The Geometric Surface Structure of X5CrNiCuNb16-4 Stainless Steel in Wet and Dry Finish Turning Conditions

The paper presents the research results on forming the texture of the X5CrNiCuNb16-4 stainless steel surface when finish turning. Surface texture parameters were measured using the Sensofar S Neox optical profilometer. The tests were carried out in wet and dry conditions for varying cutting speeds and feeds with the constant depth of cut. The Parameter Space Investigation (PSI) method was used for planning the research, as this allows the research to be realized with a minimum number of experimental points. The results obtained were subjected to statistical analysis using Statistica 13 software. It was found that the feed influences greatly the values of surface roughness parameters, while the cutting speed affects insignificantly. For both cooling conditions, a reduction in the feed rate reduced surface roughness parameters. Lower values for surface roughness parameters were obtained when cutting with cooling in comparison with dry cutting.
