摘要

Thin-web gears manufactured from 9310 steel for aerospace applications are highly susceptible to machining-induced residual stress and deformation due to their low structural stiffness. This study aims to minimize machining-induced residual stress and deformation during the turning process through numerical modeling and process parameter optimization. A multi-physics coupled finite element model of the turning process was developed to investigate the mechanisms of residual stress formation and machining deformation. A two-dimensional orthogonal turning model was established in Abaqus to predict cutting forces and residual stresses under different turning parameters, including cutting speed, forward-side feed, and back-side feed. Based on the simulation results, the optimal machining parameters were determined using orthogonal experimental design combined with Grey relational analysis. Machining deformation was measured using a coordinate measuring machine (CMM), while residual stress distribution was evaluated using the hole-drilling method. The experimental results show good agreement with the numerical predictions, confirming the accuracy and reliability of the proposed model. The proposed approach effectively reduces machining-induced residual stress and deformation, and provides technical guidance for precision turning of aerospace thin-web gears manufactured from 9310 steel.
