Understanding the bending process: simple factsġ) The radius obtained on a bent part affects the length to which we must cut that part (before bending).Ģ) The radius obtained on bending depends 99% on the V opening we choose to work with.īefore designing the part and surely before starting to cut the blanks, we MUST know EXACTLY what V opening we will use to bend the part on the press brake.Ī larger radius will “push” the legs of our part toward the outside, giving the impression that the blank was cut “too long”. Well, Rolleri is here to help! Read our tutorial below to learn more about the factors involved when trying to get the best results. Or maybe the parts that are designed on the computer do not meet reality once bent on the floor. Maybe you’ve received laser cut, punched, or sheared parts that seem “too long” or “too short” once bent on the press brake. Understanding the relation between V opening, radius, bending allowance, and K factor is very important to better calculate an unfolded part before cutting the flat blank from the sheet metal. Correct calculation of an unfolded part for a press brake
