| Abstract: | The study on the manufacture of spatial cams with unequal diameter cutters is of the practical demand. The method of off-set compensation for tool path is thought important due to its high work efficiency and low cost. The fact that there must be theoretical errors in the manufacturing method of off-set compensation for tool path is proved theoretically in this paper. The basic idea of this method is also discussed. Then a mathematical model of profile analysis of spatial cam in this method is deduced and the algorithm for NC machining is given in the end. |
