ABSTRACT:
A NC system which is provided with a three-dimensional automatic programming function which comprises a shape data input unit which can input various kinds of shape data including free surfaces, a shape extraction process which obtains a distance from arbitrary position data corresponding to a function which represents a shape in a real space as well as a parametric space for conducting set operations with object structure data on said shape, and a tool path generating unit which generates a trace of a tool base upon the whole shape data inputted from said shape extraction processor.
