In recent years, 5-axis control machining has attracted a wide attention because of having many advantages compared with 3-axis control machining. However, there have been few roughing procedures corresponding to 5-axis control machining. This study especially deals with roughing by 3+2-axis control machining, which performs 3 translational axes machining after determining a suitable tool axis vector by 2 rotational axes movement. For 3+2-axis control machining, the determination of tool axis vectors, tool lengths and tool diameters largely affects the rough machining time. The previous study proposed a method of determining the optimal tool axis vectors and selecting the tool diameters for efficient roughing. In order to improve the method more effectively, this study proposes a new method of searching optimal tool combinations by taking account of shorter tool length. Stiffness of short tool is so high that it can machine workpiece more efficiently. The effectiveness of the proposed method was demonstrated by the machining simulation and experiment.
