1.序言据报导,超声波振动切削,在降低切削抗力、提高加工面光洁度方面是有效的。为了更加有效地进行此种切削,必须在切削过程中保持稳定的刀具振幅。但在设计这种刀具时,由于要考虑适当提高机械发热量,得到无负载时较大的共振振幅,因此,在切削过程中,根据负载的大小,有可能大幅度地减小振动振幅,不能发挥振动切削的效果。关于超声波加工工具在负载状态下的作用问题,已经有过一些研究,其内容为:在工件沿振动方向进给速度非常缓慢的情况下加工,同时还必须满足给定的负载条件。至于象超声
1. Preamble It has been reported that ultrasonic vibration cutting is effective in reducing cutting resistance and improving surface finish. In order to do this kind of cutting more effectively, it is necessary to maintain a stable tool amplitude during cutting. However, when designing such a tool, it is necessary to consider appropriately raising the mechanical heat to obtain a large resonance amplitude at no load. Therefore, it is possible to drastically reduce the vibration amplitude during the cutting process depending on the size of the load. Play vibration cutting effect. There have been several studies on the role of ultrasonic machining tools in loading conditions, which include machining with very slow feed rates of the workpiece in the direction of the vibration while still meeting given load conditions. As for ultrasound
