Abstract
The general algorithm for manufacturability analysis of 5-axis sculptured surface machining is presented. The visibility cone which represents the aggregate of all visible directions is constructed to describe geometric constraints. Combined with the convex hull computation algorithm, a detailed procedure for computing the visibility cone has been developed. Through the geometric constraint analysis, the manufacturability for sculptured surface machining is evaluated so that geometric defects and inefficiencies can be inspected and corrected at the earlier design stages. Hence reworks in product development can be reduced or even avoided and the concurrence of sculptured surface design and manufacturing can be enhanced.
