本文描述了 ZrO2 超声波辅助加工中工艺材料相互作用（材料去除机制、表面质量、裂纹附近表面等）的基本研究。实验表明刀架系统对获得的振动幅度有显着影响。对于较大的刀具振动幅度，可以观察到不同的材料去除机制。此外，工具（和/或工件）的振动会因材料破裂而导致更多的表面凹坑（近表面裂纹）。正如文献报道的那样，振动还降低了加工力，从而可以提高生产率。本文还介绍了孔、槽和型腔等简单型腔加工策略的开发。
This paper describes a fundamental investigation of the process material interaction (material removal mechanism, surface quality, surface near cracks,..) in the ultrasonic assisted machining of ZrO2. Experiments show that the tool holder system has a significant influence on the obtained amplitude of the vibration. For larger tool vibration amplitudes different material removal mechanisms can be observed. In addition, the vibration of the tool (and/or workpiece) results in more surface craters (near surface cracks) due to material break out. As reported in literature, the vibration also lowers the process force, making it possible to increase the productivity. The paper also presents the development of machining strategies for simple cavities such as holes, slots and pockets.
