Abstract
A method for generating offset surface data representing a tool path of a tool traversing patches which are mutually adjoining at boundary lines where there is no continuity of the osculating planes. The offset surface data is interpolated for the parts of the surface at which the offset surface data become mutually discontinuous at the boundary lines or for a patch having a sharp corner. The present invention is applicable to a NC (Numerical Control) machining center which can control a machine tool so as to prevent excessive milling by the tool at the discontinuous parts of the offset surface.
