Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to an inserting method for inserting an NC program to be processed by a numerical control (NC) device into digitizing data created by a copying device, and in particular, a single digitizing process. Thus, the present invention relates to an insertion method that allows a predetermined NC program to be easily inserted into a plurality of different NC devices.

(Technical background of the invention and its problems) The digitizing data collected by the copying apparatus is
It only shows the position data of the workpiece, and machining cannot be performed by the NC device only with this digitizing data. Therefore, when machining is performed by the NC device, a predetermined “G code (preparation function)”, “M code (auxiliary function)”, “T code (tool function)” is set at a predetermined position of the digitizing data. , Machining programs must be created by inserting the corresponding NC programs, including various functions such as "F code (feed function)" or "S code (spindle function)", and machining must be instructed.

Therefore, conventionally, different NC program identification information (hereinafter referred to as NC program name) is attached to each NC program to be inserted in the digitizing data in advance and registered, and at the time of digitizing start, end or pick feed start. Register the NC program name to be inserted in the NC program insertion step (hereinafter referred to as insertion timing) at the time of termination, etc. Then, in this state, digitizing is started, and for each of the inserted NC program names, the corresponding NC program from the registered NC programs is inserted into the digitizing data each time, and the predetermined "processing" is performed. Program ”(a predetermined NC program inserted in the digitizing data, the same applies below)
I am trying to create.

However, when machining is performed by the NC device using the machining program created by such a conventional insertion method, if two different NC devices are attempted to be machined using the same machining program, the same NC program may result. The machining program cannot be used and the NC program to be inserted is changed for each NC device and digitized to create a machining program (hereinafter referred to as "two times digitizing"), or the first digitizing. After the completion, it was necessary to change the inserted NC program to correspond to the next NC device to create an additional program, which put a great burden on the operator. Also, after digitizing,
Even when the NC device to be machined is changed due to circumstances, it is necessary to perform digitizing twice or change the inserted NC program in the same manner, which causes a great burden on the operator. It was

(Object of the Invention) The present invention has been made under the circumstances as described above, and an object of the present invention is to perform machining by NC using a machining program in which a predetermined NC program is inserted into digitizing data. Even when using different NC units, it is possible to supply a machining program suitable for each NC unit with a simple operation by just digitizing once, and the NC unit that actually processes after completion of digitizing. It is to provide a method for inserting an NC program into digitizing data that can be flexibly handled by a simple operation even if the value is changed.

(Summary of the Invention) The present invention relates to a method for inserting an NC program into digitizing data capable of flexibly accommodating a plurality of different NC devices. The NC program driving each NC device has the same program for the same machining process. In addition to giving a name, each of the above NCs
The NC is divided according to the device and given a file name.
The programs are stored in association with each other, and when the digitizing data is created by the copying apparatus, the program name is inserted at each timing of inserting the NC program, and the file name is designated after the digitizing is completed. By doing so, it is possible to insert an NC program corresponding to each NC device to be actually machined by one-time digitizing into a predetermined position of the digitizing data.

(Embodiment of the Invention) FIG. 1 is a block configuration diagram and a flow thereof showing an outline of an apparatus for realizing an NC program insertion method into digitizing data of the present invention. In the figure, 1 is the third
As shown in the figure, it is a correspondence table that correlates the NC program insertion timing to the predetermined position of the digitizing data and the NC program name to be inserted.
When SS is input, the corresponding NC program name is output. Reference numeral 2 is a memory for storing digitizing data. As shown in FIG. 5, the NC program name output from the above correspondence table 1 is followed by a program call command such as "CALL" or "GOSUB". The digitizing data is inserted into a predetermined position and stored. 3, the NC program groups corresponding to the NC program names to be inserted differently for each NC device, as shown in FIG. 4, are given individual file names for each of the above NC devices and stored together in one file. The correspondence table 1 and the file group 2 are created separately in advance. Reference numeral 4 is a file designation memory for designating a file name corresponding to each NC device from the file group 3, and reference numeral 5 is the digitized data stored in the memory 2 and showing the NC program insertion position. A synthesizer for selecting a file name designated by the file designation memory 4 from the file group 3 and creating a machining program in which a predetermined NC program is inserted at a predetermined position of the digitizing data as shown in FIG. Is.

NC to digitizing data using such a configuration
The method of inserting the program will be described in detail below with reference to the flowchart of FIG.

For example, when digitizing work shape data as shown in FIG. 7, the file group 3 and the file designation memory 4 have predetermined file names and corresponding NCs in advance.
It is assumed that the program name and NC program are stored. Therefore, digitizing is performed to create the position data of the work (step S1), but this digitizing does not end (step S2), and the procedure returns to step S1 until the timing to insert the NC program is reached. (Step S3). Here, since the digitizing start point Ds is the NC program insertion timing, the insertion timing signal is shown in the correspondence table 1 above.
When SS is entered, the corresponding NC program name (1000)
Is output (step S4). Therefore, as shown in FIG. 5, the digitizing data in the memory 2 is called with the call command "CALL" and the NC program name (100
0) is inserted and stored (step S5). And
By returning to the step S1 and repeating the digitizing, the position data (X100 Y100 Z100) of the start point is output, and thereafter, by repeating the above operation, a predetermined insertion timing, for example, pick feed start point Ps, pick At the feed end point Pe, the digitizing end point De, etc., the digitizing data in which the NC program name to be inserted is inserted is stored in the memory 2.

When the creation of all digitizing data is completed in this way (step S2), a file name (for example, "ARA.SUB") corresponding to the file designation memory 4 is designated according to the NC device to be actually processed ( Then, the synthesizer 5 reads the digitizing data (see FIG. 5) in which the NC program name stored in the memory 2 is inserted (steps S7 to S8), for example, " If there is a program name to be inserted, such as CALL1000 ”(step S10), the NC program name (“ 1000 ”) of the specified file (“ ARA.SUB ”)
NC program (“G00 Z500 / G01 S1000 T010
1 MO3 F200 ”) from the file group 2 (step S 11) and if there is no NC program (step S 1)
2) The error processing is performed (step S13), and if there is, the NC program is inserted into the digitized data as shown in FIG. 6 (step S14). Then, the above step S7
Then, the digitizing operation as described above is repeated.
If it is not the NC program insertion timing in step S10, the process returns to step S7 and the digitizing data is read as it is.

Then, after repeating the above steps S7 to S14, the digitizing data is read in the same manner as described above, and each insertion NC
The creation of the machining program in which the NC program corresponding to each program name is inserted is completed (step S9).

(Effect of the Invention) As described above, according to the NC program insertion method for digitizing data of the present invention, a machining program in which a predetermined NC program is inserted in the digitizing data is used.
When machining with an NC unit, you can create a NC program that assigns a file name to each NC unit to be machined and associates the NC program name with each other, even if you use different NC units. With just one digitizing,
A machining program suitable for each NC unit can be supplied by a simple operation, and the actual machining is performed after digitizing is completed.
Even if the NC device is changed, you can flexibly respond with simple operation.
Not only can the burden on the operator be reduced, but the versatility can be expanded.
