Abstract

Micro-milling is emerging as a promising fabrication process to serve the increasing needs in making miniature parts with complex three-dimensional 3D features. The prediction model of cutting force is important in a correct choice of cutting parameters, reasonable design of micro tools and accurate estimation of machining tolerances. The model should be required the capability to illustrate material behavior when the uncut chip thickness reduces to the micro scale. To answer this need, the paper proposed a cutting force model in orthogonal micro milling based on strain gradient plasticity theory. A set of slot milling experiments with a straight cutting edge were conducted to verify the proposed model. The results show a good agreement between the predicted and measured force components.
