Effect of Roller Axial Position and Thickness on a Twisted Angle in the Twist Rolling of Aluminum Alloy 1050 Sheet Metal

This paper proposes a new rolling method called “twist rolling” that can continuously form twisted shape by using taper rollers. The of metal sheets is widely used in industrial products such as turbine blades and propellers. Such normally formed casting or machining, but there are problems with low efficiency regarding the productivity yield ratio. Forging processes have also been proposed, they surface property. present study focuses on to efficiently shape. effect axial position rollers skew angle average specific were investigated experiments finite element analysis. relationship between thickness sheet was investigated. decreased increased. When smaller thicker, increased more. Twist various twist angles changing parameters.
