Corners / Bend Reliefs Do we use bend reliefs?  • What happens when we just tear them? • What if it is somewhere in the middle?

Does MFG adjust bends?  • Did they figure out with 2D they had to add here, or subtract there, add tool over there?

- MFG may have to Re-Zero their thinking because of this. - Does this information travel back to engineering or stay on the floor

Bend Tables? • What are bend tables • How does the K-Factor help me? • Can you rely on the k-factor without doing test bends

Do we mark bends? • Are you marking bend locations for the Press Break?

Quality Control, Flat to 3D model  • Are you following through to make sure the finished product is correct?

Flat Reps  • When should I make a change to the flat versus the 3D model? • Which environment should I use? Inventor vs. AutoCAD vs. CAM systems

Which finish am I using? • Stainless, Powder coat, Paint, Bare steal, laminate, anodized, galvanized, chrome

plated? • How do I plan for this in my design?

Does Temp affect the parts?  • You are adding heat when making these (laser, plasma, Punching) will this affect the

design? Etching? 

• Are you etching with a laser or marking tool? Post Finishing / Welding? 

• Do we need to oversize the blank to account for post finishing ? • Add so much weld need to reduce part size to allow room for it?

Assembly design vs. Part by Part design  • When you go from designing each part independent to designing them as a whole what

happens? • Do you still make them one by one, or nest the entire thing?

What is the K Factor or Bend Allowances When sheet metal is bent, the inside surface of the bend is compressed and the outer surface of the bend is stretched. Within the thickness of the metal, lies its Neutral Axis, which is a line in the metal that is neither compressed nor stretched. If you have a piece with a 90 degree bend in which one leg measures A, and the other measures B, then the total length of the flat piece is NOT A + B. To work out what the length of the flat piece of metal needs to be, we need to calculate the Bend Allowance or Bend Deduction. This will tell us how much we need to add or subtract to our leg lengths (A & B) to get exactly what we want.

The location of the neutral line can be different depending on the material itself, the radius of the bend, the ambient temperature, direction of material grain, and the method by which it is being bent, etc. The location of this line is what is referred to as the “Kfactor”. K-factor is a ratio that represents the location of the neutral sheet with respect to the thickness of the sheet metal part.

To find if your manufacturing process works best with Inventor’s Bend allowance is to reverse engineer a sheet metal part. Measure strip of material, bending it, and measuring it will give you the correct bend allowance. These bend allowance can be measured for many materials and scenarios and then be used in an Inventor bend table

Reverse Engineering the K­Factor First, cut a strip of material and measure its length and thickness as accurately as possible. The width of the strip is not that critical but generally somewhere around 4 inches or so will work. Then, bend the strip to 90 degrees, and measure its Length X and Length Y as shown in the diagram below.

Buying new tools • Are we limited to what tools we already own, if we do buy a new one what is the turn

around on getting it? If you are designing something that you will need a new special tool for, you should notify manufacturing as soon as you can. You can get tools in as little as a few days for standard shapes, but it can take weeks for special shapes, and longer for form tools.

Tonnage  

• If we own an older 50 Ton Machine can it really hit with all 50 Tons? If you are working with tough or thick materials you need to know what the limits of your machine are and if it is up to those limits. You can work with you machine dealer you use for maintenance to have the tonnage tested. You may also want to design your parts with thinner material to keep from over tonnage your machine and or tools.

Material Availability  

• Do we use standard sheets, do we have to order, what if we run out, what other sizes can we use?

If you are designing something on material that cost $1,000 sqft, then you need to make sure manufacturing knows to handle parts with care. If one gets damaged it could be a week or more to get replacements depending on where in the world it comes from. You may design a flat 60” x 190”, but they may come back and say we have the extra stock 60” x 120” sheet can we use them and redesign the parts to fit them. The cost and time savings may be worth doing a little redesign. Grain consideration  

• What happens if part needs to have gain in the Y axis and it is over the table limits? Stainless and titanium manufactures have to watch material grain direction. This must be taken into account of the design. If you design a part with grain running east west, yet taller in the Y, this can be a problem if the Y dim is taller than the y on machinery you own. Part Size  

• Will it fit in our machines, will it fit out the door of the shop, and will it fit on a truck? As above, will it fit on the table of a punch press or laser? Then you have to think can it fit out the door of the shop, on a truck, or can your forklift pick it up. You may have to design it to be broken down into smaller pieces.
