流体喷射抛光是一种通用的工艺，用于小而复杂的光学和假肢表面的超精细抛光。该工艺的优点包括高度可控的亚毫米抛光足迹和没有工具磨损，但主要缺点是材料去除率非常低。为了解决这一问题，开发了一种新型系统，在该系统中，超声空化引起喷嘴出口上游直接产生微泡。实验数据表明，这些微气泡将去除率提高了380%，而不会导致表面光洁度的下降。本文报道了这种新型抛光系统的建模、实现和测试。(C) 2017年Elsevier Ltd代表CIRP出版。
Fluid jet polishing is a versatile process used for super-fine finishing of small and complex optical and prosthetic surfaces. Advantages of this process include highly controllable sub-millimetre polishing footprints and absence of tool wear, though the main drawback is very low material removal rate. To address this issue, a novel system was developed in which ultrasonic cavitation causes micro-bubble generation directly upstream of the nozzle outlet. Experimental data shows that these micro-bubbles boost removal rate by up-to 380%, without causing any degradation of the surface finish. This paper reports on the modelling, implementation, and testing of this new polishing system. (C) 2017 Published by Elsevier Ltd on behalf of CIRP.
