The roller follower of a cam moves with SHM during ascent and with uniformly accelerated and decelerated motion during descent. The cam rotates at 370 rpm. Draw the cam profile for the following
Data:
Least radius of cam = 60 mm
Angle of ascent = 54°
Angle of dwell between ascent and descent = 48°
Angle of descent = 66°
Lift of follower = 50 mm
Roller dia = 30 mm
Offset = 20 mm
Determine the maximum velocity and acceleration of following during descent.
