Analysis of the minimum chip thickness during turning of duplex stainless steel

Schultheiss, Fredrik LU ; Agmell, Mathias LU ; Bushlya, Volodymyr LU and Ståhl, Jan Eric LU (2018) In Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture 233(7). p.1733-1744
Abstract

The goal of this study has been to establish a method for quantifying the minimum chip thickness, h1min, during longitudinal turning of duplex stainless steel, and explore how the value of h1min changes with varying process parameters. Based on experimental results, it was found that the tool edge radius only has a limited influence on the size of h1min up to a certain feed level after which the chip flow direction close to the nose radius will have an increasingly pronounced effect. Experimental results show that h1min may be as large as 40% of the theoretical chip thickness when machining duplex stainless steel, results which were corroborated by an finite element method (FEM) analysis....

The goal of this study has been to establish a method for quantifying the minimum chip thickness, h1min, during longitudinal turning of duplex stainless steel, and explore how the value of h1min changes with varying process parameters. Based on experimental results, it was found that the tool edge radius only has a limited influence on the size of h1min up to a certain feed level after which the chip flow direction close to the nose radius will have an increasingly pronounced effect. Experimental results show that h1min may be as large as 40% of the theoretical chip thickness when machining duplex stainless steel, results which were corroborated by an finite element method (FEM) analysis. Thus, it can be concluded that a substantial amount of workpiece material will only be deformed onto the machined surface or will form the side flow and not removed as a chip.
