                       follower types. Figures 16.2.2 and 16.2.3 show that cam–follower pairs may be used not
                       only for exchanging types of planar motion but also for converting planar motion into
                       three-dimensional motion.
                        In the following sections, we will direct our attention to planar rotating cams (or radial
                       cams) with translating followers as in Figure 16.2.4. Initially, we will consider common
                       nomenclature and terminology for such cams.

                             with Translating Followers
                       Consider a radial cam–follower pair as in Figure 16.3.1 where the axis of the follower shaft
                       intersects the axis of rotation of the cam. Let the follower shaft be driven by the cam
