Next, the arithmetic processing means 5 is composed of a CPU (Central Processing Unit) or the like, and executes the information processing program 1a installed in the storage means 4. As shown in FIG. 1, the arithmetic processing means 5 of the present embodiment includes a first generation unit 51, a second generation unit 52, a selection detection unit 53, a change processing unit 54, a processing time calculation unit 55, and the like. It functions as a graph generation unit 56 and a display control unit 57. As the arithmetic processing means 5, an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), or the like may be used instead of the CPU. Hereinafter, each component will be described in more detail.

The first generation unit 51 and the second generation unit 52 are configured by an NC program simulator, and generate a simulation image based on the NC program. In the present embodiment, the first generation unit 51 generates a first simulation image which is a simulation image based on the NC program before the change processing described later. In addition, the second generation unit 52 generates a second simulation image, which is a simulation image based on the NC program after the change processing. Further, the second generation unit 52 generates a second simulation image based on each NC program when there are NC programs separately subjected to two or more different modification processes. The generated first simulation image is displayed in the first simulation display area of the display means 3. The second simulation image is displayed in the second simulation display area of the display means 3.

In the present embodiment, the simulation image is a three-dimensional computer graphics moving image, but the present invention is not limited to this configuration, and still images at predetermined time intervals are displayed in chronological order. May be good. Further, the simulation image also includes an image in which each simulation moving image generated from a plurality of NC programs is connected.

The selection detection unit 53 detects the touch position on the display means 3 input by the user via the input means 2. In the present embodiment, the selection detection unit 53 monitors the touch position on the display means 3. Then, as shown in FIG. 2, when the first simulation image displayed in the first simulation display area is touched (selected), the block or part program corresponding to the selected time point is specified. Further, as shown in FIG. 3, the selection detection unit 53 identifies the touched button when various buttons displayed on the display means 3 are touched.

The change processing unit 54 performs change processing on the block or part program corresponding to the time point selected based on the first simulation image. In the embodiment shown in FIG. 3, the change processing unit 54 makes various changes to the block or part program specified by the selection detection unit 53 when the “change” button displayed on the display means 3 is touch-selected. It is designed to execute processing.

The NC program displayed in the NC program display area shown in FIG. 3 has a sequence number (N number) as one block. However, the present invention is not limited to this. For example, an NC program in which a plurality of blocks are included in the sequence number (N number) may be used. Further, the change process may include not only the specified block but also a plurality of blocks before and after the specified block.

For example, the specified block (N2210 in FIG. 3) and a plurality of subsequent blocks (for example, 10 blocks from N2220 to N2310) may be changed. The change process may also include the deletion of the block. In that case, in the present embodiment, if one block is deleted, the N number is reduced by one. As another example, the identified block (N2210 in FIG. 3), a plurality of blocks before the identified block (eg, 5 blocks from N2160 to N2200), and after the identified block. A plurality of blocks (for example, 5 blocks) may be changed.

Further, the change process may be a change process in which an M code (for example, M98) for calling a macro program or a part program is added to the specified block. When the user selects a predetermined image based on the first simulation image while the macro program or part program is being executed, the macro program itself or the part program itself is changed to another macro program or part program entirely. You may perform the change processing. Further, when the part corresponding to the selected image is a macro program or a part program, a change process for changing a block, a conditional expression, an argument, or the like in the macro program or the part program may be performed.

In the change process, for example, CL data, which is the tool position data related to the NC program before the change, is analyzed so that the non-cutting path where the workpiece is not machined is set to the shortest distance, and the coordinate position set to the shortest distance is defined by a block. The process of changing to an NC program. It is not always necessary to analyze the CL data, and the coordinate position described in the NC program before the change may be changed to generate the NC program after the change. In this case, if the first movement path (incremental coordinate information or absolute coordinate information) of the predetermined tool is programmed in advance, the table of the second movement path of the tool corresponding to the program is stored or the machine. An artificial intelligence department having an artificial intelligence function capable of learning is required.

Further, the NC program used in the past of the machine tool AAA may be analyzed and the selected block may be optimized. For example, when a block for processing a workpiece into a curved surface A is selected and the optimization processing button is pressed, an NC program for processing a curved surface B having a curvature larger than the curved surface A and a curved surface B having a curvature smaller than the curved surface A are processed. An NC program for the curved surface C is generated from the data with the NC program. The generated NC program is compared with the selected block and the CAD data of the curved surface A, and if the generated NC program has a large degree of similarity with the CAD data of the curved surface A, a newly selected block is generated. Change to the NC program and optimize the whole NC program.

