The traditional method to find the profile surface of a cylindrical cam from a given pitch curve, for its theoretical error, cannot be applied in accurate control situation. The mathematic model of the profile surface of a cylindrical cam with spherical\|faced follower was investigated. An iterative method and direct method using root\|finding formula of four algebraic equation were educed. The analytical method, without theoretical error, is an accurate one to solve the problem.
