Determination of convective heat transfer coefficients in turning

A Control Volume Finite Difference (CVFD) code which finds the heat transfer coefficients resulting in a calculated thermal field that matches the thermal field obtained in experiments, was developed. The code is capable of solving unsteady conduction. and convection-diffusion problems in two or three dimensions using cylindrical coordinates. / The complex problem of the workpiece cooling, was decomposed into smaller sub-problems corresponding to the different cooling zones. For each sub-problem an inverse-problem approach was applied using data from cooling experiments as a reference. / As the result, the heat transfer coefficients were determined for a workpiece cooling in air, including the effect of the chuck, and by impinging coolant jet. The latter is defined by a distribution function. / The thermal field calculated using the heat transfer coefficients determined in this research was found to be in reasonable agreement with the thermal field obtained from experiments conducted during cutting.
