Evaluation of the atomization-based cutting fluid spray system in milling of titanium alloy
… that an atomization-based cutting fluid (ACF) spray system can effectively cool and lubricate the cutting zone during turning of Ti-6Al-4V, leading to significant improvement in machinability of titanium alloys. However, the efficacy of the ACF spray system is yet to be tested for other …

Prediction of tool temperature during machining of Ti-6Al-4V alloy with atomization-based cutting fluid spray system
Atomization-based cutting fluid (ACF) spray system is being sought as an alternative to cooling processes currently used for machining difficult-to-cut materials such as Ti-6Al-4V alloy. The ACF spray system generates a stream of monodispersed droplets of cutting fluid which then gets mixed in a …

A study on the fluid film of an atomization-based cutting fluid (ACF) spray system during titanium machining
… wear. The atomization–based cutting fluid (ACF) spray system has recently been demonstrated to improve tool life during titanium machining. The penetration into the tool–chip interface by means of the thin fluid film created by the ACF spray system appears to be the mechanism by which tool life …
