Process Planning for Machining Centre Operations

摘要

The paper focuses on the process planning of prismatic workpieces. A Computer-Aided Process Planning (CAPP) system was developed that is capable of: creating machining phases (work elements), selecting cutting tools and machining parameters, sequencing the machining operations, and generating the NC-program for the machine tool. One of the central ideas in the project was to gather knowledge and expertise in a knowledge base. The tool selection is based on the knowledge. The major advantage of this kind of CAPP-system appears to lie in the production of one-of-a-kind and small batches where the share of process planning is large compared with mass production.
