An Experimental Study of Computer Controlled Shear Spinning

  • J. Frisch
  • M. Achmad

Summary

Direct computer controlled shear spinning of conical, spherical, parabolic and sinusoidal shapes was performed with 5 inch (127 mm) diameter × 0.063 inch (1.59 mm) and 0.050 inch (1.27 mm) thick blanks of 1100-0 and 6061-0 aluminum. The DNC computer program permitted both easy contouring of the mandrels and the subsequent guidance of the spinning tool dynamometer for various axisymmetric shapes. Evaluation of axial spinning forces and final product thicknesses show that computer control of spinning variables can provide better production methods.
