Numerical investigation of the effects of process parameters on forming load and failure in hot nosing process

Abstract

Abstract. Nosing process is generally used to reduce the diameter of the open end of the circular thin-walled tubes. Friction coefficient and workpiece temperature are two important process parameters that should be investigated to understand the process in detail. In addition, forming length and nosing ratio need to be considered to carry out a successful process. If these parameters are not determined correctly, workpiece damage like buckling is inevitable. The purpose of this study is to investigate the effects of the process parameters on the forming load and failure of the workpiece in the hot nosing process.
