Method for determining whether solutions of three-dimensional machining functions can be figured out by an algebraic method or an analytic method

摘要

Functions in various kinds of forms, whether to be rational functions or not, to express a plurality of curved surfaces are unified into a set of functions with respect to parameters u and v by an algebraic method or an analytical method. Based on the set of functions, intersections which are necessary for machining of the curved surfaces are calculated, and paths of a cutting tool to machine the curved surfaces are determined.
