Examination of the effects of burnishing apparatus on surface roughness and hardness in burnishing process

Abstract

Burnishing process is a finalization process used to improve the quality of the surface. The advantages of this process is to increase surface hardness and decrease of surface roughness on the surface work-piece on which it is applied, resistance against material fatigue and abrasion resistance. In this study, the design and manufacture of three different apparatus has been realized in order to perform burnishing process by using different parameters (burnishing force, feed rate and number of passes). The effects of these parameters on the Al-6061-T6 material have been examined depending on surface hardness and surface roughness. The test results obtained by the apparatus used in the study are compared with each other. Also the effects of parameters used during burnishing on surface roughness and surface hardness are determined. Finally, the obtained results have been assessed on artificial neural networks (ANN) by using different neuron structures and algorithms, and the obtained data are compared with the test results.
