This paper presents the results of experimental studies carried out to conduct a comprehensive investigation on the influence of ultrasonic vibration of workpiece on the characteristics of Electrical Discharge Machining (EDM) process of FW4 Welding Metal in comparison with the conventional EDM process. The studied process characteristics included the material removal rate (MRR), tool wear ratio (TWR), and surface roughness (Ra and Rmax) of the workpiece after the EDM and ultrasonic assisted EDM (US-EDM) processes. The experiments performed under the designed full factorial procedure and the considered EDM input parameters included pulse on-time and pulse current. The experimental results show that in short pulse on-times, material removal rate in the US-EDM process is approximately quadruple than that of the EDM process. On the contrary, in the long pulse on-times, ultrasonic vibration of work??piece leads to the reduction in the MRR. On the other hand, in short pulse on-times, the TWR in the US-EDM process is lower than that of in the EDM process, and this condition reverses with increase in the pulse on-time. Furthermore, the surface roughness of the workpiece machined by EDM process is slightly lower than that of applied to the US-EDM process.

在不少场合下,航天用工程材料处在极端条件下工作,这就对材料提出许多特殊的要求,虽然国内外有一定的研究积累,但对更精确的模型和符合特定材料的损伤的状态方程,有待深一步研究。如高级弹头再入时气动加热和粒子云侵蚀以及两者耦合效应引起弹头防护材料增大后退量的问题;空中垃圾和微流星的高速碰撞对航天器的威胁;特别是核爆和激光武器对材料的损伤和破坏,实质上是辐射引起的热击波层裂破坏,这些都属于超高速碰撞对材料的响应问题。天线罩材料、吸波材料、红外隐身材料、电磁屏蔽材料都是具有不同波长电磁波的电磁功能材料,它们对固体介质的穿透、吸收、反射等会产生响应,不同的电磁功能材料,其宏观性能的物理参量不同,但有几个参量是通用的,如介电常数、磁导率和损耗角正切,搞清这些参量与材料微观结构的关系,可以为材料设计和材料创新提供科学依据。
