Abstract

Abstract: Considering the wide application of dry belt fining and the importance of residual stress for bearing parts, this paper has characterized the residual stresses distribution along the depth generated by dry belt finishing after hard turning on hard materials AISI52100. The influences of applied force and finishing duration on residual stresses were experimentally investigated. The results were then theoretically discussed and further analyzed through 2D multi-scratching finite element model. Experimental measurements showed dry belt finishing produced considerable compressive residual stresses in the external layer. The insignificant effect of applied force on residual stress was caused by an essential reduction of sharing individual force on every useful local grit. Although increasing scratching numbers could intend the amplitude of residual stresses slightly as well as the influenced field depth range, the material removal process on the superficial layer would partly reset them, resulting in an ignorable effect of finishing duration. Besides, an improved measuring method with sufficient penetration depth resolution of both X-ray and electrochemical removal is expected to characterize residual stresses distribution of belt finishing more appropriately.
