FIG. 4 is a flow chart showing a process of generating an NC program by using the conventional automatic programming device for a coil spring forming machine described above, and forming a desired coil spring. Show. First, the pitch, wire material diameter, etc., which are parameters used for coil spring forming, are set (step S1), and then the number of coil turns, coil diameter, etc., which are data designating the shape of the coil, are set (step S2). An NC program is generated based on the parameters such as the set pitch and wire material diameter and the set shape data such as the number of coil turns and the coil diameter (step S
3) Then, the generated NC program is modified (step S4). Then, the finally determined NC program is operated (step S5), and all the processes are ended.
Thus, the NC program generated by the conventional automatic programming device for a coil spring forming machine cannot be operated as it is, and the NC program must be corrected without fail. For example, in the generated NC program, as shown in FIG. 7, the feed commands for all lines are G01 codes. However, in order to align the winding start portion and the winding end portion of the N20th line, the G code of the N20th line must be a G05 command having a skip function. Therefore, the operator needs to rewrite the NC program itself into the program shown in FIG. Therefore, the conventional automatic programming device for a coil spring forming machine has a drawback that the operator has to perform a troublesome work of modifying the generated NC program.

The present invention has been made in order to solve the above problems, and provides an automatic programming device for a coil spring forming machine which enables the spring forming operation as it is without modifying the generated NC program. The purpose is to provide.

According to the present invention, the correction contents to be applied to the NC program are preset as auxiliary operation data,
When converting the tool operation data to the NC program, the auxiliary operation data is reflected and the spring forming operation can be performed immediately.
Since the C program is generated, it is not necessary to modify the generated NC program.
