Abstract

To acquire better applications for the rotary method

the multi-point contact property is deeply analyzed

the concept of the characteristic point and the characteristic parameter curve are presented. Then the characteristic parameter curve tool path planning method is developed. The essentiality is determining the optimal tool positions of the toroidal cutter to make the left characteristic parameter curve of the next path being collinear with the right characteristic parameter curve of the current path under the given precision by iterative computation. Finally

the tool paths are completely arranged. An example shows that the characteristic parameter curve tool path planning method enables to generate the smooth and interfere-free tool paths and improve the actual machining efficiency because it gains the advantages of machining strip width over iso-parametric method.
