Neutral Axis Sheet Metal

The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend.

Neutral axis sheet metal.

In sheet metal the k factor is the ratio of the neutral axis to the material thickness. Where t is the distance. The line where the transition from compression to stretching occurs is called the neutral axis. In other words the neutral axis for this part occurs kfactor 100 of the way through the material s thickness.

Let us discuss in detail about bend allowance k factor and y factor. The neutral axis and considerations for bending plate. When the sheet is flat without any applied stress the neutral axis is in the middle of the sheet. K factor is a ratio that represents the location of the neutral axis with respect to the thickness of the sheet metal part and depends on material thickness and bend radius.

The granular bonds are stretched pulled and sometimes break forcing the grains apart as they come under tensional stresses. K factor in sheet metal bending is a constant used to calculate sheet metal flat length or flat pattern. But add a little stress and force the metal to bend and watch what happens.

When a piece of metal is being formed the inner portion of the bend compresses while the outer portion expands see figure 1. K factor k can be defined as follows. The location of the neutral axis for a specific sheet is defined by a factor called k factor. Bend allowance plays a critical role in calculating flat length of any sheet metal part.

The line where the transition from compression to stretching occurs is called the neutral axis. When metal is bent the top section is going to undergo compression and the bottom section will be stretched. The k factor in sheet metal working is the ratio of the neutral axis to the material thickness. By calculating and taking into consideration the developed lengthy a qualified metal bender roller can accurately bend plate to the desired final product.

The k factor in this case kfactor expresses that distance as a percentage of the material s thickness. When metal is bent the top section is going to undergo compression and the bottom section will be stretched. The distance between the inside surface of the part and the neutral axis is known as the neutral axis offset. The k factor in sheet metal working is the ratio of the neutral axis to the material thickness.
