Bending Radius (R) is inside radius at which bending of the plate take place. bending radius is also important parameter too small bending radius is causes to developed crack on the plate so choosing bending radius is also needs attention normaly it is equal to thickness for small thickness plate. it generaly depends upon bending configuration.

Hi! To add to Thomas' reply, k-factor is merely a ratio defining the neutral layer. This layer is where the sheet metal unfold length is equal to the folded length. 0.44 means the layer is 44% of thickness from the inner side.

I suggest that you create a sheet metal angle with you default start part, flatten the part with the create flat pattern button, add a driven dimension 3d note to the part, and mess with the SMT_K_FACTOR value and see how it responds. Once you've got the part .008 shorter than you started with, you can change the value in your part to match. Or if you'd like, you can mess around with my included sample.

When we first set up our bend tables, we had our shop physically bend every type of material they would encounter (and would design with) which was about thirty different material types (different materials, different thicknesses, etc). We then measured the bends (we used an optical comparator to measure more accurately) so we knew then bend radius, the change in length (from the original flat), etc. From there we were able to determine the value to use for the developed length based upon a sheetmetal thickness bend radius (which very often we did not get in our shop). We put these values in our bend tables, made map keys to set up the part with the proper part parameters and bend tables based on what we wanted. The default part is initially .097 or 12 gage steel.

Note that this method is frought with peril if you do not manufacture your own parts. We now outsource all our sheetmetal. Fortunately the house that is doing the work is using all of our old equipment so the results are the same but could be very different using a different manufacturer with different tooling.

Figure 2 illustrates the sheet that is bent with the bend angle of 90 degrees. We will start by calculating the Bend Allowance. From there we can calculate the K-Factor and the Bend Deduction. After bending the sheet we need to do some measurements as shown in Figure 2.

With this bend allowance calculator, you will learn how to calculate the length of a sheet metal bend so you can optimally create metal bendings without a bend allowance chart. It works as a bend deduction calculator too!

Whenever sheet metal is bent, we will define two surfaces in relation to the bend angle \theta; the inner and outer surfaces. These surfaces are deformed in opposite ways. The inner surface is compressed while the outer surface is stretched.

We need to know where to measure this bend in the sheet metal bending calculation. Should we measure it at the inner surface? Outer? Or where? The answer is somewhere in the middle determined by the neutral axis, which is the portion in the metal that maintains its length during the bending.

Another similar concept used when working with sheet metal is the bend deduction. When measuring the length of the flanges, as seen in the picture above, we see that the sum of both will result in a length greater than the total length of the cut. The bend deduction is the amount of material we need to take from the metal sheet to achieve the correct length.

Bend allowance is important because it gives us the information to cut sheet metal to produce a bent metal piece accurately. Precise measures reduce the amount of trial and error, which in turn reduce the cost of producing bent metal pieces.

I have to assume that you are here because some aspect of your sheet metal design is causing your some heartache. Sheet metal designs can be knocked out in SOLIDWORKS in very short order. The tools available are robust and simple to use. However, depending on the precision with which you need your parts manufactured, their ease of use can make it easy to overlook a key factor in accurate parts - the flat pattern.

A press brake is a machine pressing tool for bending sheet and plate material, most commonly sheet metal. It forms predetermined bends by clamping the workpiece between a corresponding punch and die. The primary functions of a press brake involve the bending of metal sheets to create various angles and shapes, which are integral in the assembly of metal structures and products.

The tonnage required for a press brake operation is a critical factor that determines the success and quality of the bending process. Several key factors influence the amount of force needed to bend a metal workpiece effectively:

Bending is one of the most common sheet metal fabrication operations. Also known as press braking, flanging, die bending, folding and edging, this method is used to deform a material to an angular shape.

The bending force table below helps you identify the minimum flange length b (mm) and inside radii ir (mm) according to material thickness t (mm). You can also see the die width V (mm) that is needed for such specifications. Each operation needs a certain tonnage per meter. This is also shown in the table. You can see that thicker materials and smaller inside radii require more force or tonnage. The highlighted options are recommended specifications for metal bending.

Why? Because the die penetrates into the sheet, pressing a dent into the workpiece. This, along with the high forces used (about 5-8 times as much as in partial bending), guarantees high precision. The penetrating effect also ensures a very small inside radius for the bend.

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. All this information is necessary when making a flat pattern for laser cutting.

So, I talked to our experienced sales engineer who knows his bit about sheet metal bending. He lit up and decided to make the fullest of the opportunity to share his insights on sheet metal bending. Thus, he brought out a list of common mistakes and the solutions to avoid them.

If you want to strengthen the edges of your metal sheet, hemming is a great option. Still, some advice applies. It is better to leave a small radius inside the hem. Completely crushing the radius needs great power and tonnage. Also, it puts the material in danger of cracking. Leaving a radius, on the other hand, relieves this danger.

The Bend Allowance Formula takes into account the geometries of bending and the properties of your metal to determine the Bend Allowance. You will need to know your Material Thickness (MT), the Bend Angle (B

Because Bend Allowance is often confused with Bend Deduction it is important to understand which value you intend on working with. Once you understand what these values represent you can use them to accurately and quickly develop flat patterns for your sheet metal parts. Creating a chart with your standard values is a key component of speeding up this process. Many software packages like Solid Works, Inventor and Solid Edge will let you incorporate a Bend Allowance Chart into its calculations when developing flat patterns.

Unfortunately sheet metal bending is not always going to be the same in every shop. The largest variations come from the materials themselves. Protective coatings, variations in the alloy and thickness as well as many other small factors all add up to give you Bend Allowances unique to your operation. This chart will get you close enough for most applications and may not require fine tuning on your part, however if you are truly dedicated to precise bending, download the excel sheet and begin plugging in your own values.

With all of the technological advances being made in the sheet metal fabrication and manufacturing industry, it should come as no surprise that a variety of mobile apps have been developed for on-the-go use. However, what has been somewhat surprising is the sheer number of apps now available. Therefore, we at EVS Metal thought this would be a good time for an overview of the well-rated apps that are currently out there. ff782bc1db
