摘要：Because of the differences in spindle speed and extended length of micro milling cutter, Tool life and machining surface quality vary markedly. Therefore, a geometric model of carbide end mill whose diameter is 0.2mm is built. With free meshing method, meshing density is set up reasonably, which ensure the rationality of the built finite element model. On the premise of considering the extended length of the micro milling cutter, apply linear load on the main cutting edge and front-cutting edge, carry out the deformation and stress analysis using finite element software. Applying different spindle speeds under four extended lengths, through comparing maximum stress and strain under four extended lengths, change rules are summarized and the extended lengths of the tool suited for micro-milling are achieved.
