The cooling condition has a significant effect in the metal cutting industry, which crucial role and lubricating workpiece-tool interface, reducing friction, removing chips from area. Almost 15-20% of overall machining cost was incurred lubrication. So, considerable can be occurred due to supply, preparation, disposal lubricants. Moreover, exposure these substances pollute environment hamper op...

Due to its excellent strength, plasticity, and fracture toughness, titanium alloy has been widely used in the aerospace field. The specificity of application environment places high demands on surface quality alloy. In this paper, we study effects different lubrication methods microscopic topography, roughness, microhardness TC21 during milling process. include dry, high-pressure air cooling, m...

Minimum Quantity Lubrication (MQL) is a cooling and lubrication variant applied, for instance, in drilling processes. In the present approach, new vibration-assisted process analyzed, which has considerable potential manufacturing of extremely hard materials. Within this process, MQL gas/liquid transport presence vibrating rotating twist drill bit borehole to be studied. Multiphase computationa...

In most grinding processes, the use of cutting fluid is required, and research has been carried out to reduce amount used due costs environmental impacts. However, such a reduction can result in thermal damage machined component because may not be sufficient lubricate cool system. One way improving properties add micro or nanoparticles solid lubricants. This paper aims evaluate performance mult...

Single-channel supply of pre-mixed liquid carbon dioxide (LCO2) and minimum quantity lubrication (MQL) represents a state-of-the-art LCO2 assisted machining. However, to fully understand optimize cooling provided by the + MQL, fundamental media flow analysis is essential, yet not researched enough. Therefore, in this paper, velocity oil droplet size were analysed supplying line at nozzle outlet...

The conventional pneumatic Minimum Quantity Lubrication (MQL), when not properly designed, may have poor atomization and insufficient wetting performance, resulting in higher oil mist concentration film formation ability the cutting zone. intervention of an external electric field can change mechanism microdroplets enhance lubrication cooling capability MQL. However, effect jet parameters on pe...

Abstract Cutting fluid plays a cooling-lubrication role in the cutting of metal materials. However, substantial usage traditional flood machining seriously pollutes environment and threatens health workers. Environmental technologies, such as dry cutting, minimum quantity lubrication (MQL), cryogenic cooling technology, have been used substitute for machining. insufficient capacity MQL with nor...
