It is required to design a disk cam with a flat-faced follower. The follower is to rise a height of 60 mm in 140, followed by a dwell for 60, a fall over 120 and finally a dwell at datum for the remaining 40 of cam rotation. The cam rotates uniformly at 200 rpm. It is desired to have a smooth operation of the follower without any acceleration at both ends of rise and fall periods. The cam angle scale 1 cm: 30 of cam rotation and the displacement scale: 1cm: 10mm. Select a suitable type of motion for the rise and fall periods from the table below. Draw schematic diagrams ONLY for the follower displacement, velocity, acceleration and jerk. Determine the maximum follower velocity and the corresponding cam angle. Determine the maximum follower acceleration and the corresponding cam angle.
