The Effect of Cutting Parameters on Surface Integrity in Hard Turning

Manufacturers around the world constantly strive for lower cost solutions in order to maintain their competitiveness on machined components and manufactured goods. Globally, part quality has been found to be at acceptable levels and it continues to improve, while the pressure for part piece cost is enormous and is constantly being influenced downward by competition and buyer strategies. In machining processes, it is necessary to attain the desired surface quality in order to produce parts providing the required functioning. The surface quality is influenced by various cutting parameters (cutting speed, feed, depth of cut) and sometimes some other parameters. The objective of this paper is to review the effect of cutting parameters on surface integrity (surface roughness and residual stress) in hard turning.
