在电火花线切割加工中，更好地排除切缝中的碎屑对于获得稳定的加工性能是非常重要的。本研究的目的是探讨流体在切缝中的流动，以及工作流体从喷嘴喷出较佳的冲洗条件。采用计算流体力学（CFD）方法对切缝内的流场和岩屑运动进行了数值模拟，并与高速摄像机的观测结果进行了对比。讨论了喷嘴工作液流量和喷嘴间距对切缝内流场和磨屑颗粒运动的影响。(C)2009年CIRP。
In wire EDM, better exclusion of debris from the machined kerf is very important to obtain a stable machining performance. The purpose of this study is to investigate the fluid flow in the kerf and better jet flushing conditions of working fluid from the nozzles. The flow field and the debris motion in the kerf were analyzed by computational fluid dynamics (CFD) simulation, comparing with the observation by high-speed video camera. The influence of flow rate of working fluid from nozzles and the nozzle standoff distance on flow field in the kerf and debris particle motion were discussed. (C) 2009 CIRP.
