This paper proposes a cam curve synthesis method based on classical splines. The cam curve is described by the classical spline of order 6. Corresponding equations and boundary conditions are given to satisfy the specific requirements of the cam design problem. Then, a universal computation method is given and an example to illustrate the effectiveness of the proposed method is presented. It is shown that excellent design result can be gained easily, and the designer can adjust the interpolation values of the interior knots of the spline to change the cam curve in a local influence without any violation of the specific constraints.
