TLDR
Research on algorithms for the generation of gouge-free, nonisoparametric 5-axis tool paths across composite surface patches is described, which includes the tesselation of the parametric surfaces into triangles.Abstract:
In theory, the 5-axis machining of sculptured surfaces offers many advantages over 3-axis machining, including faster material-removal rates, improved surface finish, and the elimination of hand finishing. In practice, 5-axis machining suffers from a number of drawbacks, which are mostly related to gouge avoidance. The paper describes research on algorithms for the generation of gouge-free, nonisoparametric 5-axis tool paths across composite surface patches. The approach includes (a) the tesselation of the parametric surfaces into triangles, (b) algorithms for the placement of a cylindrically shaped cutting tool onto the triangulated surface, and (c) interference detection and tool-position correction.read more

Ball-end cutter interference avoidance in NC machining of sculptured surfaces
Byoung K. Choi,Cha-Soo Jun +1 more
TL;DR: This paper is an algorithmic procedure that converts CC data (cutter contact points data) into interference-free CL data ( cutter location data) and automatically identifies ‘concave interferences’ as well as ’convex interferences' and then removes them.
