Introduction
Success in metal cutting depends on the selection of the proper cutting tool, both _ and _, for a given work mate
ME 312, Solutions to HW # 7 8.1 (1) Increasing the depth of cut means more material removed per unit time. Thus, all other parameters remaining constant, the cutting force has to increase linearly because the energy requirement increases linearly. (2
