Interactive Cam Mechanism Design - Sample Translating Follower

This is a sample translating cam design with pre-specified input parameters in the input dialogboxes. Following is a list of variables definitions :

Base Radius -- Initial radius of the cam
Follower Offset -- Distance from the cam center to the follower.
Profile Points -- The number of points used to calculate the cam profile.
Cam Angular Velocity -- The rotational velocity of the cam. Positive clockwise.
Cutter Radius -- The radius of the CNC mill cutter
Cutter Length -- The length of the CNC mill cutter
Cam Thickness -- The thickness of the cam and the depth that the cutter moves to
Feedrate -- Feedrate for machining
Spindle Speed -- Spindle Speed of the cutter
X-Y-Z Offset -- CNC home position offsets
Duration -- duration of a section [deg]
Lift -- Change in the displacement of follower for a section
Motion -- [harmonic/cycloidal] Follower motion, shape of displacement curve.
