Metrology in digital production

Produktbeschreibung

Executive Summary

This is the translation of the publication „VDI-Statusreport Fertigungsmesstechnik in der digitalen Produktion, 2021-11 [VDI/VDE GMA 2021], original
in German language.

Objective
The aim of this document is to make the processes and structures for digitised integration of measurement technology into production transparent. For this purpose, the existing processes and structures as well as the software interfaces used, and the underlying models are presented. Based on this presentation, generally usable models for the digital representation of measuring systems and measurement orders in production are developed. The partially executed details of these models are to be understood as exemplary explanations. They will differ depending on the application and environment.

Content
Although digitalisation in its original meaning (analogue-digital conversion) has long played a leading role in measurement technology, paradigms such as Industry 4.0 require a comprehensive consideration of all aspects of measurement technology with regard to the digital acquisition, processing, distribution and representation of data. This includes the representation of the measurement data itself as well as the measuring systems and measurement orders in the form of digital models.

The basis for successful digitalisation is the methodical integration of metrology processes and the associated product inspection into digital production. The technical networking of all devices or systems is a necessary prerequisite for this. Established processes or standards defined by norms should be taken into account. For example, the reference architecture Industry 4.0 (RAMI 4.0) provides a framework for the realisation of horizontal and vertical integration and the associated communication. Horizontal communication refers to communication on the same structural organisational level, while vertical communication goes across different levels.
