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...
