Helical Feed Milling with MQL for Boring of Aluminum Alloy

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2008
MQL is applied to the helical feed milling hole-making process of aluminum alloy. It is difficult to drill on aluminum alloy without cutting fluid because the adhesion to the tool leads to a chip jam, the tool breakage or low accuracy.
