研究了五轴数控加工中刀具轨迹自动生成的避碰方法。五轴联动加工提供了高效和精确加工的潜力，但刀具与周围物体之间的碰撞仍然是一个严重的问题。该方法基于由两个决定刀具姿态的参数定义的二维位形空间，实现了在碰撞发生位置对避碰可能性的判断，并产生避碰方向。该方法允许在没有碰撞的情况下实际铣削具有悬伸部分的测试工件。实验结果证实了该方法的有效性。
This study deals with the method of collision avoidance in the automatic tool path generation for 5-axis control machining. The 5-axis control machining offers the potential of efficient and accurate machining, while the collision between a tool and surrounding objects is still a severe problem. The method devised in this study realizes the judgement on the possibility of collision avoidance at the position where the collision take place, and produces the direction of collision avoidance, based on the 2-dimensional configuration space defined by two parameters which determines the tool posture. This method allows a test workpiece with an overhanging part to be actually milled without collision. As a result, the validity of the method is experimentally confirmed.
