Extraction of Manufacturing Features from an I-DEAS Universal File
I-DEAS, a Computer Aided Design (CAD) software package, generates a Universal file containing geometry and topology information of objects. The Universal file also has the history of boolean operations resulting in an object. This paper presents a scheme for extracting manufacturing features from the Universal file. The feature extraction technique is based on rules such as a boolean difference of a cylinder and a block, at the proper position, results in a hole. The paper presents an example of generating manufacturing features for machining applications.
