This study deals with new planning method of tool posture for continuous 5-axis control machining with ball endmill. In conventional planning method, tool posture is planned before post processing phase without consideration about fixturing and kinematics of machine tool. So, it is difficult to achieve dynamic synchronous accuracy among rotational axes and translational axes in high speed machining. In the proposed method, in order to put a limitation of acceleration on each axis, we propose a new representation method for tool posture planning, called as Mercator/Machine Map (M-Map). M-Map is defined by 2-dimentional rectangular coordinates system and each axis corresponds to rotation angles of two rotary tables in 5-axis controlled machine tool. And, each domain on M-Map is colored by the state about collision between endmill and workpiece surface and positions of three translation axes. In this paper, we mention about definition of M-Map and fast calculation algorithm of M-Map based on performance of graphics hardware (GPU). The developed prototype system can estimate the M-Map at arbitrary point on cutter location within dozens of milliseconds.
