Take a look at how we got started, before you can begin to layout your pattern you have to find all your true lengths. The only way you can see a true length line is perpendicular to its plane, the best way .Sheet metal parts are unique because they use common flat stock materials. The following design guide tips will often describe distances in material thickness, or MT, for relative measurements. Flat cut sheet parts, such as flat brackets, can be cut thicker (above ¼”) using plasma Figure 2 shows the layout for the two-piece transition shown in Figure 1. The finished fitting is 14 inches long, but the bottom piece is longer than this. . More often, transitions are made in four pieces in order to save both time and sheet metal. Figure 3 shows the plan and elevation of a typical four-piece transition. Each side of this .

Also capable of creating bends in 18 gauge steel in widths less than 12”. The minimum sheet metal bending height should be calculated as 2 times the thickness of the sheet metal plus the bending radius, i.e., H ≥ 2t + R. As illustrated in the accompanying figure, if the bending height is too low, the .

The second side would be traced or a second pattern would be developed .Offset tooling allows two v bends to be formed closer together than regular Press Brake Dies would allow. This creates a z shaped profile in the sheet metal. This type of bend is also commonly referred to as a jog. The two basic forms of offset tooling are .When developing sheet-metal patterns, ensure you add sufficient material to the base dimensions to make the seams. Several types of seams used to join sheet-metal sections are discussed in this section. There are three types of lap seams: the PLAIN LAP seam, the OFFSET LAP seam, and the CORNER LAP seam (fig. 2-66).
Formulas: Bend Allowance (BA) – The amount of added to the sum of the two leg lengths to obtain the flat pattern length. Bend Deduction (BD) – The amount removed from the sum of the two flange lengths to obtain a flat pattern. Material Thickness (MT) – The gauge of the material in decimal form. Bend Angle (B<) – The inside angle between the two legs or flanges of a bend.
