Design a cam to move a follower from 22 mm height to 15 mm height in 60, fall an additional 15 mm in 90°, rise to 22 mm height in 110 , and dwell for the remainder. Use a harmonic function for the rise and a constant velocity function for the fall. The shaft speed is 250 rpm. A) Create the cutoff pattern for the cam if it were to be cut using a laser. B) If a roller follower with a 20 mm diameter is used, determine the trajectory of the follower for programming in a cnc machine. This roller can also become a cutter and its trajectory can cut the cam. Cutter (roller follower) Laser cutter (knife-edge follower)

Transcribed Image Text:Design a cam to move a follower from 22 mm height to 15 mm height in 60 , fall an additional 15 mm in
90°, rise to 22 mm height in 110 , and dwell for the remainder. Use a harmonic function for the rise
and a constant velocity function for the fall. The shaft speed is 250 rpm. A) Create the cutoff pattern for
the cam if it were to be cut using a laser. B) If a roller follower with a 20 mm diameter is used,
determine the trajectory of the follower for programming in a cnc machine. This roller can also become
a cutter and its trajectory can cut the cam.
