## What Is Sheet Metal Bending?

Sheet metal bending is the process of transforming flat sheet metal into a three-dimensional shape using pressure equipment and specialized molds.

The specific type of bending machine, upper and lower molds, and special molds used will vary depending on the material, thickness, length, and width of the plate, as well as the desired shape and angle.

To achieve the desired results, different bending machines with varying tonnage and pressure, molds with different heights, shapes, and v-openings, as well as molds with unique shapes, are necessary.

## FAQs

**1. What is a sheet metal bending calculator? **

A sheet metal bending calculator is a tool that enables you to rapidly determine the crucial parameters in sheet metal bending calculations.

**2. What parameters can be calculated using a sheet metal bending calculator? **

A sheet metal bending calculator can calculate parameters such as the K-factor, Y-factor, bend allowance, bend deduction, arc length, and unfolding flat size.

**3. What is the K-factor in sheet metal bending calculations? **

The K-factor is a constant that represents the location of the neutral axis in relation to the thickness of the material being bent.

**4. What is the Y-factor in sheet metal bending calculations? **

The Y-factor is a constant that represents the amount of springback that occurs during the bending process.

**5. What is bend allowance in sheet metal bending calculations? **

Bend allowance is the length of the neutral axis in a bend and represents the amount of material needed to accommodate the bend.

**6. What is bend deduction in sheet metal bending calculations? **

Bend deduction is the amount of material that needs to be removed from the flat blank to achieve the desired size of the bent part.

W. Peter schubertShane,

this calculator is great! I am not that versed in Sheet Metal and i can not find any consistent reference for how to calculate the Neutral Axis. Your calculator obviously gets it correct. would you share your method?

Thanks,
