Optimization study of tungsten bar rotary forging process based on deform

Abstract A numerical simulation of tungsten bar rotary forging was conducted using Deform 3D software. The effects of hammerhead radial feed, relative rotational speed, axial feed rate of the billet, and initial billet temperature on the forging process were investigated through an orthogonal test. The optimal parameters for tungsten bar rotary forging were determined as follows: The radial feed of the hammerhead is 1.5 mm, the relative rotational speed is 880 rpm, the axial feed rate is 6.5 m/min, and the initial billet temperature is 1550°C. Subsequently, a trial production of tungsten bar forging was performed using these optimized parameters. The results demonstrated that the samples produced with the optimized conditions exhibited excellent performance.
