Abstract:A new model for parametric surface digitization is presented and the criterion to be used to control the accuracy is described. Based on this model, a new method of tool path generation for NC machining of parametric surfaces is developed. Different from currently used ones, this method makes it possible to obtain the cutter contact points by intersecting the digitized surface net with the section plane, and is found to be more reliable in accuracy control and the computation is of higher efficiency and flexibility.
Keywords:NC machining  tool path generation  parametric surface digitization
