摘要
特征识别是CAD与CAPP以及CAM之间的智能化接口,对实现CAD/CAPP/CAM有机集成具有重要意义。一方面,国内外研究成果颇多;另一方面,由于特征识别具有相当难度,至今仍然存在许多问题有待解决,因此,它一直是CAD/CAM领域的研究热点。本文对特征识别的现状进行了较全面的阐述。分门别类地介绍了各种具有代表性的特征识别方法。最后对目前特征识别研究中存在的问题以及可能的解决方案进行了讨论。
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.
