Now you can create many different types of cams such as linear, circular, and cylindrical cams.

Instead of disc cams that would only lift, grooved cylindrical cams of the type similar to those in machine tools and other machinery were utilized.

Cylindrical cams may also be used to reference an output to two inputs, where one input is rotation of the cylinder, and the second is position of the follower axially along the cam.

Cylindrical cams can provide motions that involve more than a single rotation of the cylinder and generally provide positive positioning, removing the need for a spring or other provision to keep the follower in contact with the control surface.

Abstract: This paper describes a computer-aided design and manufacturing system for design and machining of complex profiles for high performance cylindrical cams based on the B-spline and Bezier function representation of motion curves.
