| Abstract: | In this paper, the collision and interferencedetection algorithm based on B-Rep used for numericalcontrol machining process simulation is present. The algorithm solves the problems in numerical control machining, such as overcutting, undercutting, tool coming intocollision with the pallet and fixture, tool bruising theworkpiece surface. Several experiments show that theproposed algorithm has the advantages of fast operationand high detecting efficiency. |
