Abstract: The design Procedure described in this paper consists of: 1, Selection of a virtual acceleration curve represented by a series of numerical values ( α mm)　with arbitrarily presc-ibed shape according to working requirements of the cam follower; 2, Selection of incremental cam angle according to the desired and attainable accuracy of　contour fabrication; 3, adjustment of the above virtual curve so that it will satisfy certain given requirements or　boundary conditions of the follower during its stroke. Various follower boundary conditions are　grouped into four classes. For each class an equation for adjustment is derived; 4, Calculation of the unknown scale factorαa mm/s=/mm(actual acceleration A in mm/s2 =μaα) and the required cam profile by substituting in a set of equations derived for each class of boundary conditions A historical review about this topic and an example for approving design formulas are placed at the beginning and ending of this paper.
