Based on the ABAQUS software

drawing process of the TC4 titanium alloy with ?0.5 mm filament was simulated. The results indicate that along the workpiece axis

the residual stress is greater in the contact area between the workpiece and the mold compression cone

while along the workpiece radial direction

distribution area of the minimum residual stress varies with the mold compression angle. As the compression rate increases

the distribution area of maximum residual stress outside the workpiece is increased. When the compression rate is greater than 50%

the workpiece is cracked. The drawing temperature is increased with increase of mold compression angle and compression ratio. In actual production

it is more suitable for the pass compression rate less than 20%

the total compression rate less than 50%

and the mold compression angle less than 25°.
