Effects of cooling supply strategies and cutting conditions on tool life in end milling titanium alloy

Abstract

Titanium machining poses a great challenge to cutting tools, and yields serious negative influence on tool life. Thus, cooling supply strategies are widely used in its machining process. On account of this, the tool wear performance from dry cutting, flood cooling and minimum quantity lubrication (MQL) techniques is investigated. This study focuses on cutting tool life under the varied cutting conditions and cooling supply strategies so as to establish effective titanium cutting. Experimental results proved that compared with dry cutting and flood cooling. MQL aided machining can remarkably and reliably improve tool life in titanium machining.
