Experimental Investigation and Optimization of Minimum Quantity Lubrication for Machining of AA6061-T6

This study presents flank wear optimization with minimum quantity lubricant (MQL) for the end milling for the machining of aluminum alloy 6061-T6. Process parameters including the cutting speed, depth of cut, feed rate and MQL flow rate are selected for study to develop an optimization model for fl...
