SendCutSend bends thousands of parts every day, so we know a little something about bending and forming. To ensure your parts meet our guidelines and are bent precisely as you intend, there are essential bend calculations and equations that can help accurately calculate bend allowance and bend deduction. In this video, we discuss those calculations and equations to assure your file is ready to go when you upload it to SendCutSend for cutting and bending.

Building on the key terms from Lesson 1, we’ll explore how they factor into bend calculations while introducing new concepts. Bend allowance refers to the mid-line distance of a bent and stretched area, while bend deduction determines how much material needs to be removed to achieve the correct flange lengths after bending. We’ll also look at how changes in bend angle and bend radius impact these calculations and why understanding these relationships is critical for precise part design.
