Creo Sheet Metal K Factor

This video to describe setting of k factor in creo and how to change developed length of sheet metal parts.

Creo sheet metal k factor.

The location of the neutral axis varies and is based on the material s physical properties and its thickness. The part of the material that bends without being compressed nor elongated. Reference pages explaining k factor and y factor. K factor is an import.

Mathematically k factor value is equal to the ratio of position of neutral axis and sheet thickness. The k factor is the ratio of the neutral axis location t to the material thickness mt. 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.

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 metal is bent the top section is going to undergo compression and the bottom section will be stretched. Our design engineers typically use a factor of 0 4 for our air formed press brake parts. Using a variety of y and k factor bend allowance calculations designers can create flat patterns of the designs.

With a y factor of 5 creo default the flat pattern ws 7 0354 long. I had a question on k factors for our 3 d modeling software. These parameters can also be set using the bend allowance area of the sheetmetal preferences dialog box. In this article we will discuss sheetmetal bend deduction bend allowance k factor y factor and sheet metal flat pattern calculations.

The line where the transition from compression to stretching occurs is called the neutral axis. K factor in sheet metal bending is a constant used to calculate sheet metal flat length or flat pattern. 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.

The result is parametric fully associative solid models of sheet metal parts and assemblies. 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. Calculate k factor bend allowance and y factor for sheet metal bending. Creo sheet metal tutorial.

Creating feature specific bend allowance using the bend allowance tab of sheet metal tools when available.
