Thermal modeling of an orthogonal machining process
A novel procedure is disclosed, that can be incorporated into Finite Element Analysis (FEA) or other similar analysis techniques, to obtain the steady state temperature distribution in a coupled transient heat transfer analysis rapidly as well as accurately. A scale factor is used to reduce the thermal inertia per unit volume (specific heat capacity) in regions of steady state temperature distribution, thereby hastening the achievement of steady state. An application of this procedure to estimate steady state temperature distributions within cutting tools, and the estimation of cutting tool wear based on the obtained steady state temperature distributions is shown as an example.
