Abstract

Burnishing is essentially a cold-working process used to improve properties of the machined surfaces. In present work, an attempt is made to investigate the effect of fine silicon carbide abrasive particles (in the form of a paste) in between roller burnishing tool and cylindrical components of EN24 steel. The mathematical models were developed using 2 4 full factorial design of experiments (DoE) for micro hardness in terms of four variables namely burnishing force, burnishing speed, feed and a number of passes for dry burnishing case and ‘with-paste’ (where burnishing is done using paste) burnishing case. Analysis of variance (ANOVA) is carried out to check the adequacy of the derived models. The results showed that micro hardness of the untreated EN24 steel can be improved by 11% and 18% for dry burnishing case and ‘with-paste’ burnishing case respectively compared to turned components.

Highlights

  • The functional performance of a particular engineering material depends on characteristics at the surface like surface hardness and finish

  • The above literature study reveals that both ball and roller burnishing processes are not carried out in presence abrasive paste in between tool and workpiece materials

  • A custom designed and fabricated Roller burnishing tool shown in Figure 1 is used on the conventional lathe for burnishing

Summary

Introduction

The functional performance of a particular engineering material depends on characteristics at the surface like surface hardness and finish. Responses like surface roughness, microhardness, wear resistance, ultimate tensile strength, fatigue resistance properties are found to be increased in all the works. A study on roller burnishing used RSM with central composite design in finding the effect of speed, feed, force and number of passes on surface roughens, microhardness and residual stresses in St-37 steel [12]. The above literature study reveals that both ball and roller burnishing processes are not carried out in presence abrasive paste in between tool and workpiece materials. An attempt is made to use the silicon carbide abrasive particles in form of paste applied to the workpieces before carrying out roller burnishing process and the effect of using paste is compared with dry burnishing results to conclude the effect of using abrasive materials
