Interactive Cam Mechanism Design - Sample Oscillating Follower

This is a sample osciallating 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 -- The follower face offset measured from the follower pivot point
Distance between Cam and follower -- Distance from the cam center to the follower pivot point
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]
Osciallating Angle -- Change in the follower osciallating angle in a section [deg]
Motion -- [harmonic/cycloidal] Follower motion, shape of the displacement curve
