follower.
The spherical cam (Fig. 1.18) has a rotating portion of a sphere, which oscillates a fol-
lower having its axis perpendicular to the cam axis. This cam represents the limiting case
of a conical cam. The realms and restrictions of the spherical cam are similar to that of
the conical cam.
The three-dimensional (3-D) cam or camiod (Fig. 1.19), which has a curved face,
both rotates about the longitudinal axis and moves relative to the follower along this
