Investigation of the effect of the burnishing applied to the Al2024 alloy on the surface roughness

Abstract

Surface roughness is a very important factor in determining the quality of the product to be obtained, as it affects the production cost and performance of mechanical parts. Surface quality is primarily considered as a design parameter to determine functional properties such as corrosion resistance and fatigue strength of the part. Therefore, this study aims to improve the surface roughness of Al 2024 material, which is generally used in aerospace and defense industries. Ball burnishing unit is designed to reduce the surface roughness after the machining of the manufacturing parts and to save both time and cost. The effects of force, feed rate and number of passes on the surface roughness were investigated as finishing process parameters. As a result of the experiment, it was observed that the roughness value decreased with the increase of the force and the number of passes, and the roughness value increased with the increase of the feed rate.
