Draw a CAM PROFILE to drive an OSCILLATING ROLLER FOLLOWER to the specifications given below :
(a) Follower to move outwards through an angular displacement of 20° during the first 120° rotation of the cam ;
(b) Follower to return to its initial position during next 120° rotation of the cam ;
(c) Follower to dwell during the next 120° of cam rotation.
The distance between pivot centre and roller centre = 120 mm ;
distance between pivot centre and cam axis = 130 mm ;
Minimum radius of cam = 40 mm ; Radius of roller = 10 mm ;
inward and outward strokes take place with SIMPLE HARMONIC MOTION.
