the mounted tool is broken. When the tool breaks, the tool dimensions change, so that the tool breakage can be detected based on the length measurement result of the laser length measuring machine.

  When tool breakage is detected, the machine tool identifies the tool and informs K2 Pharmacy connected via the network that the tool breakage has occurred. Then, in K2 Pharmacy, a task of broken tool replacement as shown in the screen of FIG. 29 occurs. The worker removes the broken tool from the machine tool, brings it to the person in charge of K2 Pharmacy, and reads the RFID of the broken tool with the RF reader / writer. Then, the screen shown in FIG. 30 is displayed. Since K2 Pharmacy knows the type of tool that has been broken, the person in charge will issue the same tool. For the broken tool, “Discard” is checked on the screen on the right side of FIG. 30, and when the “Send” button is clicked, the tool is discarded.

  Subsequently, the screen shown in FIG. 31 appears. This is a screen for newly issuing the same tool that has been broken. The person in charge takes out the same tool from the place where the same tool where the breakage occurred is placed, and here, according to the instruction displayed in the area indicated by reference numeral 28, the RFID tag attached is attached to the RF reader Read with a writer. As a result, the delivery work of a new tool is completed, and this tool is given to the worker. The operator can take it to the machine tool, attach it, and continue the machining operation.

  Next, a task for cleaning up the machining set will be described. FIG. 32 is a screen that displays a task for cleaning up the machining set, and is almost the same screen as FIG. When the worker finishes the work on the machine tool, the work set is removed from the machine tool and brought to the K2 Pharmacy representative. Even if the worker brings it, the K2 Pharmacy representative does not have to perform the return task immediately and can leave the processing set in the temporary storage for a while. Then, when the machining set is returned to the final storage location, this machining set return task is executed.

  When the person in charge of K2 Pharmacy clicks the “work return” button on the screen of FIG. 32, the “work return” screen shown in FIG. 33 appears. Here, when the RFID tag of the processing set to be returned is read, K2 Pharmacy recognizes the processing set, and the screen shown in FIG. 34 corresponding to the processing set appears. In accordance with the instruction displayed in the area indicated by reference numeral 30 on this screen, the person in charge of K2 Pharmacy stores the processing set in a predetermined location (here, “shelf 2”). Also in this case, since the designated shelf has a lamp of a predetermined color, the place can be found immediately. When the “OK” button in FIG. 34 is clicked, the lamp goes off, and at the same time, the machining set return task disappears from the task list in FIG.

  With the series of operations described above, processing that can be executed with a single setup for this workpiece and storage for that purpose have been completed. If machining such as finishing is required for this workpiece with another machine tool, the following machining set creation task and tool creation task are generated on K2 Pharmacy. At this time, if setup change is necessary, a message such as “Please remove the jig and store it on the shelf 2” is displayed. At this time, in the next machining set creation task, the viewer is automatically activated to display the completion status of the machining set to be created next. On the other hand, if a machining set is to be installed on another machine tool without changing the setup, the message “No setup change is necessary. Store it on shelf 2 as it is” is also included. Displayed.

  If this workpiece has been processed at this time, the processing on K2 Pharmacy will end, and the process will move to the next mold assembly process.
