(3) Draw the cam profile for following conditions:ДЇollower type = roller follower, in-line lift = 25mm base circle radius = 20mm roller radius = 5mm out stroke with UARM, for 120 0 cam rotation dwell for 60 0 cam rotation return stroke with UARM, for 90 0 cam rotation dwell for the remaining period. are tangential to the offset circle of 10mm dia. (2) Draw the cam profile for the same operating conditions of problem (1), with the follower off set by 10 mm to the left of cam center.Дisplacement diagram: Same as previous case.Д¬am profile: Construction is same as previous case, except that the lines drawn from 1,2,3вЂ¦. acceleration during return stroke = ar max = acceleration during outstroke = ao max = rП‰ 2 p (from d3) = velocity of follower during return stroke =, vr max = velocity of follower during outstroke = vo max = This forms the required cam profile.ДЄngular velocity of cam = 104.76 rad/sec

Transfer points a,b,cвЂ¦.l from displacement diagram to the cam profile and join them by a smooth free hand curve. Mark points 1,2,3вЂ¦.in direction opposite to the direction of cam rotation. velocity and acceleration during out stroke and return stroke if the cam rotates at 1000 rpm in clockwise direction.Д¬am profile: Construct base circle. Follower type = Knife edged, in-line lift = 50mm base circle radius = 50mm out stroke with SHM, for 60 0 cam rotation dwell for 45 0 cam rotation return stroke with SHM, for 90 0 cam rotation dwell for the remaining period.
