Creo Sheet Metal K Factor

Mathematically k factor value is equal to the ratio of position of neutral axis and sheet thickness.

Creo sheet metal k factor. These parameters can also be set using the bend allowance area of the sheetmetal preferences dialog box. With a y factor of 5 creo default the flat pattern ws 7 0354 long. Creo sheet metal tutorial. 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.

Smt part bend allowance factor sets the value of y factor or k factor. The k factor is defined as the ratio between the material thickness t and the neutral fibre axis t i e. The k factor in sheet metal working is the ratio of the neutral axis to the material thickness. The k factor is the ratio of the neutral axis location t to the material thickness mt.

Reference pages explaining k factor and y factor. The location of the neutral axis varies and is based on the material s physical properties and its thickness. The line where the transition from compression to stretching occurs is called the neutral axis. This video to describe setting of k factor in creo and how to change developed length of sheet metal parts.

Our design engineers typically use a factor of 0 4 for our air formed press brake parts. In this article we will discuss sheetmetal bend deduction bend allowance k factor y factor and sheet metal flat pattern calculations. 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. Calculate k factor bend allowance and y factor for sheet metal bending.

Overview this comprehensive suite of creo sheet metal design tools helps users create features such as walls bends punches notches forms and relief features. The result is parametric fully associative solid models of sheet metal parts and assemblies. Creating feature specific bend allowance using the bend allowance tab of sheet metal tools when available. 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.

The part of the material that bends without being compressed nor elongated. K factor is an import. When you bend sheet metal the neutral axis shifts toward the inside surface of the bend. When metal is bent the top section is going to undergo compression and the bottom section will be stretched.

I had a question on k factors for our 3 d modeling software.
