ABSTRACT:
A machining region which is determined from an inputted before-machining shape and an inputted after-machining shape is divided and the divided machining regions are united to form a united machining region. An optimum machining process is obtained by selecting an optimum combination of the machining regions based on parameters set in advance, and determining a machining method for the united machining region. That is, a numerical control information generating apparatus generates numerical control information by determining a machining method from a before-machining shape and an after-machining shape by generating a machining region from the before-machining shape and after-machined shape, judging pattern elements forming an angle to a Z-axis of more than a predetermined value among a series of pattern elements constituting the generated machining region, dividing the machining region by lines which are parallel to the Z-axis and each pass through a corresponding starting point of a judged pattern element and lines which are parallel to the Z-axis and each pass through a corresponding end point of the judged pattern element region, and uniting divided machining regions based on predetermined parameters so as to determine a machining method for the united machining region.
