Using Pattern Matching technique for feature recognition of STEP file

Abstract

This project utilizes the pattern matching technique for feature recognition of STEP file. It is proposed as an input for automatic feature recognition in the Computer Aided Design and Manufacturing (CAD/CAM) application. The project explores the pattern matching technique for feature recognition of part especially from B-Rep data structure. This method accomplish their task based on recognition of features as pattern made up topological entities such as face, edges, and vertices. It will easily recognize isolated features and simple interacting features. That technique used standard for the exchange of product information (STEP) formats for geometrical data extraction representation to matching that the coordinate from the STEP file to decide the correct surface part in the design.
