FIG. 2 is a flow chart showing the NC data editing method of the present invention. Next, the NC data editing method of the present invention will be described based on the flow chart of FIG. In this embodiment, as shown in FIG. 10, different kinds of works W ₁ , W
NC data for individually machining each of ₂ , W ₃ and W ₄ has already been created, and different types of workpieces W ₁ , W ₂ and W that are positioned and mounted at a predetermined position on the table B of the vertical machining center. A case of processing ₃ and W ₄ will be described. First, the NC data for processing each of the different types of workpieces W ₁ , W ₂ , W ₃ , and W ₄ is created using the keyboard 14 or the NC is performed prior to the automatic editing of the data.
The NC data is read and input from the memory card via the data input device 15 and registered in the memory A4 (steps S1 and S2). FIG. 3 shows NC data of each created work. F1 shows NC data of the work W ₁ , F2 shows NC data of the work W ₂ , and F3 shows N data of the work W ₃ .
C data is shown, and F4 is NC data of the work W ₄ .

The operator displays the NC data on the CRT 13, judges whether there is a portion to be changed (step S3), and if there is a changed portion, edits the changed portion (step S4). For example, when arranging the workpieces at the positions shown in FIG. 10, the workpiece coordinate systems are assigned to the workpieces W ₁ , W ₂ , W ₃ , and W ₄ and set. In this embodiment, the work W ₁ is the work coordinate system selected by the work coordinate system setting selection command G 54, and the work W ₂ is the work coordinate system selected by the work coordinate system setting selection command G 55.
The workpiece coordinate system to the work W ₃ is selected in the work coordinate system set selection command G56, been described in example of dividing attached set the work coordinate system selected by the workpiece coordinate system set selection command G57 is the work W ₄ ing. If the work coordinate system setting selection command in the created NC data does not match the assigned work coordinate system setting selection command in advance, it is necessary to change it, so this work coordinate system setting selection command must be changed. Manual editing for changing to the setting selection commands G54 to G57 is performed. It is also confirmed whether the T code in the NC data of each work is commonly used. For example,
T number "T0" used in O number "O1 to O4"
1 "is an end mill with a tool diameter of 10 mm, and T number" T0
Check whether "2" commonly uses a drill with a tool diameter of 5 mm, and if not, perform manual editing. Next, when the automatic editing start operation is performed, the CPU 1 causes the memory A4
NC data in the first block, that is, O
A process of sequentially reading from the number "O1", searching for only the T code, and taking out in order is performed. That is, the O number "O
If the NC data is "1", T code "T01", "T"
02 ”... is sequentially read, and the O number“ O ”of the file B6 is read.
1 ”is sequentially stored in the register F1 (step S
5). Similarly, N of O number "O2", "O3", "O4"
The T code is also extracted from the C data and stored. FIG. 4 is an example of the file B6 stored in the process of step S5.

When the file B6 is created, the CPU 1 compares the order of the T-codes corresponding to the respective O-numbers of the file B6, and when there are the same T-codes, performs a process of recreating the order so as to make them common, The recreated new tool order is registered in the file C8 (step S6). That is,
First, as shown in FIG. 5, the O number “O1” (that is, F number)
The tool order of 1) is compared with the O number “O2” (that is, F2), and the tools of the same T code which are closer in the machining order process the work W ₁ and the work W ₂ continuously, that is, the tool. A new tool sequence F0 is created by grouping the machining operations in common so as to reduce the exchange operation as much as possible.
In other words, after the NC data which is the machining process program of “T1” and “T2” of the O number “O1”, “T” of the O number “O2”
Insert the NC data which is the machining process program of "2",
Next, the tool numbers “T11” of the O number “O1”, “T2” and “T10” of the O number “O2” are collected and stored in this order.
Then, the new tool order F0 is compared with the tool order with the O number "O3" (that is, F3), and a new tool order F0 ₁
Is created (see FIG. 6). Further new tool order F0 ₁ and O
The tool order of the number “O4” (that is, F4) is compared to create a new tool order F0 ₂ (see FIG. 7). In addition,
As shown in FIG. 8, the final tool order is the file number (TNo.) In the file C8, the program number to which it belongs (ON).
o.) is registered in the processing order.

When the processing of step S6 is completed, the results can be displayed in a list on the screen of the CRT 13, and if there is a change, the operator can manually edit it (step S7). Next, the CPU 1 performs a process of extracting the NC data in the memory A4 for each tool (step S8). That is, the tool change command (T **
The block including the work coordinate system setting selection command (G54 to G59) that first appears after the block of M06;) is set as the extraction start block and the next tool change command (T **).
M06;) or program end command (M3
0;) before the reference point return command (G28 ...) Is not taken out as an end block, and the block (NC data) between them is taken out as a machining process program of this tool number command data (T **). . If there is a tool change operation, the tool change command data is inserted between the NC data. The NC data thus extracted is registered in the file D10 for each program number and each tool number. That is, from the unification tool number command data of the file C8 and the NC data for each tool number command data of the file D10, the NC data corresponding to this tool number command data is edited and unified in the order of the tool number command data. Processing is performed (step S9). After the editing of the unified NC data is completed, the program number (for example, O1000;) assigned to the unified NC data and the program of the O number "O1" are added to the front part of the unified NC data. Command block for moving to the ATC position at the beginning of the (eg, G91 G28 X0 Y0 Z
0; ...; G92 X0 Y0 Z0;) is added. A reference point return command (for example, G91 G28 X0 Y0) is added to the rear of the unified NC data.
Z0;), program end command (for example, M30;)
To add. This ends the NC data editing process. NC with program number “O1000” in memory A4
Register the data. In addition, in this embodiment, the data of different kinds of workpieces are collected and unified, but NC data for front and back processing of the same workpiece may be collected and unified. In addition, the work coordinate system setting selection command for the work is set to G54 to G5.
However, the present invention is not limited to this.
Further, the same processing method can be used to edit the NC data of the vertical machining center into the NC data for the horizontal machining center. That is, the works W ₁ , W ₂ , W ₃ and W ₄ are attached to the respective surfaces of the scales erected on the pallet, and the works W ₁ , W ₂ , W ₃ and W ₄ are attached to the NCs for the vertical machining center. The data may be edited into NC data for a horizontal machining center. However, in this case, the workpiece _{W 1, W 2, W 3} , W 4 is any tombstone of B-axis command that indicate is attached to surface data (B0, B90, B180, B270 ) is a work coordinate system setting Similar to the selection command (G54 to G57), it is necessary to set the allocation.

