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.
