| Abstract: | A group of methods for accurately generating tool paths based on Accurate TrimmedSurface Model(ATSM) are introduced.A kind of data structure of ATSM is constructed in order to generate tool paths based on new concepts instead of those based on discrete surface models.Applying the method of trimming surface to tool path generation,two systems for tool path generation and plan are proposed.One is based on parametric space and the other is based on three-dimensional space.A method base for generating tool paths based on ATSM is brought forward. |
