A CAM, with a minimum radius of 50 mm, rotating clockwise at a uniform speed, is required to give a KNIFE EDGE FOLLOWER the motion as described below :
To move outwards through 40 mm during 100° rotation of the cam ;
To dwell for next 80° ;
To return to its starting position during next 90°, and
To dwell for the rest period of a revolution i.e. 90°.
Draw the profile of the cam
(i) when the line of stroke of the follower passes through the centre of the cam shaft, and
(ii) when the line of stroke of the follower is off-set by 15 mm.
The displacement of the follower is to take place with UNIFORM ACCELERATION AND UNIFORM
RETARDATION. Determine the maximum velocity and acceleration during rise and return of the follower when the cam shaft rotates at 900 r.p.m.
