Jet noise is a common problem in minimum quantity lubrication (MQL) technology. This should be given great attention because of its serious impacts on the physical and mental health operators. In this study, micro-grooved nozzle proposed based reduction concept biological micro-grooves. The flow field acoustic characteristics an original were investigated numerically to help better understand m...

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...

Abstract Metal cutting fluids (MCFs) under flood conditions do not meet the urgent needs of reducing carbon emission. Biolubricant-based minimum quantity lubrication (MQL) is an effective alternative to lubrication. However, pneumatic atomization MQL has poor properties, which detrimental occupational health. Therefore, electrostatic requires preliminary exploratory studies. systematic reviews ...

Micro lubrication or also known as minimum quantity lubrication (MQL) serves as an alternative to flood cooling by reducing the volume of cutting fluid used in the machining process; but not without significant health concerns. Flood cooling is primarily used to cool and lubricate the cutting tool and work piece interface during machining process. The adverse health effects caused by the use of...
