A Case Retrieving System for Machining Processes of Axisymmetricparts based on Geometric Indexing and Process Hierarchicalstructure

Abstract

To develop a new machining process plan in the competitive global market, one effective way is to retrieve a relevant casesimilar to the new desired case and then adapt it to meet the newsituations. This paper proposes a retrieving system for processplanning cases from two aspects the representation and manufacturing processes of a part. The core of the retrieving systemcontains 1) the feature-based representation of a part, 2) indexing of a part based on two-dimensional peripheral indexing andfeature indexing, 3) a hierarchical structure of cutting processesfrom part cutting history, 4) a similarity metric. The similaritymetric is used to measure the similarity between the new desiredpart and one old case based on the indexes of the parts. The application domain here is the process planning for axisymmetricparts. The proposed retrieving system is implemented in a Sunworkstation using ACIS 3D-Toolkit and C++.
