ABSTRACT:
An object of the present invention is to provide a practical method for machining a sculptured surface. One of the characteristics of a concrete method for machining a sculptured surface so as to accomplish the object is that a patch table of a sculptured surface as surface information data for sculptured surface machining is configured so that a tool path can be generated using the inverse offset method for various surfaces such as a Bezier surface or a Ferguson surface and another characteristic is that over cutting during tool path generation on the basis of the inverse offset operation can be corrected.
