The cutting processes in milling and drilling are simulated to design tool geometries for the machining operations on machining centers. The presented simulation predicts the cutting force and the chip flow direction based on an energy approach, which interprets the chip flow model in three-dimensional cutting process as a pile of orthogonal cuttings. A milling process with a tilted tool is shown to verify the simulation in the machining operation on the multi-axis machining center. A drilling process is simulated to show the change of the cutting force and the chip flow direction in machining of a hole on a plate. Because the energy approach can be applied to the machining processes with the diversified tool geometries using only the orthogonal cutting data, this paper discusses the effect of tool geometry on the cutting process. A parametric study is tried to improve the geometry on the chisel of the drill.
