Sheet metal bend allowance calculator - formula & step by step calculation to find the flat pattern length when a bend is dimensioned either from the centre of radius or a tangent point of radius or the outside tangent point of the radius on an acute angle bend. BA = [A x (π/180) (r + (K x T))]. With this free online tool we quickly get the sheet metal bend deduction, and therefore the sheet metal blank initial flat length, from the finished part measurements.. You only have to insert interior angle, flange lengths, K factor, inside radius, and material thickness. Now, you may be thinking, where this k factor is used. Let me make it clear that it is a very important term used in sheet metal design. It is used to calculate Bend Allowance and Bend Deduction which are further used to calculate the flat pattern.

This metal is known for its extreme durability as well as its relatively light weight. This makes titanium sheet metal extremely useful in a number of industries. For example, Grade 2 titanium sheet is frequently used to fabricate tanks and other equipment for chemical processing plants. Mar 07, 2018 · And Now, the K-factor. In sheet metal, the K-factor is the ratio of the neutral axis to the material thickness. When a piece of metal is being formed, the inner portion of the bend compresses while the outer portion expands (see Figure 1). Bend Allowance and K Factor. If you design your bent sheet metal parts in CAD software that has a special sheet metal environment, use it. It exists for a reason. When making bends, it takes material specifications into account.

I did found an excel program to calculate my k-factors and they are really close to a few of our fabricators, but that table did not calculate Aluminum. I have searched the web and all I can find is gauges, not a general bend radius with its corresponding gauge.

A while back I talked about the importance of community with respect to CAD. I came across a community sponsored application that will aid any sheet metal designer. It is a k-factor calculator developed by the New Zealand company knac solutions. All sheet metal workers know the importance of an ... K-factor in sheet metal bending is used to calculate sheet metal blank size. This calculator uses reverse engineering approach for k-factor calculation. During sheet metal bending, the inside bend surface is compressed and the outer surface is stretched. Now, you may be thinking, where this k factor is used. Let me make it clear that it is a very important term used in sheet metal design. It is used to calculate Bend Allowance and Bend Deduction which are further used to calculate the flat pattern. K-Factor. K-Factor is a ratio that represents the location of the neutral sheet with respect to the thickness of the sheet metal part. When you select K-Factor as the bend allowance, you can specify a K-Factor bend table. The SolidWorks application also comes with a K-Factor bend table in Microsoft Excel format.

Bend Allowance and K Factor. If you design your bent sheet metal parts in CAD software that has a special sheet metal environment, use it. It exists for a reason. When making bends, it takes material specifications into account. Jun 06, 2017 · In my previous post I talked about K-Factor, Bend Allowance and Bend Deduction and what they mean in sheet metal design. Now let’s see how we can obtain these values for a specific sheet. As I mentioned in my last post you need to do some tests to calculate these values for a specific sheet. These ... 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.

Mar 09, 2018 · I am assuming the bend radii and k factor would be different for a SS since it is harder than regular sheet metal. For instance right now in solidworks for say 11 GA sheet metal I use a bend radii of 0.005 and a k factor of 0.275 and that seems to work pretty well when I put the flat views on my prints.

K-factor (Elo rating system), a constant used in Elo rating system; K-factor (marketing), the growth rate of websites, apps, or a customer base; K-factor (sheet metal), the ratio of location of the neutral line to the material thickness; The K Factor, a fictional TV show within Harry Hill's TV Burp; Bondi k-factor, the "k" in Bondi k-calculus ... Sheet thickness (in): Die edge radius (in): Punch edge radius (in): Bend length (in): Ultimate tensile strength (psi): Factor of safety: Apr 25, 2018 · We produce a lot of sheet metal work using Invento and use 0.2732 for below 3mm sheet and 0.3365 for 3mm and above, using ilogic we automatically set the k-factor depending on the thk of material so we don't forget to adjust it each time. The k-factors mentioned are to suit our own press and tools of course.

Oct 11, 2018 · Issues will arise in the workshop as what I've come up is have 2 separate K factor / Spline Factor setting. For bent plate I set them as 0.01 to create a tiny radius and for or big radius or rolled plates I set it as 0.5 to get the mean of the material thickness. This seemed to work well with all of my sheet metal parts.

k factor for 6061 aluminum . If you have any questions or good suggestions on our products and site, or if you want to know more information about our products, please write them and send to us, we will contact you within one business day. K-factor. Another method for calculating bend allowance uses the k-factor. Well, K is the neutral axis offset. The general principle of this formula goes like this: The neutral axis is in my diagram here and red. They don’t change during the bending process. K-factor. Another method for calculating bend allowance uses the k-factor. Well, K is the neutral axis offset. The general principle of this formula goes like this: The neutral axis is in my diagram here and red. They don’t change during the bending process.

K-Factor in sheet metal bending is a constant. It is used to calculate sheet metal flat length/ Flat-pattern. Mathematically k factor value is equal to the ratio of position of neutral axis and sheet thickness. In this article we will discuss sheetmetal bend deduction, bend allowance, K-factor, Y-factor and sheet metal flat pattern calculations. In my line of work, our end product is about 80% sheet metal manufactured. Working closely with our sheet metal department, we have zeroed our K-factor down to .430 for our manufacturing needs. This K-factor is used in conjunction with known inside bend radii for specific materials and material thicknesses.
