5. Continue the bend until the zero on the roller support Springback reaches the desired angle on the dial. All tubing will exhibit springback after a bend has been completed. The amount of springback depends on the bend angle, tubing material, tubing wall thickness and radius. -
Page 9: Bending On The Same Plane And Direction
Bending on the Same Plane Adjustment (Gain) Calculations and Direction Adjustment (gain) is another available method to get the desired bend. Make sure the bend is made in the right direction when making multiple bends on a single piece of tube.
