Abstract
The surface texture of martensitic AISI 630 steel after the finishing turning is described. The tests were carried out under dry and cooling conditions. Experiments were carried out under variable cutting speeds and feeds and under a constant depth of cut. The Parameter Space Investigation (PSI) method was used that allows research with minimal experience point quantity. It was found that turning with cooling conditions reduce both Ra and Rq values and intensities of cutting speed and feed rate influence as compared out under dry conditions. The use of low feed rate values has a positive effect of the Ra and Rq parameters.
Highlights
The surface texture of martensitic AISI 630 steel after the finishing turning is described
The surface quality largely determines the usable properties of the workpieces, including tribological properties, fatigue strength and corrosion resistance [7]
The research was aimed at determining the impact of cutting speed and feed on selected surface roughness indices obtained during finishing of AISI 630 stainless steel, dry and with cooling
Summary
Struktura geometryczna powierzchni po toczeniu wykończeniowym stali martenzytycznej AISI 630. Martensitic, chromium-nickel aging stainless steel AISI 630 (17Cr-4Ni) is characterized by high strength, hardness and ductility and excellent corrosion resistance [5]. This material has a low thermal conductivity, which reduces machinability and affects the quality of the surface [6]. Parameters such as cutting speed, feed, depth of cut or corner radius of the tool affect the quality of the surface. The research was aimed at determining the impact of cutting speed and feed on selected surface roughness indices obtained during finishing of AISI 630 stainless steel, dry and with cooling
