Notes:
This study investigated the model and simulation of dynamic cutting forces for highspeed end mills, performed frequency spectrum analysis of dynamic cutting forces, and propoundedthe model and failure criterion of high speed end mills with indexable inserts. According to resultsof modal analysis and stress field analysis, the safety prediction and experiment of high speed endmills for machining aluminum alloy were done. Results indicate that more teeth of cutter andgreater cutting contact angle make the energy more dispersible, higher cutting speed and greaterrake of cutter can depress dynamic cutting forces. The rigidity failure rotational speed is higher thestrength failure rotational speed, the connection strength between cutter body and screw bolt affectsdirectly the safety of cutter. The model of high speed end mills based on spectrum simulation fordynamic cutting forces, and the safety prediction based on finite element analysis should be appliedto the development of high speed end mills as an effective means
