Hard steels are extensively used in gamut of uses such as aerospace, vehicles and die and mold industries. These materials have high strength and hard- ness which leads to a difficulty in their manufacturing. In addition to the required high forces during the production by machining and the resulting tool wear, it needs machine tools with high stiffness. Such characteristics will result in a production cost that can reach half of the product cost and high investments in addition to the need for subsequent finishing operations. Laser assisted machining (LAM) represents a new step towards a promising technique for machining new materials that are difficult to machine. It offers local heating of the work before conventional cutting takes place. Tool steel is an important example of these materials. In this work laser assisted turning of tool steel DIN 1.2379 is investigated. Nd:YAG pulsed laser head of 350 W power is used to assist conventional turning operation. For process evaluation, a comparison of conventional and LAM was introduced considering tool life, cutting forces. The influences of different cutting speeds, depth of cuts and laser powers were discussed. The experimental results showed a considerable increase of tool life, a reduction in cutting forces, when using LAM in turning operation.
