Abstract

A key activity in developing a process plan for machined parts is the planning of machining setups. This paper deals with the automatic generation of multiple machining set-ups given a feature-based part description. A hybrid object-oriented and rule-based approach is proposed to represent the declarative and procedural planning knowledge. Declarative knowledge is employed to identify machining feature groups. Procedural knowledge regarding machine tool capability, feature precedence and fixture interaction is used to generate machining set-ups. The paper presents a set-up planning system based on the proposed approach. The system is for prismatic parts produced on a three-axis vertical mac
