The corresponding coordi nate points, which can be calculated by sample programming of MATLAB language and the curves and surfaces is gen erated by using curve command in Pro/ E4. 0.T hen the surfaces can be merged and materialized by materialized com mand. Compared with the present programming methods, this method has the follow traits as simple and easy to under stand, convenient to design, good generality, and can significantly improve the efficiency of globoidal cam 3D model ing.
