Bend allowance The bend allowance determines the amount of material taken up to form the bend. A number methods exist - K Factor - Bend Table - Bend allowance - Bend deduction
Sample bend calculation Below demonstrates the effect of neutral axis location (k factor) on the folded component.
Minimum Bend Radius Some material bend mores easily than others. Shown below is the min bend radius for different materials
Spring back When metal forming spring back must be taken into account.
