Cryogenic CO2-assisted minimum quantity lubrication milling technology is a green processing with broad application prospects. Aiming at the problem of tool wear in cryogenic difficult-to-machine materials and influence relevant parameters on wear, this study used coated cemented carbide tools to perform experiments under conditions. The micro-morphology chip was observed, energy spectrum conta...

This study focuses on milling under sustainable cutting conditions of ST52 steel, frequently used in the manufacturing industry. steel is a good candidate as workpiece because it inexpensive and readily available. To achieve conditions, zone minimum quantity lubrication technology was during processing. The experiments three speeds (120-180-240 m min-1), feed rates (0.12-0.18-0.24 mm rev-1), co...

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...
