Effect of microstructure on the surface finish during machining of V-microalloyed steel: Comparison between ferrite–bainite–martensite and ferrite–pearlite microstructures

TL;DR: In this paper, the influence of process parameters such as cutting speed, feed and depth of cut on surface roughness on both materials was compared and the results showed that the multiphase microalloyed steel exhibited high surface finish than air-cooled steel.
Abstract: Multiphase ferrite–bainite–martensite microalloyed steel produced through a two-step cooling followed by annealing route and a ferrite–pearlite steel obtained through air-cooling after forging were subjected to turning operation. The influence of process parameters such as cutting speed, feed and depth of cut on surface roughness on both materials was compared. The results show that the multiphase microalloyed steel exhibited high surface finish than air-cooled steel. The analysis of variance shows that the contribution of cutting speed and depth of cut on surface roughness are insignificant for both ferrite–bainite–martensite and ferrite–pearlite microstructures.

TL;DR: In this paper, results of an investigation into the tool-chip contact interface using uncoated tungsten-based cemented carbide tools in dry high-speed turning of AISI 1045 steel are presented.
Abstract: Friction conditions at the tool-chip interface are one of the most important inputs for modelling and simulation of the machining process. However, the nature of the tool-chip contact is often assumed in developing finite element models, thereby seriously affecting their reliability. In this paper, results of an investigation into the tool-chip contact interface using uncoated tungsten-based cemented carbide tools in dry high-speed turning of AISI 1045 steel are presented. The tests were conducted at cutting speeds ranging between 198 and 879m/min with a feed rate of 0.1mm/rev and a constant depth of cut of 2.5 mm. The effects of cutting speed on tool rake face contact length, contact area, friction, element mapping, and surface roughness are studied and discussed. It is shown that the quantitative methods, used here to characterize the tool-chip contact region, can provide valuable data for accurate and reliable modelling of the metal machining process over a wide range of cutting speeds.
