Effect of Tool's Dimensional Variation on Machining Accuracy of Cylinder Cam with Oscillating Follower

For the cylinder earn with the oscillating follower, by using the spatial meshing theory, the novel machining method, an optimal control method, is introduced, by which the normal profile error of the cylinder eam arising from the dimensional variation of the tool approaches to the minimum scale, The accurate formula of normal profile error of the cylinder earn is derived through the determination of the cross point of the normal of the practical profile and the theoretical curve surface of the cylinder earn, In the meantime, the simple formula to calculate the normal error's approximate value is introduced,
