SOLVED ANNA UNIVERSITY PROBLEMS ON SHAPING MACHINES AU Problem 3.1 A shaper is used to reduce the thickness of a L×B×D mm3. The starting dimensions of the part are L×B×D1 mm3. The cutting speed is v m/sec and the feed if ƒ mm/pass. The shaper ram is hydraulically driven and has a return stroke time that is n% of the cutting stroke time. An extra L1 mm must be added before and after the part for acceleration and deceleration to take place. Assuming the ram moves parallel to the long dimension of the part, how long will it take to machine, if the depth of cut is d mm? Given data: Work length, l = L mm Work width, w = B mm Work initial height, H1 = D1 mm Work final height, H2 = D mm Cutting speed, V = v m/s Feed, f = f mm /pass Approach + over run, A = L1 mm Depth of cut, d = d mm Return stroke time = n% of the cutting stroke time Solution:
