Study on Simulation Processing and Engineering Experiment of Spinneret Hole Bottom Based on Material and Mechanics Properties with Different Transition Angles

Article Preview

Abstract:

The transition angle of spinneret hole bottom is usually concentrated in the three kinds of angle, 60o, 70o and 90o. Based on special processing on the transition angle of spinneret with SUS630 hole bottom and high-quality finish requirements, this paper analyzes special tool spade drill by Deform-3D FEM simulation, contrasts the trend of the axial force and torque in stable condition, and determines the optimal automation of processing parameters by engineering experiment, the angle 90o is not easier to prone the phenomenon of chipping knife, and easier processed rather ran the angle 60o and 70o, verify the results of FEA simulation.
