Temperature modeling of micro milling process

Abstract

Prediction of the workpiece and tool temperature fields in micro milling of Titanium is important, since it affects the tool wear, has influence on the residual stresses and the 3D distortions of micro parts. An investigation on the temperature of micro milling is performed by considering mechanics and thermal analysis of the process. Considering shearing and frictional heat generations in the primary and secondary zones, temperature fields on the workpiece and on the tool are predicted by Finite Element Analysis. Theoretical simulation and experimental results are presented and discussed.
