Experimental study on tool wear mechanism of TC4 titanium alloy by laser assisted cutting

Abstract

In order to improve the cutting performance of titanium alloy, and to improve the durability of cutting tool, the experiment was carried out by using laser assisted cutting technology, the tool wear form of TC4 is studied during the cutting process. the results showed that the TC4 titanium alloy was cut by hard alloy tools, tool wear form is mainly bond, diffusion wear and spalling and cutting edge. Wear mechanism is mainly bond wear and cutting edge. Under the condition of laser heating, the tool wear is less and the wear form is changed, it is helpful to improve the tool wear mechanism and improve the tool life.
