複雑形状の深溝加工における旋回軸の動作を様に評価した工具姿勢計画手法

抄録

In the finishing of complex deep groove machining, we use 5-axis machine tools. At that time, posture planning in NC program generation, it has been done manually due to lead angle control in process, or rapid turning at the time of turning by round trip route in each surface inside groove. In our previous studies, we propose a method to automate by assuming the possible range of posture by the range of one pivot axis of machine tool and planning posture passing inside. In this method, we automation of posture planning without interference and realized continuous motion in machining on planning axis by planning in machine coordinate space. However, there was a problem that a rapid turning occurred on the other axis when feed turning. Therefore, in this report, we propose a method of minimizing the motion of the pivot axis by evaluating the motion of the other axis in the feed turning and selection the path with the minimum posture.
