The Fundamental Law of Cam DesignAny cam designed for operation at other than very low speeds must be designed with the following constraints:
The cam function must be continuous through the first and second derivatives of displacement across the entire interval (360 degrees).
Corollary:The jerk function must be finite across the entire interval (360 degrees).

where h is the total rise, or lift, θ is the camshaft angle, and β is the total angle of the rise interval.

Combined functionsDynamic force is proportional to acceleration. To minimize dynamic forces,
should minimize the magnitude of the acceleration keep it continuous.
Kinetic energy is proportional to velocity squared.
We also would like to minimize stored kinetic energy,
