# Sheet Metal Bending Calculator (Free to Use)

## Sheet Metal Bending Calculator

Our free online sheet metal bending calculator enables you to rapidly determine the crucial parameters in sheet metal bending calculations, such as the K-factor, Y-factor, bend allowance, bend deduction, arc length, and unfolding flat size.

### Instructions:

• Input material thickness and inner radius to get the data of K factor, Y factor, neutral layer.
• Then input the bend angle to get the arc length, bend allowance and bend deduction.
• And then input leg length A and B to get the flat size of the sheet.

## What is the impact of different material types on the bending factor in sheet metal bending calculations?

In sheet metal bending calculations, the impact of different material types on the bending factor primarily manifests in the following areas:

Material Type:

Different material types affect the calculation and application of the bending factor. This is due to the varying mechanical properties, heat treatment states, and reactions during the machining process of different materials, all of which can impact the shape and dimensional accuracy post-bending.

Material Thickness:

The thickness of the material is another crucial factor influencing the bending factor. Generally, thicker materials require more force to overcome their internal stress during bending, which may result in greater spring back or the need for more precise calculations to ensure the shape post-bending conforms to design requirements.

The angle and radius of bending can also impact the calculation of the bending factor. A smaller bending radius or a larger bending angle may subject the material to greater stress, thereby affecting the shape and dimensions post-bending. Therefore, when performing sheet metal bending calculations, it’s necessary to choose an appropriate bending factor based on the specific bending conditions.

Other Factors During Bending:

Besides the factors mentioned above, the type and speed of the machine tool during bending can also affect the calculation and application of the bending factor. For instance, using different machine tools or adjusting various bending parameters may impact the final shape and dimensions of the material.
