Abstract
In this work, 15-5 PH stainless steel which is one of the hard to machine materials has been selected to investigate the machinability characteristics under dry cutting condition with the aid of laser surface treatment process. Turning experiments were performed on the laser surface treated 15-5 PH samples with TiAlN coated tungsten carbide inserts. Machinability of both as received and laser surface treated samples were evaluated in terms of microstructure, microhardness, tangential cutting force, surface roughness, chip morphology and tool wear. Experimental consequences revealed that laser surface treated sample exhibits a remarkable effect on microstructure and microhardness. From the parametric analysis, it is found that machining of laser surface treated samples are beneficial in terms of reducing cutting force and are effective in prolonging tool life when compared with that of as received samples.
