Inside Radius vs. V-Die Opening: Understanding the Relationship in Air Bending
In sheet metal fabrication, achieving accurate and consistent bend angles requires more than selecting the correct press brake and punch. One of the most important factors influencing bending results is the relationship between the inside bend radius and the V-die opening.
