| Abstract: | The mathematical models are set up which are applied to the solution of the temperature field problem of thin workpieees in high speed milling with the theory of the moving heat source. The numerical methods are presented of the partial differential equation describing the heat conduction in the plate. A conclusion is that there is a quadratic effect of High Speed Milling. The upward temperature gradient and the falling gradient accelerate with the feed rate increasing. It is important to establish theoretical basis of the High Speed Milling temperature distribution and thermal distortion manipulation, |
