Cams are well known for valving in internal combustion engines but are commonly utilized in industrial processes including stamping, food processing, and textile manufacturing. Most systems use an input torque in order to produce a linear force during the rise portion and rely on a spring to produce the return motion on the fall. Experiments using multiple test apparatuses suggest that the commonly used 30 degree pressure angle limit can be exceeded in low speed applications. Results also show that energy can be recovered from the system during the fall portion when the follower subjects the cam to a high return force. An analytical analysis describes the characteristics of how this return force can be recovered to increase overall system efficiency.","abstract_html":"A cam and follower system is a mechanical linkage designed to transform a rotating motion to that of a linear reciprocating motion.
