How Die Opening Affects Sheet Metal Bending Accuracy and Tonnage
In press brake bending, the V-die opening is one of the most influential tooling dimensions. It affects the amount of force required to form the sheet, the resulting inside bend radius, material deformation, springback, and ultimately the consistency of the finished part.
