In this research, we investigated the possibility of the Dry EDM(electric discharge machining) using machining centre (MC), and we attempted a super hard alloy machining by the Dry EDM using a die sinking EDM, and the research on three dimension machining (3-D machining) were done. First of all, it describes from the investigation result of the possibility that the Dry EDM is possible to process by using a MC. As a result, it have been obtained the higher machining speed when it processes Z axially and it reaches prescribed depth, the tool electrode is sent to the following processing point at high speed compared with when the tool electrode a little cut depth was put Z axially and the it was sent X axially at high speed. And the processing by the pseudo-servo sending using the Z axis of MC which have a high-speed sending ability and a high acceleration and deceleration ability was tried. In this result, the improvement of the machining speed reached the ceiling though the effect of a pseudo-servo was admitted, because the Z axis movement speed is a limit due to the Z axis have the heavy mass. Therefore, it is necessary to process it by using the working table with a high frequency response.Here, a super heard alloy machining and the 3-D machining by Dry EDM using a traditional EDM are described. As a result, a super heard alloy machining, when the supersonic vibration was added to the tool electrode or the workpiece, the improvement of the machining speed and the tool electrode wear ratio were decreased. Moreover, 3-D machining was excellent the processing in the Dry EDM in the point of the machining speed, the tool electrode wear ratio, and the processing accuracy compared with the traditional EDM processing of the past. And we were tried to a 3-D machining by the Dry EDM using 5-axis machining. In this result, the machining speed's remarkably improving compared with the processing by 3-axis machining.

在这项研究中，我们使用加工中心（MC）调查了干燥的EDM（电气加工）的可能性，并尝试使用Die die stroning EDM通过干燥的EDM进行超硬合金加工，并完成了三维加工（3-D加工）的研究。首先，它从研究结果中描述了通过使用MC进行干燥EDM进行处理的可能性。结果，当它在轴上进行z处理并达到规定的深度时，它已获得更高的加工速度，与刀具电极相比，将工具电极发送到以下处理点，与刀具电极相比，将小切割深度放在轴向上，并以高速向轴线发送x。并且使用具有高速发送能力和高加速度和减速能力的MC的Z轴来发送伪武器的处理。在此结果中，尽管接纳了伪塞的效果，但加工速度的提高到达了天花板，因为Z轴运动速度是由于Z轴的限制，因此具有重质量。因此，有必要通过使用高频响应的工作表进行处理。在这里，描述了使用传统EDM的超级听到的合金加工和干燥的EDM加工的3D加工。结果，当将超音速振动添加到工具电极或工件中时，超级听到的合金加工会降低加工速度和工具电极磨损比的提高。此外，与过去的传统EDM处理相比，在加工速度，工具电极磨损率和处理精度下，干燥的EDM的处理非常出色。然后，我们使用5轴加工尝试了干EDM进行3D加工。在此结果中，与3轴加工处理相比，加工速度的提高了。
