Abstract

This paper presents the results of an experimental study focused on understanding the performance of the hard turning at the micro-scale. Turning tests were conducted on 52100 steel hardened to 60-62 Rc. Cutting forces, surface roughness, and surface integrity, as measured by residual stresses and white and dark layer formation, were employed to assess the efficacy of micro hard turning. The results indicate that there exists a range of productive machining conditions that give rise to excellent surface roughness as well as highly compressive residual stresses at and below the surface, which are desireable in applications such as hard turning of miniature bearing races. The results of the testing also reveal that white and dark layer formation do not appear to be a problem when hard turning at the micro-scale.
