The preliminary experimentation and available information indicate that careful setting of burnishing parameters is essential to have better surface finish and surface hardness. This paper presents empirical model of surface roughness (Ra) and hardness (Hw) for low plasticity burnishing (LPB®) process using dimensional analysis. The methodology of selecting the right set of dimensionless group among the different possible combinations, selecting different respective variable groups has been discussed. The constant of (Ra) and Hw in specialized form of the equation are evaluated from experimental results. The developed empirical models show close agreement with the observed values with correlation coefficient within confidence level. LPB® is a registered trademark of Lambda Technologies group.
