According to theory of surface meshing, the computing method of globoid cam rate and contact stress of the complex globoid cam mechanism is researched here with the rotating matrix operators and differential geometry theory. Generalized expressions for the parameters of the cam mechanisms including the relative normal curvature equation and the stress equation at the point of contact are derived and modified. Also this paper uses the computer to illustrate the graph of the relative normal curvature and a case is given in the end.
