Surface Interpolation Method for Numerical Control of Free-form Surfaces

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curved surface interpolation method for numerically controlling a free curved surface, and more particularly, to a curved surface interpolation method for a curved surface interpolation method for numerically controlling a free curved surface, And a method for use as a tool path for curved surface machining. At this time, considering the curvature of the curved surface, it is characterized by dividing the curved surface into a convex region, a concave region, and a planar region according to the shape of the curved surface to obtain an increase amount of parameter (? U) According to the curved surface interpolation method of the present invention, it is possible to solve the problems of the prior art that occur when curves are directly processed by using the curve formulas directly.
