Deformation behavior during partial diameter-enlarged process at high rotation speeds

This paper presents the deformation behavior of SUS304 specimens during partial diameter-enlarged process in a rotation speed region higher than the rotation speed region of conventional diameter-enlarged processing methods. The deformation behavior of the specimen diameter during the process was me...

The deformation behavior of the specimen diameter during the process was measured at various axial-compressive forces, bending angles, and rotation speeds.

Finally, the time constant of diameter-enlarged was obtained for the above parameters. By increasing the rotation speed, it is possible to shorten the processing time and perform processing at a low axial-compressive force with little temperature rise, which improves the processing efficiency. The time constant of the diameter-enlarged deformation process can be expressed as a function of the effective rotation parameter.
