A slab-milling operation is being carried out on a block on a 200 mm-long, 150 mm-wide annealed mild steel block at a feed f= 0.20 mm/tooth and depth of cut d= 2.5 mm. The cutter is D= 45 mm in diameter, has 20 straight teeth, rotates at N=110 rpm and by the definition, is wider than the block to be machined. Calculate ; I.material-removal, II.estimate the power and torque required for this operation, III.calculate the cutting time
