The K Factor For Bending Sheet Metal

Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape.

The k factor for bending sheet metal.

The k factor is empirically determined for. You could say it s the roux of the precision bending gumbo. When you bend sheet metal the neutral axis shifts toward the inside surface of the bend. I had a question on k factors for our 3 d modeling software.

K factor plays a key role in understanding the limits a material can handle during sheet metal bending. K factor in sheet metal bending is a constant used to calculate sheet metal flat length or flat pattern. Sheet metal bending methods design tips k factor bending is one of the most common sheet metal fabrication operations. Mathematically k factor value is equal to the ratio of position of neutral axis and sheet thickness.

It seems the most basic value while calculating bending allowance ba and bending deductions bd. In this article we will discuss sheetmetal bend deduction bend allowance k factor y factor and sheet metal flat pattern calculations. Use the known k factor and the known inner bending radius to calculate the bending radius of the neutral line. Get the roux right and you re on your way to making a tasty meal.

Our design engineers typically use a factor of 0 4 for our air formed press brake parts. If you gain the correct k factor your precise bending will be ensured. The k factor is the ratio of the neutral axis location t to the material thickness mt. Of all the mathematical constants in precision sheet metal fabrication the k factor stands out.

K factor is the most significant among the math constants in sheet metal fabs. The factor offsets the neutral line piece in the bend region from its center path until it has the length of the corresponding region of the flat pattern. Calculate k factor bend allowance and y factor for sheet metal bending the k factor is the most important and elusive variable of bending because it varies both as a function of the material and according to parameters such as angle and tooling.
