Dependence of Shape Deviations and Surface Roughness in the Hardened Steel Turning

Abstract

The article focuses on analysis of the effects cutting parameters on the surface roughness and shape errors. Research was performed for longitudinal turning of hardened steel 145Cr with using ceramic tools of different nose radius. Shape deviations and roughness for machined surfaces ware determined. Results were analysed and conclusions were presented.

Turning Research of Additive Laser Molten Stainless Steel 316L Obtained by 3D Printing

“…Previous studies to a lesser extent have presented the machining of external surfaces of AISI 316L fabricated via SLM. The impact of machining data on the surface quality (surface roughness or surface integrity) plays an important role [28,29,30,31]. Therefore, there is a need to analyze the cutting process of metals obtained by additive technology, SLM in our case.…”

The Influence of Tool Stiffness on the Dimensional Accuracy in Titanium Alloy Milling

“…Prediction of cutting force influence on a tool deflection value and thus on dimensional accuracy in the milling process is very important [8,9]. When cutting difficult-to-cut materials (titanium, nickel alloys, stainless steels) tool rigidity plays a significant role and the suitable values of cutting data decreases the shape errors and surface roughness [10][11][12][13][14][15][16][17]. The accuracy of work-piece dimensions also depend on the proper coolant system application which aditionally can reduce the environmental load [18,19,20].…”
