Study on Tool Performances During Machining Processes Under Mql Environment: A Review

As of now, the main requirement of industries is to produce components of the desired quality, at a high production rate with minimum expenditure. So, industries are adapting machining at high cutting speed and with high feed rates. High-speed machining increases the temperature in the cutting zone which causes faster tool wear and poor surface finish of the component. To overcome these problems,cutting fluids are used to absorb the heat from the cutting zone during machining.Thecutting fluids penetrate the chip-tool interface and quickly form a thin layer there. However, excess use of cutting fluid harmfully affects the environment and health of the worker. Also, the cost associated with cutting fluid increases the total cost of production. Minimum quantity lubrication(MQL) technique canplay a crucial function in machining where the use of cutting fluid is necessary. This study presents a review of the comparison of mechanical performances of MQL with other machining environments (Dry machining and Flood cooling) in respect of the tool performances in different machining operations.After review, it is reportedthat the machining environments have a critical influence on tool wear and surface characteristics. In many studies, the MQL technique has given better results in terms of reduced tool wear thanother cooling/lubrication techniques
