ISO GPS Practice
Folded sheet metal part
Practical example of the ISO GPS-compliant specification of a Folded sheet metal part:
Two variants of datum establishment, typical hole patterns, and the application of floating tolerancing for Folded sheet metal parts are covered. In addition, bent areas are compared using angular and profile tolerances, and the standards-compliant specification of bend radii is explained.
When purchasing this product, you will receive a video (step-by-step guide) and a PDF file with two variants.

Detailed Description
A folded sheet metal part is specified. Establishing a datum system (using datum targets in V2) is compared in 2 different variants and typical features such as hole patterns are described. To meet the typical (product specific) requirements of bending sheet metal components, a „floating pattern“ tolerance is used.
The correct specification of the folded areas is derived and shown in 2 different variants.
The classic tolerancing approach using angle specifications and a geometric description using profile tolerances is compared.
An ISO GPS compliant specification of bending radii is shown.
Length of explanation video (Step by Step guide) : Approx. 39 min.
Variants: Yes - 2 Variants
Difficulty Level: Variant 1: Suitability 1-2 | Variant 2: Suitability 1-2
Description of the level of difficulty (suitability for the user):
1 – The user has basic knowledge but has not yet used ISO GPS frequently in practice and takes first steps.
2 – The user has basic knowledge but is not proof about using ISO GPS and would like to gain more general confidence.
More „special“ or complex modifiers (these are usually listed in the example description) are applied selectively.
3 – The user has sufficient knowledge, can already use frequently used ISO GPS tools without difficulty,
and would like to deepen knowledge selectively based on typical functional descriptions,
which is usually also product-specific (e.g., snapping features (latching hooks) on a plastic injection-molded part, special demand hole patterns, i.e. multi-level patterns etc.)
used in the example (i.e., listed in the description) (e.g., direction only or certain combinations of dimensional tolerancing, as well as SIM or similar modifications).
4 – The user has extensive knowledge, has been working with ISO GPS for a long time,
and would like to learn about very specific applications or modification operations, which usually describe more complex functional requirements and products.
This requires, for example, situation features, reference elements, filter information, association modifiers etc.
