The uses of features have been considered to be the technology which bridges the gap between Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) in the CIMS (Computer Integrated Manufacturing Systems).Active research in the last two decades has resulted in a number of recognition techniques like rule based, graph matching, volume decomposition, hint based, neural network, etc. This paper presents the development of distorted CAD objects recognition system. A well-known Multi-Layer Perceptron (MLP) neural network with backpropagation learning algorithm is chosen for its fast processing time and its good performance for feature recognition problems.
