Abstract

The goal of automated process planning is to develop a realistic process plan for machining a part automatically, using 3-D CAD data as input. One of the issues of importance is the automatic determination of feasible tool approach directions for machining. This paper presents an algorithm to determine automatically feasible tool approach directions for machining holes. The part description is input in the form of a 3-D Boundary representation scheme. The algorithm is based on detecting if any faces of the part would obstruct the tool, if it approaches along a particular direction. Sample results are provided. The work represents a portion of an ongoing project to develop a CAD interface for automated process planning.
