Ultrasonic drilling for brittle/hard-to-cut material by on-machine-formed small diameter tool

提高处理难切割材料的生产率和效率以保持竞争力是盈利公司管理的重要要求。新材料或改性材料的不断引入对切削技术提出了新的挑战。特别是在零件上钻深而细的孔，尽管迄今为止工具和切削材料部门进行了大量的开发活动，但尚未得到最佳解决。振动钻孔是基于脉冲冲击的间歇加工，因为刀具与切屑分离。对振动钻的效果进行了设计。利用高速摄像机捕捉了振动模式和芯片生成过程。对台式电火花线切割加工工具的振动钻孔性能进行了验证。

Enhancement of productivity and efficiency for handling difficult-to-cut materials to maintain competitiveness is a significant demand of profitable company management. The continuous introduction of new or modified materials created a new challenge to cutting technology. To drill deep and fine holes into components, in particular, has not been optimally solved yet despite intensive development activities the tool and cutting material sectors up to now. Vibration drilling is based on intermittent machining by pulse impact, because of tool separation from the chip. The effect of vibrating drill was designed. The vibration mode and chip generation was captured by using high-speed camera. The performance of vibration drilling where tool is manufactured by desk-top WEDM is demonstrated.
