![]() ![]() Bend allowance is useful when you need high precision in the final dimensions of your bent part, especially when dealing with materials with known properties and consistent behavior during bending.īend Deduction: The difference between the initial length of the sheet metal and the length along the neutral axis after bending. It is typically used in calculating the flat pattern (developed length) of a sheet metal part before bending. Opt for the K Factor when you want a reliable and widely accepted method for calculating bends.īend Allowance: A measurement that accounts for the physical stretching or lengthening of the material on the outside of a bend during the bending process. Onshape allows you to input a specific K Factor or select from predefined values based on industry standards. It is a common choice for many sheet metal designers. K Factor: A dimensionless factor representing the ratio of the neutral axis length to the material thickness during bending. ![]() When designing sheet metal with the Sheet Metal model feature, locate the Material > Bend Calculation option in the dialog. In this Tech Tip, you will explore the various options available: K Factor, bend allowance, and bend deduction, with guidance on when each should be used. When it comes to Sheet Metal design in Onshape, mastering bend calculations is a key skill that can significantly impact the accuracy and manufacturability of your designs. ![]()
