Simulation and Analysis on Micro Milling of AISI 1045

Abstract

Micro milling is a hot research field of advanced manufacturing technology at present. In this paper, a kind of micro milling model which can describe the deformation of high temperature, high strain, high strain rate of material behavior and reflect the size effect is established based on the characteristics of micro milling. And the finite element method is used to simulate the micro milling process. The change of flow stress and temperature and the formation of chip are analyzed for micro milling the workpiece material AISI 1045. At last, the micro milling force is predicted.
