A New Methodology to Extract Machining Features From Prismatic Parts
نویسندگان
چکیده
Feature recognition systems are now widely identified as a cornerstone for conceiving an automated process planning system. Various techniques have been reported in the literature, but a few of them acquired a status of generic methodology. This research aims to exploit the concept of automatic feature recognition system. The boundary (B-rep) geometrical information of the part design is analyzed by a feature recognition program that is created specifically to extract the features from the geometrical information based on a geometric reasoning approach by using object oriented design software. A feature recognition algorithm is used to recognize different features of the part such as step, holes, etc. Finally, a sample application description for a workpiece is presented for demonstration purposes. Keywords—Feature Recognition, B-rep, Concavity/convexity.
