Simulation Analysis and Experimental Validation of Micro-feature Grinding for High-elastic Alloy Steel 3J33 with Considering Hardness

Abstract

Abstract: Aiming at the problems of machining difficulty and experimental complexity of high-elastic alloy steel 3J33, a simulation study was carried out in the machining processes. Based on the elastic-plastic mechanics, grinding mechanism and finite element analysis, considering hardness for single grain grinding thin rib a residual stress simulation model was established by professional metal cutting simulation software AdvantEdge. Simulation analyses and comparisons of the residual stresses of different hardnesses for thin ribs were conducted when grinding and verified through the experiments. Finally, the reliability of the optimized simulation model was verified.

Key words: flexible joint, hardness, residual stress, micro-feature
