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...

The gas–liquid miscible backflow pumping seal (G-LMBPHS) is a non-contact mechanical that suitable for high-speed bearing chambers. However, the tribological properties and wear mechanisms of frictional pair G-LMBPHS in an oil–air environment have not yet been comprehensively studied. In this study, six pairs, consisting three hard materials (18Cr2Ni4WA, Al2O3 coating, Cr2O3 coating) two soft (...

Abstract The advancement of materials science during the last few decades has led to development many hard-to-machine materials, such as titanium, stainless steel, high-strength temperature-resistant alloys, ceramics, refractories, fibre-reinforced composites, and superalloys. Titanium is a prominent material widely used for several industrial applications. However, it poor machinability hence ...

Using cutting fluids is considered in industrial applications and academia due to their increased influence over many aspects such as machinability, sustainability manufacturing costs. This paper addresses the machinability perspective by examining indicators roughness, temperature, tool wear chip morphology during milling of mold steel. A special type steel Nimaxm which a difficult-to-cut mate...

In recent years, hard turning has emerged as a burgeoning cutting technology for producing high-quality finishing of cylindrical-shaped hardened steel variety industrial applications. Hard under dry was not accepted because the generation higher temperatures which accelerated tool wear and produced an inferior surface finish. Nowadays, minimum quantity lubrication (MQL) is widely in to reduce p...

This research studied the effect of channel roughness on micro-droplet distributions in internal minimum quantity lubrication for effective machining. Mixtures different oils and air were flown though channels with simulated roughness: as fabricated, partially threaded, fully threaded. The airborne droplets collected, analyzed, compared results by computational fluid dynamics. For low-viscous l...
