Assume that in the face-milling operation shown in Fig. 24.6 the workpiece dimensions are 100 mm by 250 mm. The cutter is 150 mm in diameter, has eight teeth, and rotates at 300 rpm. The depth of cutis 3 mm and the feed is 0.125 mm/ tooth. Assume that the specific energy requirement for this material is 5W • s/mm* and that only 75 % of the cutter diameter is engaged during cutting. Calculate
(a) the power required and
(b) the material-removal rate.
