The Heriot-Watt FeatureFinder: A Graph-Based Approach to Recognition

Abstract

Abstract This paper describes the functionality of a Feature Recognition system, known as FeatureFinder. The system’s algorithm has been developed from a graph-based approach to feature recognition and is now capable of identifying a variety of features on a wide range of machined components. The system has been designed to be used within a solids machining package and identifies features from a specified tool approach direction. The paper details the result of applying the algorithm to the CIE97 test pieces. Features are identified on all of the components and the paper concludes with a brief description of on-going work designed to extend the range of components FeatureFinder’s algorithm can analyse.
