Rigid-plastic finite element method is used to analyze the warm forging of spiral bevel gear.Friction condition

workpiece temperature

die preheating temperature and forging speed are investigated.From the investigation

the load increases with the increase of the friction coefficient and decreases with increase of the die preheating temperature

the workpiece temperature and forging speed.The influence of the workpiece temperature on the load is much more than that of the die preheating temperature.The simulation result can provide the reference for die design and technology layout of spiral bevel gear warm forging process.