As an example of another change process, there is a case where a code for roughing a specific work surface is described in the NC program before the change. In this case, after machining a specific surface so that the tool locus moves on a straight line at a constant pitch, the code is changed so that the tool locus is shifted by half a pitch from the tool locus of the previous machining. The change process may be performed and the changed NC program may be generated. In this change process, it is possible to prevent the tool from being damaged due to a sudden change in the removal allowance, which is likely to occur in rough machining, and to perform an optimization process that can extend the tool life.

As an example of another change process, there may be a program in the NC program before the change that cuts the work at a right angle when viewed along the Z axis. In this case, a change process for inserting a program for adding a curved surface (corner) to a portion where the movement path of the tool is cut at a right angle may be performed to generate a changed NC program. In this case, it is possible to prevent the tool from biting into the part to be cut at a right angle and to prevent the tool from being damaged due to a sudden change in the tool load.

In the present embodiment, the change processing includes shortening of machining time, improvement of machining accuracy, saving of electric power and coolant, efficient removal of chips, efficiency improvement by visualization of process management, prevention of tool damage, and tool replacement. It is a process that brings benefits to machining, such as reducing the frequency.

The processing time calculation unit 55 calculates the processing time before the change processing by the change processing unit 54 and the processing time after the change processing is performed on the block or part program selected based on the first simulation image. To do. Here, the machining time is the time from the start of machining to the time after the code before the change is executed, the time from the start of machining to the time after the code after the change is executed, and the time from the start of program execution to the execution of the code before the change. The time from the start of program execution to the time after the changed code is executed. Further, the machining time may be the execution time before the change of the block to be changed or the time when only the NC code after the change processing is executed. The machining time calculation unit 55 may calculate the difference between the machining time before the change process and the machining time after the change process.

The graph generation unit 56 is a graph showing the execution time of the program and the machining time due to the execution of the program, and generates a graph showing the correspondence time corresponding to the changed program portion in the graph. In the present embodiment, as will be described later, when there is a second simulation image based on an NC program in which two or more different modification processes are separately performed, as shown in FIG. 5, the machining time zone changed by each modification process. It is designed to generate a graph showing.

The display control unit 57 controls the display content of the display means 3. In the present embodiment, the display control unit 57 has FIGS. 2 to 4 based on the simulation image generated by the first generation unit 51 and the second generation unit 52 and the GUI data read from the GUI data storage unit 43. The display means 3 displays the first simulation display area and the second simulation display area as shown in the above.

Further, the display control unit 57 causes the display means 3 to display the NC program display area as shown in FIG. 3 based on the NC program read from the NC program storage unit 42 and the GUI data. Then, the display control unit 57 displays the block or part program selected by the selection detection unit 53 so that it can be distinguished from other parts of the NC program. As the identification display, in addition to the arrow as shown in FIG. 3, bold characters or highlight display may be displayed, or the color may be changed to a conspicuous color.

Further, the display control unit 57 displays a machining time display area as shown in FIG. 4 and a graph display area as shown in FIG. 5 based on the machining time calculated by the machining time calculation unit 55 and GUI data. It may be displayed on the display means 3.

Next, the operation of the information processing device 1 and the information processing program 1a of the present embodiment will be described.

Hereinafter, with respect to the process of optimizing the NC program using the information processing device 1 and the information processing program 1a of the present embodiment, FIG. 6 is used in accordance with the process of operating the graphical user interface displayed on the display means 3. I will explain.

When optimizing the NC program using the information processing device 1 and the information processing program 1a of the present embodiment, first, the first generation unit 51 is based on the machine tool information A of the machine tool A (5-axis machine tool). Generates a first simulation image based on the NC program (step S1). As shown in FIG. 2, the display control unit 57 displays the first simulation image in the first simulation display area (step S2).

Here, the machine tool information A is information including information common to the machine tool A (5-axis machine tool) and information unique to each product of the machine tool A (5-axis machine tool). Information common to machine tool A includes, for example, the machine origin in a 5-axis machine, the machine stroke length in a 5-axis machine, the spindle diameter, and the NC program part program that can be used in a 5-axis machine. Tools that can be used in shaft processing machines. Machine tool information specific to each product includes product number AAA of machine tool A (5-axis machine), machine origin of product number AAA, machine stroke length of product number AAA, type of chip conveyor (chip conveyor AAA), and There are NC program part programs that can be used in the chip conveyor AAA, types of numerical control devices (manufactured by C company, D company, etc.) and the like.

Next, when the user touches the first simulation image at the timing desired to be optimized while viewing the first simulation image, the selection detection unit 53 detects the selection based on the first simulation image (step S3). Then, the display control unit 57 displays the block or part program corresponding to the selected time point so that it can be distinguished from other parts of the NC program (step S4). As a result, the user can intuitively select the part to be optimized while viewing the simulation image, and the operability is improved.

