摘要: Flow forming is an effective process for the manufacturing of thin-walled seamless tubes. It has been found that a number parameters affect quality and dimensional precision flow-formed In this study, required flow tools are manufactured. The out-of-roundness annealed AISI 321 steel tubular pre-form investigated various levels experimentally. Taguchi’s method employed to design experiments (DOE). considered feed rate, depth cut roller attack angle. effects contributions weight interaction these on out roundness as response function analysed. most important parameter affecting roundness. decreases with increase in it increases rate
