This paper proposes general expressions describing the instanteous kinematics of spatial cam mechanisms, such as transformation matrices, relative velocity matrices, and relative acceleration matrices. Based on screw axes, manipulation of matrix methods, and general coordinate systems, these matrices are derived. Using these matrices, the relative velocity and the relative acceleration between the cam and the follower are obtained easily. The concise expressions for the description of kinematics can be utilized to all special spatial cam mechanisms, including planar cam mechanisms. Two examples are given.
