Abstract :Machining is one of the primary methods used to produce precision machine parts. Machining operations are influenced by many parameters. The most important of these parameters are feed and depth of cut. In addition, as a function of these parameters, many technical characteristics, particularly surface roughness, of the parts produced by machining change. For this reason, it is very important to monitor the machining parameters of the workpieces to be machined and to change them if necessary. Workpieces from many different groups of materials can be machined, but it is more important to monitor and control the machining parameters in stainless steels, which are classified difficult-to-machine materials. In this study, the optimum machining conditions were investigated to obtain the lowest surface roughness values on stainless steel materials (AISI 4462). Two different depths of cut (0.8 mm -1 mm) and three different feeds (0.1 mm/rev - 0.15 mm/rev and 0.20 mm/rev) were used. In addition, for a detailed analysis of the effect of the depth of cut parameter on surface roughness, cutting experiments were performed using three different depths of cut under the best experimental conditions. It was found that the depth of cut, and feed values have a direct effect on the surface roughness. However, it is understood that the feed is highly foremost on the surface roughness and changes the experimental results up to three times.
