Auto panel dies are large and complex equipments for automobile production. High-speed machining (HSM) technology can be widely used to produce auto panel dies for its great increases in material removal rate, machining accuracy, and machined surface quality, while decreases in machining cost. Technologies of high-speed machining process are very important for HSM application. The study on numerical simulation and key technologies of high-speed machining process for auto panel dies has great theore...
