The reciprocating radial roller follower of a cam is to rise 3 cm with a Simple Harmonic Motion (SHM) in 120°, dwell for 60°, then return with a cycloid motion to its starting point in 120°, and finally dwell for the remaining 60°. If the prime-circle radius is 3 cm, draw the displacement diagram, and then the cam profile for clockwise cam rotation (if the roller-circle radius is 0.5 cm).
You are given a task to design a cam. The cam are used for feed mechanism in automatic lathe machine. The motion of the cam follower that you need to design are given as follows: (b) 1. Move up 50 mm in 1 second using the harmonic motion 2. Dwell for 0.5 s 3. Move down 50 mm in 1 second using the harmonic motion 4. Dwell for 1 second The motions of the cam follower then will repeat the same sequences. (i) Calculate total time taken for the cam to complete a full circle motion. (ii) Calculate the rotational speed of the cam. (iii) Determine the cam rotation angle for each of the follower motion interval. (iv) Construct the follower displacement diagram for this cam
