The paper presents a unified approach for the analytical design of three-dimensional cam follower systems. Generalized expressions for various cam parameters, such as the equation of the conjugate cam profile, the pressure angle at the point of contact and locations of the cutter and the grinding wheel axes are derived. The effectiveness of the proposed method is illustrated by applying it to camoids, three-dimensional cylindrical cams with translating and oscillating followers, globoidal cams with oscillating followers and two-dimensional disk cams with translating and oscillating roller followers.
