Creo Sheet Metal K Factor

Our design engineers typically use a factor of 0 4 for our air formed press brake parts.

Creo sheet metal k factor.

Creo sheet metal tutorial. When you bend sheet metal the neutral axis shifts toward the inside surface of the bend. K factor in sheet metal bending is a constant used to calculate sheet metal flat length or flat pattern. The location of the neutral axis varies and is based on the material s physical properties and its thickness.

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. These parameters can also be set using the bend allowance area of the sheetmetal preferences dialog box. The k factor is the ratio of the neutral axis location t to the material thickness mt. Calculate k factor bend allowance and y factor for sheet metal bending.

This video to describe setting of k factor in creo and how to change developed length of sheet metal parts. K factor is an import. The part of the material that bends without being compressed nor elongated. The k factor in sheet metal working is the ratio of the neutral axis to the material thickness.

The line where the transition from compression to stretching occurs is called the neutral axis. I had a question on k factors for our 3 d modeling software. 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 defined as the ratio between the material thickness t and the neutral fibre axis t i e.

Reference pages explaining k factor and y 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. Overview this comprehensive suite of creo sheet metal design tools helps users create features such as walls bends punches notches forms and relief features. Creating feature specific bend allowance using the bend allowance tab of sheet metal tools when available.

When metal is bent the top section is going to undergo compression and the bottom section will be stretched. Smt part bend allowance factor sets the value of y factor or k factor. The result is parametric fully associative solid models of sheet metal parts and assemblies. With a y factor of 69115 k factor of 44 the flat pattern was 7 1312 long.

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