Cold flow forming was investigated with both forming experiment and numerical analysis. Flow forming is a kind of incremental forming processes which uses a roller to form a cylindrical part with repeated turning of both roller and sheet. This process has several advantages over conventional forming methods to fabricate cylindrical parts. One of the advantages is that flow forming enables a quite high degree of near net shaping of a cylindrical part. Also, it usually increases mechanical properties such as fatigue strength due to strain hardening which occurs during the process. In the present study, optimum process parameters were tried to be sought by both using a series of experiments and numerical analysis.
