This paper presents a parametric design method of the cam profile curve with“law curve”function of NX8.0,analyzes the continuity of the cam profile curve and verifies the correctness of the design through the cam motion simulation. Through the analysis of the displacement and velocity motion laws of the fol ower,the parametric drive of the cam design is verified. The result shows that the CAD and CAE module of NX8.0 can is used for the parametric design and motion analysis of the cam profile curve to ful y guaran-tee the design accuracy and greatly improve the editability and reusability of the model.
