Abstract
The use of free-form or sculptured surface descriptions for computer-aided design applications has been proposed by numerous authors. The actual implementation of interactive sculptured surface description techniques for computer-aided design and manufacturing has been very limited. This paper describes an integrated approach to sculptured surface design and manufacture, and a software package for it on a five-axis NC milling machine. The integrated software consists of three parts: (1) surface description for generating the mathematical representation of sculptured surfaces, (2) path generation for approximating the surface representation into a sequence of linear cutter paths, and (3) tool control for generating the corresponding joint variable values.
