Abstract

This research paper investigates the effect of roller burnishing parameters on the surface hardness of 20MnCr5 steel, utilizing the Taguchi method for optimization. The study encompasses a comprehensive analysis of various burnishing parameters, including burnishing speed, feed rate, depth of penetration, and the number of passes, while maintaining constant conditions of the burnishing tool and lubrication. An L18 orthogonal array was employed to efficiently design experiments that reveal the impact of each parameter on surface hardness, measured in HRB. Through statistical analysis, particularly ANOVA, it was determined that burnishing speed, condition, and number of passes significantly influence surface hardness, while feed rate and depth of penetration have a lesser effect. The optimal parameters identified for achieving maximum surface hardness were the second level of burnishing speed, condition, and feed, combined with the maximum number of passes. This research contributes valuable insights into the optimization of roller burnishing processes, highlighting its potential for enhancing the mechanical properties of metallic components in industrial applications.
