  • Modeling of liquid nitrogen thermal influence of Inconel 718 [Elektronski vir]
    Hriberšek, Matija, strojnik ; Pušavec, Franci ; Kopač, Janez, 1949-
    For predicting surface integrity after cryogenic machining, it is necessary to know liquified nitrogen properties when it us delivered to different locations on the cutting tool and/or workpiece. One ... of the key properties of liquified nitrogen that is still not known is its surface heat transfer coefficient, which defines the depth of the thermal affected layer of workpiece material and indirectly influence the characteristics of the machined surface integrity (residual stresses, hardness, etc.). In order to define the surface heat transfer coefficent, the numerical simulation has been designed and validated with performed temperature measuring experiments on Inconel 718, as workpiece material. For cutting force predicition, during cryogenic machining (orthogonal turning), the experimets have been conducted and teoretically also correlated with the FEM results of cryogenic machining model.
