<p>A method of preparing NC data for machining the interior of a region, wherein a counter profile (CNT1, CNT2) input for specifying the region (ARM) are drawn on a graphic display (106), a tablet (108) is operated to recognize the region (ARM) instructed by the graphic cursor and to apply a predetermined color to the interior thereof, a linear region (ARl) having a tool width defined by coupling the machining start point (PS) and the machining end point (PE) instructed by the graphic cursor is no more colored, the above machining end point is used as a next machining start point, the next machining end points are input successively, and the tool moves linearly along the finally instructed machining start point and the machining end point to machine the interior of the region (ARM).</p> |
