Feature Recognition Module of the CAPP System

Design CAPP system based on artificial intelligence is one of the most interesting problems. Solving this problem allows manufacturers reduce time to make a decision and more precisely estimate costs and possibility of part production. The system can be divided into different modules, like a feature recognition module, knowledge base, and so on. One of the main problems of automatized CAPP system is an inner information about parts. Manual entry of information makes this system very inconvenient to use and the right way is importing data from the CAD system. The inner information of this module is a 3D model of a part, which consists of parameters: geometry, tolerance, material and etc. The first reason for this complexity is a huge range of parts and features with different types and parameters. Authors in this article describe and compare the main approaches to design feature recognition module of CAPP system based on modular approach.
