CAM PROFILE WITH KNIFE EDGE FOLLOWER
A disc cam is to give SHM (Simple Harmonic Motion) to a knife-edge
follower during outstroke of 50mm. The angle ascent is 120, dwell 60, and
angle of descent 90°. The minimum radius of the cam is 50mm. Draw the profile
of the cam when the axis of the follower passes through the axis of the
camshaft.
Calculate the maximum velocity and acceleration during ascent and descent
when the camshaft revolves at 240 rpm.

Design a cycloidal cam-follower displacement table for a cam that provides a dwell at zero lift for the first 120 of the motion cycle and then dwells at 0.8 in lift for cam angles from 180 to 210. The follower will again dwell at zero lift at 270 for the remainder of the cycle. The cam follower displacement table will be laid out using 10 intervals. Assume the cam rotates at constant angular velocity. 4.
