Abstract: In order to minimize the normal errors of the profile of the
cylinder cam, that are brought in by tools' radial errors in the
machining process, a new machining method, optimal control
method, is introduced. Taken the cylinder cam with rectilinear
translating and conical roller follower as an example, the
normal errors of the cam profile arising from the optimal
control machining process is discussed by using spatial meshing
theory, and a simple and concise approximate formula to
calculate normal errors is given. The comparison between the
normal errors, arising from the optimal control machining
process and conventional two-axes coordinated machining process,
respectively, shows the optimal control method is of the great
application value.
