Understanding sheet metal tolerances is crucial for ensuring that parts fit together perfectly in any mechanical project. This article will explore the different types of tolerances used in flat and formed stamping parts, from .ISO 2768-2 is for simplifying drawing and fixes general tolerances in 3 tolerance classes (H, K, and L), this part including General Geometrical Tolerances range of flatness & straightness, .
Unlike precision machining, sheet metal fabrication begins with sheet stock, which can have variations in thickness, and the manufacturing processes for forming features also have specific tolerancing constraints.You should define tolerance class as per design requirements and manufacturing capability. For example, the manufacturer recommends ISO 2768-mk for sheet metal parts and ISO 2768-fh .
Even though the term is used all the time, the reality of manufacturing tolerances can get quite complicated depending on the process in question. This post will compare machining, 3D printing, and sheet metal .

We can obtain tighter tolerances (depending on part geometry/ construction), so feel free to contact us for more information or .Sheet metal material stock has general tolerances for thickness. The following table is a quick reference for standard aluminum 5052 material thickness tolerances. Standard stock material tolerances may vary between alloys and treatments. Sheet metal with tighter tolerances sheet can be specified if required. Stock Material Thickness TolerancesFor example, the manufacturer recommends ISO 2768-mk for sheet metal parts and ISO 2768-fh for machined components. In the above example, “m” and “k” have defined the tolerance class. You can calculate the critical dimension tolerance using tolerance stack-up analysis. You can also use a tolerance stack-up calculator for this purpose.
This post is to help you understand what the holdable tolerance can be for your sheet metal parts. However even for an experienced designer, it may be difficult and time-consuming to decide the tolerances for each and every dimension, .
