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

A face-milling operation is being carried out on a 320-mm-long, 110-mm-wide, 50-mm thick annealed mild- steel block. The cutter follows a path that is centred over the workpiece and is applied on the top surface where it reduces the part thickness into 44mm. It has four teeth and is 150 mm in diameter. Cutting speed = 132 m/min, and chip load = 0.23 mm/tooth. Determine: Maximum metal removal rate during milling metal removal rate = _______________ ( ) Machining time...
