The following data relates to a cam profile, in which follower moves with SHM during the lift & returning it with uniform acceleration & retardation,
acceleration being half the deceleration.
Minimum of radius of cam = 30mm
Radius of roller = 10mm
Lift of follower = 45mm
Offset of follower axis = 12mm
Angle of ascent = 70°
Angle of decent = 120°
Angle of dwell between ascent & decent = 45°
Speed of cam = 300 rpm
Draw the cam profile & determine velocity, maximum acceleration during lift.
