Many designers reference a chart like this or use test pieces to calculate the K-Factor for specific projects. SOLIDWORKS defaults to calculating the flat pattern using the K-Factor. This is a decently conservative approach .
K-factor is a crucial parameter used in sheet metal bending calculations. It represents the location of the neutral axis in a bent sheet metal part. The neutral axis is the theoretical line within the material thickness where neither compression nor tension occurs during bending. Use one of the listed K-Factor calculators and measurement of a sample bent part: K Factors Autodesk Inventor; Inventor K Factor Calculator; Manually calculate the K-Factor using the measure of sample sheet metal parts that were bent using the following formula: The K-factor is determined by the physical properties of the material, bending method, bending angle, and other factors. Material Properties: it typically ranges between 0.30 and 0.50.In general, the K-factor of soft copper or soft copper materials is 0.35, the K-factor of materials such as semi-hard copper or brass, mild steel and aluminium is 0.41, and the K . The K-factor in sheet metal is a ratio to determine where the neutral axis (where the material is neither in compression nor tension) lies within the thickness of the bent material. It is important to predict the bending allowance, which is the amount of material needed to achieve a desired bend. This is important for designers and fabricators .

K-factor – Effectively 50%T Max / .25%T Min Where the neutral axis is situated in a bend is commonly called the “K-Factor” as it is signified as “K” in the development formulas. Since the inside compression can not exceed the outside tension, the k-factor can never exceed .50 in practical use. This Bend relief notch 4. A consistent bend orientation is important for ease of fabrication.. 5. The K-factor of your bending design should be chosen from a K-factor chart based on the material type, bend angle, and operation. It typically ranges from 0.25 to 0.50. 6. If your design has offset bends ( Z-shaped), Maintain flange length (on Both Sides)= 3 x thickness(t)If the value of sheet metal K factor and bending flange length is known. Sheet Metal flat length can be calculated in the following three steps. Step-1: Calculate the value bend allowance for the required sheet metal bend by using the below formula. Bend Allowance (BA) = (Π/180) × . The k-factor is fundamental in the press-bending sector and is closely linked to the concept of spring back. It is also known as bend allowance and serves to calculate the sheet metal layout. Knowing the k-factor formula is essential in order to bend any kind of sheet metal correctly; in fact, it varies according to the type of material to be deformed. .
Sheet Metal K-Factor Chart. A K-Factor Chart provides reference values, usually between 0 and 0.5, for common materials like steel, aluminum, and stainless steel. It’s a starting point for general fabrication, indicating typical deformation degrees for various thicknesses and materials.
