Sheet Metal Gauge Tolerances Chart - Engineers Edge

Sheet Metal Guage Tolerances. During the rolling process the rollers bow slightly, which results in the sheets being thinner on the edges. The tolerances in the table and attachments reflect current manufacturing practices and commercial standards and are not representative of the Manufacturer's Standard Gauge, which has no inherent tolerances.

Design Tip 8 Ways to Improve Sheet Metal Parts

Sheet metal parts often require notches to accommodate a screw or other fastener. These should be one material thick or wider and extend no more than five times the slot width into the workpiece. Similarly, the tabs on either side of a notched feature should be at least 0.126 in. or two times the material thickness across (whichever is greater) and again, be a maximum of five times the part thickness in …

Jul 25, 2017 · One of the problems I am encountering is that the angle tolerance for machined & injection-molded plastics needs to differ from that of sheet metal parts. We had a vendor indicate the +/- 1/2 degree was too tight for sheet metal, and needed a variance for forming the part to +/- 1 degree bend angle. I am wondering how other companies do this.

Tabs for Precision Machining Dropout Metal Parts

To provide the tightest tolerances, we recommend precision machining parts so that they remain within the metal sheet from which they are etched. The small amount of metal that is designed to bridge the part to its metal sheet is called a tab. Parts that are tabbed to remain in the sheet also allow for safer handling and easier inventorying.
