| Abstract: | Features is one of the difficult problems for CAPP system development,especially in intersecting feature recognition and complex feature recognition.The paper proposes a method to realize part feature recognition and extraction based on NX synchronous modeling technology.The volume change of each step in the processing of a part from its blank to finished part can be identified using feature-based modeling system that adopts synchronous modeling technology,size-driven and constraint-driven technology,and removal volume decomposition that can resolve intersecting feature recognition problem.Thus,parametric or incompletely parametric part feature identification can be realized and its manufacturing information can be obtained. |
