Process Plan Cases Retrieval Approach Based on Part Characteristic List and Key Machine Tools
Zhigang Yang · Computer Integrated Manufacturing Systems · 2003
The process plan case retrieval is the key procedure in Case Based Reasoning (CBR) CAPP system. In order to retrieve process plan cases quickly and effectively, a case retrieval approach based on part characteristic list (PCL) and key machine tools is presented. The whole retrieval procedure is implemented though two steps. The first step retrieved the cases by use of the PCL and the optional second step is designed to get the smaller case set by use of the heuristic key machine tools information. The part characteristic list is defined, and its building method is addressed. The algorithm for each retrieval step is discussed in detail.