Subsequently, as shown in FIG. 3, when the user touches the "change" button on the display means 3, the change processing unit 54 shifts to the block or part program corresponding to the time selected based on the first simulation image. Perform the change process (step S5). When the user touches the "restart" button on the display means 3, the reproduction of the first simulation image is restarted, and the portion to be changed can be reselected.

Next, the second generation unit 52 generates a second simulation image based on the NC program after the change processing (step S6), and the processing time calculation unit 55 sets the processing time before the change processing and the change processing. The processing time after the above is calculated (step S7). As a result, as shown in FIG. 4, the display control unit 57 displays the second simulation image in the second simulation display area in addition to the first simulation image (step S8), and attaches the second simulation image to each simulation display area. The processing time before and after the change processing is applied to each processing time display area is displayed (step S9).

In the present embodiment, the machining time is shortened by shortening the moving path of the tool. Therefore, a change process for changing the NC code such as the coordinate position of the selected block or the tool of the part program and the movement command to the coordinate position is performed. In FIG. 4, the first simulation image is a moving image in which the tool moves upward once in the machining area, then moves to the left side of the drawing, and then moves toward the machining position. On the other hand, in the second simulation image, the tool moves to the left side without retracting upward, and then moves toward the machining position.

By executing steps S1 to S9, the user can intuitively grasp the machining time shortened by performing the change process and easily determine whether or not to adopt the change process. Then, as shown in FIG. 4, when the user touches any of the "selection" buttons on the display means 3, the selection detection unit 53 detects the selection by the user (step S10), and the NC of the selected one is detected. The program is stored in the NC program storage unit 42 (step S11).

In the present embodiment, the case of simulating a single change process has been described, but the present invention is not limited to this configuration, and an NC program in which two or more different change processes are separately performed is simultaneously simulated. You may do it. For example, as shown in FIG. 5, a second simulation image based on an NC program in which a plurality of second simulation display areas are arranged and a change process for optimizing the machining time is performed, and a change process for optimizing the tool change frequency is performed. Each of the second simulation images based on the applied NC program may be displayed.

Further, the graph generation unit 56 may generate a graph showing the processing time zone by each change processing and display it in the graph display area as shown in FIG. As a result, the user can intuitively grasp the time zone optimized by each change process and easily determine which change process is to be adopted. Details will be described below.

FIG. 5 shows the second simulation image A of the NC program that has been changed to shorten the moving path of the tool that can shorten the machining time, and the change process that lowers the rotation speed so that the tool change frequency is reduced. A second simulation image B of the NC program is generated and displayed in the second simulation image display area on the display means 3.

Further, in the display of the display means 3 shown in FIG. 5, two graphs are displayed in the lower graph display area. One graph (first graph) is a graph showing the execution time when the NC program that has not been changed is executed. In FIG. 5, the NC program that has not been changed shows an example of a band graph in which the execution of the program is completed in about 20 minutes. The execution time of the program of the present embodiment is also referred to as a machining time because it is also a time when the work is machined and the machining of the work is completed.

On the other hand, the other graph (second graph) is an example of a band graph showing the execution time of the NC program in which the change process A for shortening the tool movement path and the change process B for lowering the rotation speed of the tool spindle are performed. is there. In the second graph, the time of the portion corresponding to the change process A is shown as time A1 and time A2, and the time of the portion corresponding to the change process B is shown as time B1 and time B2. Similarly, in the first graph, the time of the part corresponding to the change process A before the change process is shown as time A1 and time A2, and the time of the part corresponding to the change process B before the change process is time B1 and time B2. It is shown as.

In FIG. 5, since the first graph and the second graph are displayed side by side in the graph display area, it is intuitively understood that the processing time by executing the NC program is shorter in the second graph. To. Further, the change process A contributes to shortening the machining time, but the change process B does not contribute to shortening the machining time, and the machining time itself is long. Therefore, based on the information displayed on the display means 3, the user selects an NC program in which only the change processing A is performed for the purpose of shortening the processing time, and selects to process the work. You can also. In this case, press or click the A selection button shown in FIG.

In addition, although the machining time will be slightly extended, the frequency of tool changes will be reduced, so for the purpose of reducing the cost of purchasing tools, select an NC program that has performed only change processing B, and machine the workpiece. You can also select. In this case, press or click the B selection button shown in FIG.

In FIG. 5, the second graph shows the machining time when the NC program in which the change process A and the change process B are performed is executed. The machining time shown in the second graph is shorter than the machining time when the NC program in which the change process B is performed but no change process is executed is executed. Therefore, it is also possible to select to process the work by using the NC program in which the two change processes (change process A and change process B) are performed. In this case, press or click the button for selecting both A and B shown in FIG.

