Critical Dimensions Sheet Metal Forming – Outside dimension should be used unless the inside dimension is .
Here you can specify many of the sheet metal specific properties including bend radius, K-factor, and bend relief dimensions. These can be fixed values or formulas based on the material thickness. (Note: you can find all of this information for your chosen material and thickness in our bending calculator as well.) Use the sheet metal module or tools in the software: Most 3D CAD software provides related tools and functions for sheet metal design. For example, Creo offers a variety of methods for controlling the unfolded dimensions of sheet metal, including the modeling and unfolding methods of large arc sheet metal parts, bend deduction method, etc .
Bends. Bends in sheet metal are manufactured using sheet metal brakes. A +/- 1 degree tolerance on all bend angles. Other standard bend radii available, some of which will add additional cost to your part, include: . Dimensions. Relief cuts for bends must be at least one material’s thickness in width, and must be longer than the bend radius.A fully dimensioned sheet metal drawing includes dimensions for all bends, holes, countersinks, flanges, and other formed features (such as hems and curls, ribs, dimples, etc.). It is a best practice to dimension to virtual intersection points and show included bend angles.I worked with sheet metal for the first time within NX 11. And I used the automatically generated bend lines in my drawing. Now my colleague noticed the difference between the bend line, and the actual dimension we needed after it was bent. Obviously the difference comes from the thickness of the plate and the radius.

Bend deduction refers to the amount of reverse bend and is a simple algorithm used to describe the sheet metal bending process. According to this method, the flattening length (LT) of the part is equal to the sum of the length of the two theoretical flat sections extending to the “sharp point” (the imaginary intersection of the two flat .For the first bend you can use the default flat pattern and dimension to the bend line. For the second bend and gauging off the bent flange use the configuration of the top view, show tangents, put a center line between the tangents of the unbent section (since this is where you bend line would be) and dimension.
Bend allowance and bend deduction calculations are methods you can choose to determine the flat length of sheet stock to give the desired dimension of the bent part. Other methods include bend tables, K-Factor, and bend calculation. . Bend Calculation Tables.

Safest way to dimension the location of a jog like that is the intersection point of the 2 outside faces. In SolidWorks, you can right click on one, select find intersection, and then grab the other one. This will give you a point out in space that you can dimension. This method is nice because it is completely independent of bend radius.Just make sure to dimension outside to outside bend dimensions and tangent dimensions for non 90 Degree angles in your prints . When you bend sheet metal, shrinking and stretching occurs at the bend. To get accurate parts you need to account for this using bend deductions and k-factors (which vary between tooling and material, thickness). . To develop the flat pattern, first add up the outside dimensions—that is, all the dimensions that make up one side of the sheet metal, as if the part were unfolded and flat. There are several ways to establish a flat blank. To dive deeper on this subject, see “The basics of applying the bend functions,” archived at thefabricator.com. Calculate the bend allowance to account for material stretching and ensure accurate dimensions. Design Considerations for Metal Sheet Bending. Bend Radius: .
