Abstract

A numerical control apparatus allows for the machining of a workpiece based on a three-dimensional work shape which is inputted. The shape of the workpiece is set and the shape of the workpiece and three-dimensional work shape determine the work region to be extracted. The extracted work region is divided into work regions of spot work, contour work, and region work by the characteristics of the work. The work order is set to determine the order in which the divided work regions are to be machined. The work information for each work region is then inputted and command data used in moving a tool is generated from the work order data and the work information.
