Study of High Efficiency Numerically Controlled Rough Machining Strategy for Open 3D Impeller

This paper discussed the high efficiency machining strategy and the key technology of five axis numerically controlled rough machining.The main factors that affect the machining efficiency were analyzed and the flank milling with high speed steel cutting tool and plunge milling with carbide cutting tool as well as the selection of cutting tools were briefly discribed.A principal of rough machining strategy which considering the machining features of 3D impeller and the tools’life is concluded based on large quantity of 3D impeller machining experience,which made the machining efficiency of 3D impeller improved largely.
