| Abstract: | The flaring of tube ends are typically performed using electromagnetic forming, or punch-and-die method, both of which cost time and effort. In this work, a new method of tube flaring using a metal spinning process is proposed. An experimental study was carried out to flare the end of aluminium tubes. A multifunction tool was designed based on the flaring ratio to widen the tube end. Several flared specimens were conducted at different working conditions. The effects of working conditions such as flaring ratio, axial feed rate (mm/rev), and rotating speed (rpm) on the flaring loads were investigated. An experimental analysis was carried out to illustrate the effect of the working conditions on the characteristics of the formed part. The analysis showed that these working conditions have a clear influence on wall thickness, surface hardness, and flaring loads. |
