Investigation of Surface Roughness Changes in The Machining of Carbon Steel Under Sustainable Conditions

Abstract

In this study, surface roughness analysis was performed in the turning of C45 steel under Minimum Quantity Lubrication (MQL) and dry machining conditions. For this purpose, turning experiments were carried out using two different cutting speeds and feed parameters. In order to improve the machinability of C45 steel, which is one of the most used industrial materials, a graphical and statistical evaluation was made as well as the optimization approach. With three different evaluations, both the positive effect of MQL on the roughness in the turning process has been explained and different perspectives have been created for C45 steel in terms of surface roughness. The optimum values of the best surface roughness were determined and the cutting conditions was revealed as the most important parameter effecting the roughness by analysis of variance.
