This study attempts to develop a micro-milling force model under cutting conditions considering tool flank wear effect during micro-milling of nickel-based superalloy with coated carbide micro-milling tools based on our three-dimensional dynamic cutting force prediction model established earlier. The tool wear condition in micro-milling nickel-based superalloy was obtained by finite element method. A 3D thermal-mechanical coupled simulation model for micro-milling nickel-based superalloy was developed to obtain the tool wear conditions and the distribution of stress. For the given tool geometries and machining conditions, the cutting forces considering tool flank wear effect could be determined conveniently. In addition, experiments of micro-milling nickel-based superalloy were conducted to estimate the validity of the modified model. The results showed that the proposed modified force analytical model could predict micro-milling cutting forces more accurately.
