Reference pages explaining k factor and y factor.
Creo sheet metal k factor.
These parameters can also be set using the bend allowance area of the sheetmetal preferences dialog box.
The k factor is defined as the ratio between the material thickness t and the neutral fibre axis t i e.
Mathematically k factor value is equal to the ratio of position of neutral axis and sheet thickness.
Using a variety of y and k factor bend allowance calculations designers can create flat patterns of the designs.
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 location of the neutral axis varies and is based on the material s physical properties and its thickness.
The k factor is the ratio of the neutral axis location t to the material thickness mt.
The part of the material that bends without being compressed nor elongated.
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.
When you bend sheet metal the neutral axis shifts toward the inside surface of the bend.
With a y factor of 69115 k factor of 44 the flat pattern was 7 1312 long.
I had a question on k factors for our 3 d modeling software.
Smt part bend allowance factor sets the value of y factor or k factor.
This video to describe setting of k factor in creo and how to change developed length of sheet metal parts.
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.
