Abstract

Cold drawing is widely used manufacturing process for production of seamless tubes. Spring back is one the defect occurring in cold drawing process. A cold drawn tube will try to return to its original configurationupon removal of load. The phenomenon incurs due to an elastic recovery. This work is systematic investigations of optimized parameters to minimize springback viz., reduction ratio, die semi angle, land width and drawing speed through Design of Experimentsand microstructural investigations using X-Ray Diffraction, Scan Electron Microscopy and Metallurgical Microscope. The results of this study indicates that 10-15 % reduction ratio, 15 degree die semi angle,10 mm land width and 8 m/min drawing speed gives least springback for ST 52 tube material and AISI D3 die-plug material. This study has improved springback value significantly through series of experimentation and reduced the rejection by 3 % in precision tubes saving substantial amount of the cold drawing manufacturing industry.
