<p>A method of preparing a program for rough working, wherein a block of NC data outputted by a working program for performing the rough working of a regional cutting is reduced so as to shorten time for the rough working. At a cut ending point (3) of a material to be worked on (1), a further one cut-in of an instructed depth is performed, and a regional cutting is performed in the reverse direction from the cut ending point (3) to a cut starting point (4). Accordingly, a block of NC data outputted can be reduced. Furthermore, outputs of NC data for performing a rapid return from the cut ending point (3) to the cut starting point (4) are eliminated, so that time for the rough working can be shortened. <IMAGE></p> |
