FEM analyzing effect of tool body materials on security reliability for face-milling cutter
Face milling is the most common milling operation and can be performed using a wide range of different tools.Tool life is an important indicator of the milling operation in manufacturing process.In high speed machining,there are two forms of security lapse including cutter body rupture and flying out to effect face-milling cutter life.This study investigates the influence of cutting tool body material on the distribution of stress field by utilizing finite element simulations (FEM).Two kind of cutting tool body materials including Al alloys and 40CrMo tool steels were used for simulation.The cutting tool was set to be idling under different rotation speed including 5000r/min,10000r/min,15000r/min,20000r/min and 30000r/min,respectively.Results show that for the two kinds of materials,the security cutting speed is 15000r/min to Al alloys and 20000r/min to 40CrMo tool steels respectively.Under the same cutting condition,40CrMo tool steels have higher shear stress than that of Al alloys,in hence they have higher security rotation speed.
