The deduction is 1.8 times the steel plate thickness and 1.6 times the aluminum plate. For plate under 2mm, K-factor is 0.432, R=plate thickness, unfold size can accurate to 0.05. Generally, when design the sheet metal parts, the min inner R=thickness/2, if less than that, the grooving (V-cutting) will be required to solve the problem. k factor for aluminum sheet metal . 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.

FYI: I am using a Sheet metal "Gauge" table for all my Carbon steel. 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. May 29, 2013 · So for a very large radius bend where the neutral axis lies right in the center of the material, the K-factor would be exactly 0.5, or half the thickness. Most CAD systems that have sheet metal design tools will allow you to input a K-factor that the software uses to calculate the unfolding to give an accurate blank, or flat pattern. 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 ...

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. 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))].

The program is used to calculate the K-factor in sheetmetal bending. K-factor is required to calculate the flat pattern. The program is very simple and user friendly and requires no previous knowledge. You just have to enter a value for the thickness of materials and bending radius, in inches or mm, and get the value of the K-factor.

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). Calculate K factor, bend allowance and Y factor for sheet metal bending. 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.

May 18, 2016 · “Rule of Thumb” k-factor table (source: Wikipedia) Bend allowance of slotted bends When slotting sheet metal at the bend axis, the material’s average density in the bend region is decreased. Jun 01, 2017 · In a series of posts we are going to review the most important sheet metal design terminology — Bend Allowance, Bend Deduction and K-Factor. In this post I will review what these terms mean and in the next post I will show you how to calculate and use them in SOLIDWORKS. In sheet metal bending ...

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. 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.

K-factor – Effectively 50%T Max / .25%T Min Where the neutral axis is situated in a bend is commonly called the “K-Factor” as it is signified as “K” in the development formulas. Since the inside compression can not exceed the outside tension, the k-factor can never exceed .50 in practical use. This 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.

• For aluminum, use a K-Factor of .4850 • For steel, use a K-Factor of .4800 • For stainless steel, use a K-Factor of .3900 These recommendations are not “exact”, but the will get you very close (usually within .020”) of a good flat layout. If you’d like to have a more complete and detailed table for K-Factors, contact k factors are proven within 0.1mm using an amada pressbrake. have also a data sheet from amada and the bend allowance is the same for each one , so that proves these figures correct 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.

Sep 28, 2015 · Sheet Metal: Understanding K-Factor. SOLIDWORKS sheet metal tools are relatively straight forward, but may not be clearly understood. In sheet metal, there is a powerful bend constant known as the K-Factor. It ultimately allows you to estimate the amount of stretch without knowing what type of material you are bending.

FYI: I am using a Sheet metal "Gauge" table for all my Carbon steel. 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.

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.
