To solve the problem in designing a cam mechanism with its follower making a complicated planar movement, according to the equations of cam profile and expression of pressure angle of cam mechanism with its follower making a complicated planar movement, this article introduces a method by which the strong calculating functions of MATLAB are used to compute parameters, draw cam profile and simulate the motion in designing cam mechanism. It can be judged whether the running of the mechanism is accordant with its design by simulation of the cam mechanism to assuring the design's accuracy. This method has the features of high accuracy, rapid and convenient functionings.
