FIG. 7 is a flowchart explaining the operations of FIGS. 5 and 6.

Next, the operation will be explained using flowcharts shown in FIGS. 5, 6, and 7. To display the machining trajectory (3) on the CRT display device (6), first, in step (6a), the CRT coordinate origin (
2) is set for the CRT display device (6). After setting as described above, in step (6b), the NC program of the machining trajectory (3) to be displayed on the CRT display device (6) is read. Next, the N read in step (6c)

The machining trajectory (7) of the enlarged NC program shown in FIG. 6 can be displayed on the CRT display device (6) by the same operation as the display.

[Problems to be Solved by the Invention] Since the conventional machining trajectory display method of the NC device is configured as described above, only one machining trajectory (3) is always displayed on the CRT display device (6). However, even if there are several positions to be enlarged, each position must be specified and displayed once, which is a waste of time. In addition, there is a problem that it is not possible to view several places at the same time, and at the same time, when redisplaying after enlarging, the position in the whole that was specified for enlargement disappears, making it difficult to understand the overall shape, and starting again from the beginning of the machining trajectory (3). There were issues such as the need to display the entire picture.

This invention was made to solve the above-mentioned problems, and the machining trajectory can be displayed at several locations at the same time.
It is an object of the present invention to obtain a method of displaying a machining trajectory of an NC device in which an entire image of the machining trajectory is also displayed at the same time.

[Means for Solving the Problems] A machining trajectory display method for an NC device according to the present invention simultaneously processes the scale values of several partially enlarged machining locus locations and continuously displays them on a display device, and The scale value of the entire image for the machining locus is also processed so that the machining locus of the entire image can also be displayed.

Since it will be displayed,
It is made clear where in the whole the partially enlarged position corresponds. It has also been partially enlarged. In particular, by displaying the part FlfiJ that is the object of attention along with the overall shape, it becomes possible to recognize the machined shape all at once in a short time.
