Full title and description

STB VDI VDE 2631 Blatt 9 2014-10 — Form measurement: Examples for measurement and analysis conditions. This guideline gives worked examples and recommended measurement/evaluation conditions for common form characteristics (roundness, straightness, cylindricity, flatness) to help users derive appropriate measurement and analysis settings from function and tolerance requirements.

Abstract

The document provides exemplar tables and example cases that define measurement and evaluation conditions for form metrology. It illustrates how measurement and analysis conditions can be selected based on the functional requirements and tolerances of the feature being inspected, supplying templates that users can adapt for their own specifications and procedures.

Scope

Provides example measurement and analysis conditions for typical form-measurement tasks. The guideline covers exemplar setups and evaluation parameters for common geometric characteristics (roundness, straightness, cylindricity, flatness) so that measurement conditions are consistent with the function and tolerances of the measured feature. It is intended to give users templates and decision support when specifying evaluation conditions for form tests.

Key topics and requirements

• Worked examples and exemplar tables for measurement/evaluation conditions for roundness, straightness, cylindricity and flatness.
• Guidance on deriving measurement conditions from part function and tolerance requirements.
• Recommended analysis conditions (filtering, evaluation lengths, datum and referencing considerations) appropriate to typical applications in form metrology.
• Cross-references to related parts of the VDI/VDE 2631 series (principles, filters, uncertainty, axis deviations).

Typical use and users

Used by metrology engineers, QA/quality-control engineers, CMM and form-measurement laboratory staff, product and process engineers, and standards committees. It is applied when defining measurement procedures, writing inspection specifications, training measurement personnel, or creating acceptance-test templates for geometric form characteristics.
