Abstract

We present several algorithms for computing a feasible toolpath with desired features for sculpting a given surface using a 5-axis numerically controlled (NC) machine in computer-aided manufacturing. A toolpath specifies the orientation of a cutting tool at each point of a path taken by the tool. Previous algorithms are all heuristics with no quality guarantee of solutions and with no analysis of the running time. We present optimal quality solutions and provide time analysis for our algorithms. We model the problems using a directed, layered graph G such that a feasible toolpath corresponds to a certain path in G, and give efficient methods for solving several path problems in such graphs.
