Precision Engineering

Division 5

Dimensions from several metres down to nanometres — precise dimensional metrology as backbone of a reliable and sustainable industrial production.

Tasks

It is the main task of the division to assure the traceability of industrial measurements in different length and angle ranges by application of special measuring instruments, methods and standards. Also hardness metrology belongs to its scope. The aim of these activities is to offer traceability to industry in an adequate way and to jointly solve respective measurement challenges.
The research and development activities needed for these tasks focus on new measurement methods, instrumentation and standards. In addition the division is engaged in manufacturing and measurement tasks in the field foundations of metrology. The Scientific Instrumentation offers construction and manufacturing services for special components and precision instruments for the whole PTB.

In June 2020 the EMPIR network project "Support for a European Metrology Network on Advanced Manufacturing" was started. This project targets at the strengthening of European manufacturing industry through innovative metrology. For the first time, a coordination at the European level will be realised, which enables an infrastructure for sharing of metrological knowledge. Moreover, a research agenda will be developed in a dialogue with stakeholders from different industry sectors, which will support and accelerate the development and integration of metrology for advanced manufacturing.