According to the above-described first embodiment, the following effects are obtained.
First,
1. 1. The user can intuitively select the part to be changed while looking at the simulation image, and the operability can be improved.
Further, it has the following effects depending on the mode of displaying on the display means 3.
2. It is easy to intuitively grasp the processing time shortened by performing the change processing and determine whether or not to adopt the change processing.
3. 3. When simulating two or more change processes that are different from each other, it is easy to intuitively grasp the time zone optimized by each change process and determine which change process to adopt.

<Embodiment 2>
FIG. 3 of the first embodiment is a mode in which a second simulation image is generated by clicking the change button. On the other hand, in the second embodiment, as shown in FIG. 7, another window opens after clicking the change button, and an edit screen having an input field for inputting modal commands and coordinates is displayed.

For example, in the first simulation image shown in FIG. 3, a time point including the process to be changed is selected, the simulation is stopped at that point, and the corresponding NC program is confirmed. The NC program can be confirmed not only by a part of the NC program displayed in FIG. 3, but also by scrolling up and down to confirm the part of interest to the operator. If you want to check the NC program and change it, press the change button shown in FIG. 3, and the edit screen shown in FIG. 7A is displayed.

On the edit screen shown in FIG. 7A, if there is a modal command at the time of selection, the modal command is displayed, and in the present embodiment, the modal command code of "G00" is displayed. On the edit screen of this embodiment, since the modal command of "G00" can be edited, it can be changed to "G01" or the like.

Further, on the editing screen shown in FIG. 7A, a corresponding block corresponding to the selected image selected in the first simulation image is displayed as a selection point. In the present embodiment, the X coordinate, the Y coordinate, and the Z coordinate are displayed, and the numbers of the X coordinate, the Y coordinate, and the Z coordinate can be changed, respectively. In addition, the corresponding simulation image corresponding to the corresponding block is displayed. This makes it possible to change the numerical values of the coordinates while checking the simulation image. In this embodiment, the blocks are only related to coordinates, but are not limited thereto. The editing screen may be such that the block itself is displayed and can be freely edited. The simulation image corresponding to the block here may be not only a simulation movie of only the selected block but also a simulation movie including a plurality of blocks before and after the selected block. In the simulation video corresponding to a plurality of blocks, when the video of the selected block is displayed, the color of the background image may be changed so that the simulation video can be distinguished from other videos.

Edit as necessary on the edit screen. After confirming the contents of the edit screen, when the change button is pressed again, the change process is performed and the second simulation image based on the changed NC program is generated. The generated second simulation image is displayed in the second simulation display area. By doing so, the change of the program according to the needs of the worker can be intuitively understood by the worker, and the program can be changed accurately according to the needs of the worker. Although the edit screen is a separate window, it may be displayed in a separate tab.

Also in FIG. 7B, when the change button is clicked, the edit screen is displayed in a separate window. On the edit screen, the corresponding block corresponding to the selected screen is displayed as a selection point. Only the serial number is editable in that block. In the present embodiment, since the serial number and the block correspond to each other, although the corresponding block is selected, it may be different from what the user thinks when checking the simulation image displayed there. Therefore, the block itself (in this embodiment, the serial number is changed) can be edited. The serial number may be entered directly or may be selected by scrolling. A simulation image corresponding to the selected serial number is displayed in the simulation display area.

<Embodiment 3>
In this embodiment, a mode in which a G code is generated from STL format data and a workpiece is produced by an additional machining machine tool will be described. First, the CAD data is converted into STL format data, and the information on the material used for the workpiece and the information on the machine tool of the additional processing machine are combined to create the G code before the change. After creating the G code, a first simulation image showing the process of creating the workpiece based on the G code is generated. The generated first simulation image is displayed in the first simulation display area.

While watching the moving image displayed in the first simulation display area, the operator stops the moving image at the place where he / she wants to change. At that time, when the change button displayed on the display means 3 is clicked, the corresponding G code portion is optimized and the changed G code is generated. A second simulation image based on the modified G code is generated and displayed in the second simulation display area.

<Others>
The information processing device 1 is not limited to the above-described embodiment, and can be changed as appropriate. For example, in the first embodiment, the first generation unit 51 and the second generation unit 52 generate a simulation image based on the NC program, but the present invention is not limited to this configuration, and the structural data of the machine tool , A simulation image may be generated based on the information of the machine tool used to process the work piece.

In this case, the first generation unit 51 generates a first simulation image based on the structural data of the workpiece and the information of the machine tool, and displays it in the first simulation display area. Further, the change processing unit 54 sets the corresponding portion of the structural data of the selected workpiece or the machine tool with respect to the structural data of the workpiece or the information of the machine tool corresponding to the time selected based on the first simulation image. Change the relevant part of the information in. Then, the second generation unit 52 generates a second simulation image based on the structural data of the workpiece changed by the change processing unit 54 and the information of the machine tool, and displays it in the second simulation display area.
