[Problems to be Solved by the Invention] Since the conventional automatic programming device is configured as described above, when inputting the shape data of the target shape, for example, the shape shown in FIG. As shown in Figure 4, in addition to straight line and circle data as input information,
There is a problem in that two data items, one for the traveling direction of the straight line and the other for the rotating direction of the circle, must be input at the same time, which increases the burden on the operator.

This invention was made in order to solve the above-mentioned problems, and aims to provide an automatic programming device that can reduce the burden on the operator by eliminating the extra effort when inputting the target shape. purpose.

[Means for Solving the Problems] The automatic programming device according to the present invention creates numerical data of a target shape in a shape data construction means based on input shape data, and creates numerical data of the shape data construction means.
