Creo Sheet Metal K Factor

These parameters can also be set using the bend allowance area of the sheetmetal preferences dialog box.

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 is defined as the ratio between the material thickness t and the neutral fibre axis t i e. With a y factor of 69115 k factor of 44 the flat pattern was 7 1312 long. 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. In this article we will discuss sheetmetal bend deduction bend allowance k factor y factor and sheet metal flat pattern calculations. Overview this comprehensive suite of creo sheet metal design tools helps users create features such as walls bends punches notches forms and relief features. When you bend sheet metal the neutral axis shifts toward the inside surface of the bend.

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. Mathematically k factor value is equal to the ratio of position of neutral axis and sheet thickness. The line where the transition from compression to stretching occurs is called the neutral axis. Smt part bend allowance factor sets the value of y factor or k factor.

With a y factor of 5 creo default the flat pattern ws 7 0354 long. The k factor is the ratio of the neutral axis location t to the material thickness mt. 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. Calculate k factor bend allowance and y factor for sheet metal bending.

K factor in sheet metal bending is a constant used to calculate sheet metal flat length or flat pattern. Our design engineers typically use a factor of 0 4 for our air formed press brake parts. K factor is an import. Creo sheet metal tutorial.

The part of the material that bends without being compressed nor elongated. Creating feature specific bend allowance using the bend allowance tab of sheet metal tools when available. The k factor in sheet metal working is the ratio of the neutral axis to the material thickness. When metal is bent the top section is going to undergo compression and the bottom section will be stretched.

The result is parametric fully associative solid models of sheet metal parts and assemblies.
