| Abstract: | With the development of Intelligent NC programming technique,it is getting more and more popular to use stock-remaining model in NC machining system.The article points out the importance of the stock-remaining model in NC programming technique.As a geometric model used in machining,both the advantages and disadvantages of Z-Map model are analyzed in the article.Specially,against the disadvantage that data comprised Z-map model is too vast,an efficient algorithm of simplifying Z-Map model using errors in Z direction is presented and a data simplified stock-remaining model is built.In addition,how to apply the simplified stock-remaining model to speed up tool path simulation,generation and optimization is discussed. |
