Journal ArticleDOI
A physically based constitutive model for predicting the surface integrity in machining of Waspaloy
Stano Imbrogno,Sergio Rinaldi,Domenico Umbrello,Luigino Filice,Rodolfo Franchi,Antonio Del Prete +5 more
TL;DR: In this article, the deformation mechanisms that occurred in chip formation and on the machined surface were investigated in order to build-up a physically based constitutive model, and the developed material model was implemented via sub-routine in a commercial Finite Element software.
Journal ArticleDOI
Roller burnishing of Ti6Al4V under different cooling/lubrication conditions and tool design: effects on surface integrity
TL;DR: In this paper, a deep experimental study on surface modifications induced by roller burnishing process of Ti6Al4V titanium alloy has been performed based on a design of experiments at varying lubrication/cooling strategies, roller geometry, coating, and burnishing speed.
Journal ArticleDOI
Finite element modeling of microstructural changes in Waspaloy dry machining
TL;DR: In this paper, a user subroutine was implemented in FE code to simulate the dynamic recrystallization and consequently grain refinement and hardness variation on the machined surface and below it.
Journal ArticleDOI
Modelling the effects of twinning and dislocation induced strengthening in orthogonal micro and macro cutting of commercially pure titanium
TL;DR: In this article, a physics-based finite element (FE) model was presented to explore the microstructural phenomena occurring during severe plastic deformation processes, taking into account the influence of deformation-induced twinning, dislocation accumulation, and grain size evolution.
Journal ArticleDOI
2D FE Prediction of Surface Alteration of Inconel 718 under Machining Condition
Krunal Rana,Sergio Rinaldi,Stano Imbrogno,Giovanna Rotella,Domenico Umbrello,Rachid M. Saoubi,Sabino Ayvar-Soberanis +6 more
TL;DR: In this paper, the authors investigated the effects of extreme cutting parameters on the surface and subsurface alterations such as grain size and hardness changes by developing a finite element (FE) numerical model.
