研究了用球立铣刀进行五轴控制加工时刀具轨迹的生成方法。五轴控制加工已用于飞机零件以及复杂形状的模具和模具。然而，目前大多数用于五轴控制加工的凸轮系统在刀具碰撞、工件形状和加工方法方面功能有限。因此，在许多情况下，无法获得最佳切削齿位置（CL）数据，或者需要花费大量时间。为了解决这一问题，我们应用了一个三维构型空间（c空间），展示了所有刀具位置和姿态与刀具碰撞存在的关系。本研究设计的刀具轨迹生成方法使用户能够在不考虑刨削的情况下，生成反映自己的刀具姿态平滑变化和加工状态等加工策略的刀具轨迹数据。通过实验验证了该方法的有效性，并成功地铣削了一个叶轮，没有发生刀具碰撞。
The paper deals with the method of tool path generation for 5-axis control machining using a ball end mill. 5-axis control machining has been used for aircraft parts as well as for complicated shapes such as mold and dies. However, most of the present CAM systems for 5-axis control machining have limited functions in terms of tool collision, workpiece shapes and machining methods. For that reason, in many cases the optimal cutter location (CL) data cannot be obtained or considerable time is consumed. To solve this problem, we applied a 3-dimensional configuration space (C-Space) and showed the relationship between all tool positions and postures and the existence of tool collision. The method of tool path generation devised in the study enables users to generate CL data reflecting their own machining strategy such as smooth change in tool posture and the state of machining without considering the gouging. The validity of this method was experimentally confirmed by successfully milling an impeller without tool collision occurring.
