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 k factor is the ratio of the neutral axis location t to the material thickness mt.
Mathematically k factor value is equal to the ratio of position of neutral axis and sheet 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.
With a y factor of 69115 k factor of 44 the flat pattern was 7 1312 long.
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.
In this article we will discuss sheetmetal bend deduction bend allowance k factor y factor and sheet metal flat pattern calculations.
Smt part bend allowance factor sets the value of y factor or k factor.
Creo sheet metal tutorial.
Using a variety of y and k factor bend allowance calculations designers can create flat patterns of the designs.
Our design engineers typically use a factor of 0 4 for our air formed press brake parts.
Calculate k factor bend allowance and y factor for sheet metal bending.
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.
K factor in sheet metal bending is a constant used to calculate sheet metal flat length or flat pattern.
Reference pages explaining k factor and y factor.
The k factor is defined as the ratio between the material thickness t and the neutral fibre axis t i e.
The line where the transition from compression to stretching occurs is called the neutral axis.
These parameters can also be set using the bend allowance area of the sheetmetal preferences dialog box.
The k factor in sheet metal working is the ratio of the neutral axis to the material thickness.
The part of the material that bends without being compressed nor elongated.
K factor is an import.
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 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.
