Optimization of Honing Surface Roughness of Carburized Holes Based on GRA-RSM

The carburized holes processed by ordinary internal grinding are prone to burn, crack, and low efficiency. Honing has a superior machining efficiency cooling effect compared traditional grinding. In this paper, we innovatively apply honing carburizing hole propose an effective optimization scheme enhance the surface finish of holes. We set up experimental system explore influence law head rotation speed, axial reciprocating grain size, single depth on roughness. Based grey correlation response method, method optimize parameters establish prediction model, which R2 value 0.9887, indicating that model fits well. verify validity root mean square error 0.012 between measured calculated values. optimal roughness (Ra) is obtained verified experiments. Compared with original parameters, quality improved 25.8%. It shows optimized process based GRA-RSM improves significantly.
