Modeling of the effect of burnishing force on average surface roughness

Abstract

The better fatigue resistance for a machine part can be achieved with the less macrostructural changes and inhomogeneities. In addition, the more favourable stress condition and the smaller surface roughness are decisive in terms of service life. Our publication deals with the finite element modeling of the effect of burnishing force on the average surface roughness during burnishing process which effectively reduces roughness. The method is simulated using DEFORM-2D software, corresponding to the numerical values of burnishing parameters (force, speed, feed rate) implemented in practice as well, thereby allowing a comparative analysis in the case of low alloyed aluminium as well.
