Provides instruction and practice in determining proper bend allowances in sheet metal. Also reviews the interplay of different factors that affect the amount of bend allowance needed and the methods for calculating allowance. The greater the inside bend radius is the less the stretching. Also material hardness or elasticity has a lot to do with how much it stretches. Therefore bend allowance is that dimensional adjustment required to allow for the forming of sheet metal.
Dear sirs, I am working with Daksh Electronics pvt.ltd., as a mechanical engineer, I would like to know that how to calculate the blank size for sheet metal work. Bend Adjustment Calculator for the Swagelok Hand Tube Bender Bend Adjustment Calculator for the Swagelok Hand Tube Bender How to Use 1. Slide inner scale until the tube OD and the bend radius are in the window. 2. Move down to the desired bend angle and read the adjustment (gain). Adjustment (gain) on angles
