Question
Transcribed Image Text:Q1/ Draw the profile of a cam operating a knife-edge follower (when the axis of the follower passes
through the axis of cam shaft) from the following data:
(a) follower to move outward through 30 mm with simple harmonic motion during 120° of cam
rotation,
(b) Follower to dwell for the next 60°,
(c) Follower to return to its original position with uniform velocity during 90° of cam rotation,
(d) Follower to dwell for the rest of the cam rotation.
The least radius of the cam is 20 mm and the cam rotates at 240 rpm. Determine the maximum
velocity and acceleration of the follower during outstroke and return stroke.

- 1. A cam must rise in 3 seconds at constant velocity of 0.25 in/sec in the first segment. Then the follower must return to the zero position in 5 seconds with a full return cycloidal motion and then dwell for 3 seconds in segment 3. The final segment will be a full rise cycloidal motion. The total cycle time is 12 seconds, and the maximum height is in the first segment.

The follower then return to its original position through an angle 0R and then dwell for the rest of the cam rotation of 110°. The displacement of the follower is to take place with constant speed motion during both the outward and return strokes. The least radius of the cam is 4 cm.
