Abstract

Turning has merged as a visible alternative to finish machining of hardened steels. It is known the surface finish and residual stresses can affect the resistance of components to failure when subjected to high cycle fatigue loads. This paper presents an experimental study of the influence of turning parameters on surfaces roughness and residual stresses. The results of variations in three process parameters were measured and analyzed. The influence of cutting speed on tool wear is considerable. A CBN tool is used as the cutting tool. The results show that both surface finish and residual stress are influenced by the cutting speed, feed rate and the nose radius.
