Further, below the spindle head 13, an X, Y table 10 capable of moving the workpiece W at an arbitrary position in the horizontal direction is attached.

A central processing unit (hereinafter a CPU) in the computer 19
As shown in FIG. 1, a ROM 9 in which various control programs and the like are stored, a RAM 1 as storage means for storing processing information and the like set from the keyboard 6 are connected to the The keyboard 6 and the CRT 7 are connected.

In the RAM 1, an area 3 as a third storage area for storing a series of machining programs input from the keyboard 6 according to the display of the CRT 7, a positioning operation of the tool 21 corresponding to complicated machining required by the user, An area 4 as a second storage area for storing an operation program in which machining operations such as rotation of the spindle 14 are sequentially input, and a first memory in which each machining operation and input items necessary for the machining operation are stored.
An area 8 is provided as a storage area. The RAM 1 is configured to be writable by programs of program numbers 0001 to 9999.
Numbers 0001 to 9799 are stored in machining program storage area 3 again
The numbers 9800 to 9999 are assigned to the operation program storage area 4.

The present embodiment is configured as described above, and its operation will be described by taking as an example a procedure of creating a machining program for performing jump feed machining on a workpiece 2 having a U-shaped cross section as shown in FIG. A description will be given below according to the flowchart of FIG.

First, as shown in FIG. 4, the keyboard 6 is operated to select the processing program edit mode screen, and the seven menus are displayed on the CRT 7, and the processing is performed at the menu input location where the cursor 7a is blinking. When number 1 for inputting a program is input from the keyboard 6, the CPU 5 executes step S1 and displays a program number input screen shown in FIG. 5 on the CRT 7.

Here, if the operator wants to create a machining program, he or she may input a desired program number of program numbers 0001 to 9799 to the input location where the cursor 7a is blinking. On the other hand, when an operation program is to be created by sequentially inputting machining operations, desired program numbers 9800 to 9999 may be input in the same manner as described above.
Then, when a predetermined program number is input by the operator, the CPU 5 executes step S2 to determine the program number.

The program number input in step S2 is
If it is determined that the number is 9800 to 9999, step S3 is executed to determine whether or not the editing of the operation program has been completed based on the input of the operator. Then, when it is determined in step S3 that the editing is not completed, step S4 is executed and a screen for inputting the type of operation is displayed on the CRT 7 based on the contents of the storage area 8 of the RAM 1 (see FIG. 6). This FIG. 6 corresponds to the screen for defining the machining operation.

The six menus displayed on this screen are stored in the area 8 of the RAM 1 as shown in FIG. 7, classified into concrete actions corresponding to the respective actions.

Further, as will be described later, after the operator defines the machining operation according to the display on the CRT 7, the determination in the step S3 is performed.

Here, for example, in order to process the workpiece 2 (see FIG. 2), as shown in FIG. 8, it is possible to perform the operations 1 to 8 in order in the fastest and efficient manner.

Accordingly, when the menu number is input as "1" at the blinking position of the cursor 7a on the screen shown in FIG. 6 based on the above operation, the CPU 5 displays the screen shown in FIG. 9 on the CRT 7. Further, when the menu number “1” is input to set the positioning XY which is the operation corresponding to the operation of “1” (see FIG. 8), the screen shown in FIG. -Define XY motion.

Further, by inputting each menu corresponding to the operations 2 to 8 (see FIG. 8) in accordance with the display on the CRT 7 in the same manner as described above, a series of machining operations is defined as shown in FIG. After that, a predetermined key input indicating the end of the program is input from the keyboard 6 to display the program end (see FIG. 12), and the series of operations is stored in the program number 9800 of the operation program storage area 4. In step S5, the display of CRT7 is returned to the initial screen shown in FIG.

Here, when it is desired to define another machining operation again, the program numbers 9800 to 9999 different from the above program numbers may be input and input as described above.

After some operation programs are defined as described above, enter menu number 1 on the screen shown in FIG. 4 and program number 00 on the screen shown in FIG.
When numbers 01 to 9799 are input, step S10 is executed, and as shown in FIG. 14 to FIG. 17 of JP-A-61-86153, each data is sequentially input according to the display screen of CRT7. As a result, predetermined screens are displayed one after another. Then, when the work material is selected from the menu and entered on the screen shown in FIG. 17 of the publication, the screen shown in FIG.
Display on T7.

Next, in step S11, it is determined whether or not the editing of the machining program is completed, then step S12 is executed, and the type of process input by the operator is the operation call menu 14 (see FIG. 13). To determine.

If it is determined that the type of the input process is not the operation call, step S13 is executed, and the necessary input items are sequentially displayed on the CRT 7 as described in the above-mentioned publication, and each data is provided to the operator. Input. Then, when a machining program for one process is input, the determination in step S11 is performed.

In step S12, when it is determined that the type of the input process is an operation call, as shown in FIG.
Of the operation programs stored in the predetermined program number of the operation program storage area 4, a desired program number to be read during the machining program and the number of the tool 21 to be used stored in a predetermined area (not shown) of the RAM 1 Is input by the operator.

Next, when step S14 is executed and it is determined that the program number and the tool number are input, the machining operation stored in the area corresponding to the program number in step S15 is read into the machining data (see FIG. 15). , Input items required for each machining operation are displayed as blanks. This Figure 15 is (see Figure 6). This FIG. 6 corresponds to the screen for inputting data to the input items necessary for the machining operation.

Further, by inputting the data corresponding to the processing shown in FIG. 2 to each of the input items, the processing program for the step feed processing described above can be defined. Thereafter, when another machining program is desired to be input, the user can select and input a desired machining from the menu shown in FIG. 13 and repeat the input according to the display on the CRT 7.

When the input of all machining programs is completed, a predetermined key input indicating the end of the program is performed from the keyboard 6 to display the end of the program, and a series of machining programs are stored in the machining program storage area 3. It is stored in a predetermined program number.

The processing step of S15 functions as an item generating means for displaying the input items required for the machining operation on the CRT 7.

[Effects of the Invention] As described in detail above, in the present invention, after the machining operation such as the movement of the tool is input on the screen defining the machining operation selected based on the display of the display means, the machining operation is stored. In the screen for inputting data to the input items required for the machining operation when the machining program is stored in the second storage area of the means and then the machining program is created, the machining operation and the first machining operation stored in the second storage area are displayed. Based on the input items stored in the storage area of, the item generation means displays the input items necessary for the processing operation on the display means,
In an interactive data creation method in which data corresponding to the input item is input by the input means and stored in the third storage area of the storage means, the machining operation such as the movement of the tool is uniquely fixed. In addition, it is possible to easily define a desired machining operation with few input errors and also to easily input a machining program.
