Cam and follower surfaces in line contact are considered. The general equations of curvature analysis for a 3-link cam-follower mechanism are based on the layout of the general coordinate systems, the matrix method, the basic kinematic relationship of contact surfaces, and the definitions of limit functions. For the given input-output relation and generating surface, the principal curvatures of the generated surface, the relative normal curvatures, and the undercut are expressed in concise form and can be applied to all planar and spatial cam-follower mechanisms. Three applied examples are given.
