Aperipheral milling operation is performed on the top surface of a rectangular workpart which is 400 mm long and 60 mm wide. the milling cutter, which is 80 mm in a diameter and has five teeth overchanges the width of the part on both sides cutting speed = 70 m/min, chip load = 0.25 mm/tooth, and depth of cut = 5.0 mm.

determine
(a) the actual machining time to make one pass across the surface and
(b) the maximum material removal rate during the cut

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
