Sheet 5Cam Design1)Draw the profile of a disk cam actuating a translating roller follower has base circleradiusrbof 40 mm and a roller radiusR= 10 mm. The rise angler= 120o. The upperdwell angleud= 30o. The return anglet= 120o. The lift is 30 mm. The motion ofthe follower is simple harmonic during the rise and the return. The amount of offseth= 15 mm opposite to the direction of rotation and the cam rotates in the anticlockwisedirection.2)Draw the profile of disk cam actuating an oscillating roller follower with thefollowing data:Base circle radiusrb= 50 mm.The rise angler= 120o.The upper dwell angleud= 20o.The return anglet= 120o.The maximum lift angle is 20o.The motion of the follower is parabolic during the rise and the return.The roller radiusR= 10 mm.The length of the followerL= 120 mm.The distance between the pivotsS= 120 mm.The cam rotates counterclockwise.
