A slab-milling operation is carried out on a high-strength steel block that has a specific energy of 1.3 hp*min/in3, a length of 20 in, and a width of 6 in, at a feed of 0.01 in/tooth and a depth of cut of 0.15 in. The cutter rotates at 150 rpm and has a diameter of 3 in with 8 straight cutting teeth. Calculate the material removal rate and the cutting time, and estimate the power required.
