An end milling operation is being carried out on a 500 mm long and 80 mm wide aluminum alloy block to make a slot of 50 mm in width and 3 mm in depth. the cutting operation is done at a feed rate of 0.6 m/min. the cutter diameter is 50 mm, with 10 cutting inserts, and the tangential speed of the cutter is 50 m/min. calculate the material removal rate, cutting time, feed, and estimate the power required for cutting.

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

Aplate clutch has a single pair of mating friction surfaces 250-mm od by 175-mm id. the mean value of the coefficient of friction is 0.30, and the actuating force is 4 kn. a) find the maximum pressure and the torque capacity using the uniform-wear model. b) find the maximum pressure and the torque capacity using the uniform-pressure model.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false
