The Status and Problems of Feature Recognition and Its Solutions

Feature recognition is the intelligence interface among CAD,CAPP and CAM.It plays the important role in realizing the CAD/CAPP/CAM integration.On one hand,there are lots of research production in domestic and overseas;on the other hand,owing to the difficulty of feature recognition to some extent,there are still many problems need to solve.Therefore,it is always a research hotspot in the domain of CAD/CAM.The history and current status of feature recognition was surveyed.The representative feature recognition methods were classified and introduced.The existing problems and possible solutions in feature recognition were discussed.
