Abstract

The manufacturing information for a part is required for automated process planning, the link between CAD and CAM. Extraction of manufacturing features for a part from its CAD model is the first step in automated process planning. Most of the CAD models are transferred from one system to another through the neutral file format IGES. The software developed in C++ extracts both simple and concatenated features for prismatic parts from IGES files. The final results obtained are a set of manufacturing features along with their dimensions and positions, which can be used directly for downstream applications such as process planning, NC part programming and cutter path generation. The working of the system and algorithms used for feature extraction are explained with examples.
