Surface morphology analysis of Duplex Stainless Steel (DSS) in Clean Production using the Power Spectral Density

The paper analyses the influence of clean manufacturing (green manufacturing) methods on the surface morphology of duplex stainless steel. The surface quality was compared using Power Spectral Density for dry and MQCL turning process. Analysis of signal power on the surface demonstrated that the wavelength is higher for dry turning than for machining using MQCL method. The amplitude of the feed ingredient is visible in the higher range of the feed, at low feed rates dominate tool vibration with the wear of the cutting tool point. In the paper the authors proved that using PSD it is possible to characterize turning regarding applied cooling methods, by qualitative and quantitative comparison of this function for inspected surfaces. Additionally amplitudes of analyzed surfaces are approximately from 1.81 μm to 2.10 μm for different feed values.
