Performance Of Water-Based TiO2 Nanofluid During The Minimum Quantity Lubrication Machining Of Aluminium Alloy, AA6061-T6

The effects of cutting parameters on the wear mechanisms in the end milling of aluminium alloy AA6061 with minimum quantity lubrication (MQL) conditions using water-based TiO2 nanofluid were investigated. Three different cutting speeds of 5200, 5400 and 5600 rpm were used. The MQL flow rates used we...

Three different cutting speeds of 5200, 5400 and 5600 rpm were used.

The major benefit from the water-based nanofluid MQL was shown in the edge integrity i.e., edge chipping and edge fracture were seen in very few cases especially with a higher depth of cut higher.
