Abstract
A plurality of curved surfaces which have distinct characteristics are defined as a unified curved surface. The definition is made by a group of polynomials with respect to parameters u and v in two directions reflecting the characteristics of the curved surfaces. Then, paths of a cutting tool to machine the unified curved surface are generated by using the polynomials. Further, a curved surface is divided by a curve into two regions, and a point is designated in one of the regions. Only with respect to the region which includes the designated point, paths of the cutting tool are generated.
Claims2
A three-dimensional machining method for machining a workpiece three-dimensionally, the method comprising the steps of:
- inputting data about a plurality of curved surfaces which have distinct characteristics;
- defining the plurality of curved surfaces, based on the inputted data, as a unified curved surface defined by a group of polynomials with respect to parameters u and v as follows:
- ##EQU4## calculating a surface to be machined from the curved surface defined by the group of polynomials;
- and
- machining the workpiece to create the calculated surface.
