本研究提出了一种新的加工方法来创建悬垂的尖角。悬臂曲面上的尖角很难用常规方法加工，甚至在3-5轴电火花加工中也很难加工，特别是当曲面具有不同的角度时。这是由于电极的进给方向和结构的限制，其中电极必须与目标形状对称。在本研究中，我们尝试用这种新的加工方法来加工带有悬垂曲面的尖角。六轴联动加工是将非回转刀具放在任意位置，以任意姿态对准被加工对象。在切割过程中，当刀具沿进给方向运动时，超声振动作用于刀具的刀具刃口上。在执行切割时，6个轴(X、Y、Z、A、B和C)会同时移动，具体取决于某个切削点处的刀具姿态。实验结果表明，六轴联动超声振动切割能够在悬臂面上形成尖角。
The study proposes a new machining method to create an overhanging sharp corner. Sharp corners on overhanging surfaces are difficult to machine in conventional way or even in 3 to 5-axis EDM especially if the surfaces have different angles. This is due to the limitation of the feed direction and the structure of the electrode wherein it must be symmetrical with the target shape. In present research, we try to machine the sharp corner with overhanging surfaces using the new machining method. The 6-axis control machining is applied to set a non-rotational tool at an arbitrary position with arbitrary attitude against the workpiece. During cutting, the ultrasonic vibration is applied on the cutting edge of the tool, while the tool travels along the feed direction. As the cutting is performed, the 6 axes (X, Y, Z, A, B, and C) move simultaneously, depending on the tool attitude at a certain cutting point. From the experimental results, it is shown that the 6-axis control ultrasonic vibration cutting is capable of producing a sharp corner on overhanging surfaces.
