| ABSTRACT: Super alloys have high strength at elevated temperatures, which make them very important to various applications. Such materials are usually difficult to machine at room temperature due to excessive tool wear and poor surface finish. Laser-assisted machining (LAM) offers the ability to those materials more efficiently and economically by providing the local heating of the work piece before conventional cutting take place. AISI D2 steel is an important example of these super alloys. The machinability of D2 steel is investigated in this work. This involved the use of crystal laser as heating source together with conventional turning operation. The experimental investigation took into account the cutting forces and tool wear. A comparison between conventional and laser assisted cutting was performed. The effects of variable cutting speed, depth of cut and laser power were investigated. The experimental results showed improvement in cutting conditions and reduction in cutting forces up to 37%. | ||||
