Abstract

Laser assisted machining represents a new step towards a promising technique for machining new materials that are difficult to machine. Conventional cutting of such materials is accompanied by excessive tool wear, high cutting forces and poor surface finish. Laser-assisted turning (LAT) offers the local heating of the workpiece before conventional cutting takes place which means improving the ability of those materials to be cut more efficiently and economically. Die steel is an important example of these materials. 
In this work laser assisted turning of Die steel DIN 1.2379 is investigated. Nd:Yag pulsed laser head of 400 W power is used to assist the conventional turning operation. For process evaluation, a comparison between conventional and laser assisted turning(LAT) was introduced considering tool life and surface roughness. The influences of variable cutting speed, depth of cut and laser power were discussed. The experimental results showed a considerable increase of tool life as well as a reduced influence on roughness height when using LATat higher speeds.
