Abstract: To reduce the energy consumption of CNC machine tools,the optimization method of tool combination selection was presented towards NC milling process of 2.5D pocket.The influence of tool combination in terms of tool diameter selection and the accessible region determination on energy consumption of 25D pocket NC milling process was explicitly analyzed.A mathematical optimization model was established to select the best tool combination with objective of minimizing both energy consumption and machining cost of 2.5D pocket NC milling.A hybrid approach with integration of directed graph and Dijkstra algorithm was proposed to obtain the optimal tool combination.The proposed approach was demonstrated through tools selection of 2.5D pocket NC milling process and was verified to be efficient and effective.

Key words: NC milling, tool combination selection, energy consumption, 2.5D pocket
