One plate (fluency effort 520 psi) is 2 in. Thick, 10 in. Wide, and 12 m long. The thickness is reduced in three steps of hot rolling. Each step will reduce the slab to 75% of its previous thickness. For this metal and this reduction, a widening of 3% is expected in each step. If the speed of entry of the plate in the first step is 40 feet / min and the speed of the roller is the same...

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...
