Material model assessment in Ti6Al4V machining simulations with FEM

Ti6Al4V alloy is a well-known difficult-to-cut material used in different industrial applications, to achieve the expected component quality, proper definition and control of machining process parameters must be accomplished. To address this problem, simulations with finite element method (FEM) seem an interesting engineering tool model optimize processes. Nevertheless, capability capturing behaviour observed real processes associated that describe workpiece flow stress. This contribution aimed study performance built-in AdvantEdge-2D™ laws applied orthogonal cutting under dry conditions. The numerical models were created three levels speed, constant feed rate depth-of-cut, variable rake angle (of 20° −6°/0°), but also using four constitutive laws, namely, one suggested AdvantEdge™ library, Johnson-Cook (JC) model, Power law (PL) PL coupled ductile damage model. Experimental results assess models’ accuracy predicting forces metal chips. Satisfactory regarding prediction achieved all yet when criterion was (PLD AE standard law), able chip morphology (serrated chips).