[0012]

As described above, when a plurality of NC data are collectively edited, a simple operation can be performed even if the operator is not familiar with the operation for creating NC data and the editing operation. With, multiple NC data can be automatically edited into one.
That is, the NC data created for the vertical machining center can be edited for the horizontal machining center. Furthermore, it is possible to edit so that different kinds of workpieces or the same workpiece can be processed on the front and back sides. This has the remarkable effect of improving the productivity of the machine and the flexibility of processing.

FIG. 2 is a flow chart showing the NC data editing method of the present invention. Next, the NC data editing method of the present invention will be described based on the flow chart of FIG. In this embodiment, as shown in FIG. 10, different kinds of works W ₁ , W
NC data for individually machining each of ₂ , W ₃ and W ₄ has already been created, and different types of workpieces W ₁ , W ₂ and W that are positioned and mounted at a predetermined position on the table B of the vertical machining center. A case of processing ₃ and W ₄ will be described. First, the NC data for processing each of the different types of workpieces W ₁ , W ₂ , W ₃ , and W ₄ is created using the keyboard 14 or the NC is performed prior to the automatic editing of the data.
The NC data is read and input from the memory card via the data input device 15 and registered in the memory A4 (steps S1 and S2). FIG. 3 shows NC data of each created work. F1 shows NC data of the work W ₁ , F2 shows NC data of the work W ₂ , and F3 shows N data of the work W ₃ .
C data is shown, and F4 is NC data of the work W ₄ .

The operator displays the NC data on the CRT 13, judges whether there is a portion to be changed (step S3), and if there is a changed portion, edits the changed portion (step S4). For example, when arranging the workpieces at the positions shown in FIG. 10, the workpiece coordinate systems are assigned to the workpieces W ₁ , W ₂ , W ₃ , and W ₄ and set. In this embodiment, the work W ₁ is the work coordinate system selected by the work coordinate system setting selection command G 54, and the work W ₂ is the work coordinate system selected by the work coordinate system setting selection command G 55.

When the processing of step S6 is completed, the results can be displayed in a list on the screen of the CRT 13, and if there is a change, the operator can manually edit it (step S7). Next, the CPU 1 performs a process of extracting the NC data in the memory A4 for each tool (step S8). That is, the tool change command (T **
The block including the work coordinate system setting selection command (G54 to G59) that first appears after the block of M06;) is set as the extraction start block and the next tool change command (T **).
M06;) or program end command (M3
0;) before the reference point return command (G28 ...) Is not taken out as an end block, and the block (NC data) between them is taken out as a machining process program of this tool number command data (T **). . If there is a tool change operation, the tool change command data is inserted between the NC data. The NC data thus extracted is registered in the file D10 for each program number and each tool number. That is, from the unification tool number command data of the file C8 and the NC data for each tool number command data of the file D10, the NC data corresponding to this tool number command data is edited and unified in the order of the tool number command data. Processing is performed (step S9). After the editing of the unified NC data is completed, the program number (for example, O1000;) assigned to the unified NC data and the program of the O number "O1" are added to the front part of the unified NC data. Command block for moving to the ATC position at the beginning of the (eg, G91 G28 X0 Y0 Z
0; ...; G92 X0 Y0 Z0;) is added. A reference point return command (for example, G91 G28 X0 Y0) is added to the rear of the unified NC data.
Z0;), program end command (for example, M30;)
To add. This ends the NC data editing process. NC with program number “O1000” in memory A4
Register the data. In addition, in this embodiment, the data of different kinds of workpieces are collected and unified, but NC data for front and back processing of the same workpiece may be collected and unified. In addition, the work coordinate system setting selection command for the work is set to G54 to G5.
However, the present invention is not limited to this.
Further, the same processing method can be used to edit the NC data of the vertical machining center into the NC data for the horizontal machining center. That is, the works W ₁ , W ₂ , W ₃ and W ₄ are attached to the respective surfaces of the scales erected on the pallet, and the works W ₁ , W ₂ , W ₃ and W ₄ are attached to the NCs for the vertical machining center. The data may be edited into NC data for a horizontal machining center. However, in this case, the workpiece _{W 1, W 2, W 3} , W 4 is any tombstone of B-axis command that indicate is attached to surface data (B0, B90, B180, B270 ) is a work coordinate system setting Similar to the selection command (G54 to G57), it is necessary to set the allocation.

[0012]

As described above, when a plurality of NC data are collectively edited, a simple operation can be performed even if the operator is not familiar with the operation for creating NC data and the editing operation. With, multiple NC data can be automatically edited into one.
That is, the NC data created for the vertical machining center can be edited for the horizontal machining center. Furthermore, it is possible to edit so that different kinds of workpieces or the same workpiece can be processed on the front and back sides. This has the remarkable effect of improving the productivity of the machine and the flexibility of processing.
