Because of the specific properties of any given metal there is no easy way to calculate that value perfectly hence the chart in figure 2.
Creo sheet metal k factor.
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.
The k factor in sheet metal working is the ratio of the neutral axis to the material thickness.
K factor in sheet metal bending is a constant that is used to calculate sheet metal flat length.
The part of the material that bends.
Creo sheet metal training.
Using a variety of y and k factor bend allowance calculations designers can create flat patterns of the designs.
What s new creo 5 0 creo tutorials fundamentals model based definition data management design exploration part modeling data exchange detailed drawings layout surfacing rendering assembly design advanced framework design welding design electrical design piping manufacturing mold design and casting sheetmetal.
The line where the transition from compression to stretching occurs is called the neutral axis.
The k factor is defined mathematically as t mt where t is the neutral axis location and mt is the material thickness.
The location of the neutral axis varies and.
Calculate k factor bend allowance and y factor for sheet metal bending.
The k factor is defined as the ratio between the material thickness t and the neutral fibre axis t i e.
When metal is bent the top section is going to undergo compression and the bottom section will be stretched.
Sheet metal flat length can be calculated using cad softwares.
K factor a constant determined by dividing the thickness of the sheet by the location of the neutral axis which is the part of sheet metal that does not change length.
Sheet metal k factor hi graham i could be wrong for the latest creo 1 0 but till now i have never able to directly access that smt k factor system parameter with relations.
Therefore using k factor there is no need to calculate sheet metal flat length manually.
For example if the value of k factor for given material thickness and bending machines is known.
