Creo Sheet Metal K Factor

Calculate k factor bend allowance and y factor for sheet metal bending.

Creo sheet metal k factor.

In this article we will discuss sheetmetal bend deduction bend allowance k factor y factor and sheet metal flat pattern calculations. K factor is an import. This video to describe setting of k factor in creo and how to change developed length of sheet metal parts. The k factor in sheet metal working is the ratio of the neutral axis to the material thickness.

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 line where the transition from compression to stretching occurs is called the neutral axis. The k factor is defined as the ratio between the material thickness t and the neutral fibre axis t i e. These parameters can also be set using the bend allowance area of the sheetmetal preferences dialog box.

Our design engineers typically use a factor of 0 4 for our air formed press brake parts. The k factor is the ratio of the neutral axis location t to the material thickness mt. With a y factor of 69115 k factor of 44 the flat pattern was 7 1312 long. Creo sheet metal tutorial.

Reference pages explaining k factor and y factor. Using a variety of y and k factor bend allowance calculations designers can create flat patterns of the designs. Smt part bend allowance factor sets the value of y factor or k factor. 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.

When you bend sheet metal the neutral axis shifts toward the inside surface of the bend. Creating feature specific bend allowance using the bend allowance tab of sheet metal tools when available. K factor in sheet metal bending is a constant used to calculate sheet metal flat length or flat pattern. 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 location of the neutral axis varies and is based on the material s physical properties and its thickness. With a y factor of 5 creo default the flat pattern ws 7 0354 long. The result is parametric fully associative solid models of sheet metal parts and assemblies. Mathematically k factor value is equal to the ratio of position of neutral axis and sheet thickness.

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