camdiameter
Camdiameter is a term used in cam mechanisms to denote the diameter of the driving cam surface that engages the follower. In radial and cylindrical cams, this diameter establishes the scale of the follower’s motion and the basic contact geometry between the cam and its follower.
The exact meaning of camdiameter varies by author and industry practice. In many classical references, camdiameter
Relation to design and analysis: The base radius rb = camdiameter/2 defines the reference circle from which
Measurement and design practice: In CAD models, camdiameter is specified as the base circle diameter, with the
