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.

News

As part of the QI-Digital initiative, the potential of digitization for new ways of making the quality infrastructure more effective and efficient is to be examined and demonstrated. Using the example of additive manufacturing, the necessary steps for an optimal interaction of the QI components and data management have now been analyzed and implemented using an additively manufactured demonstrator (replacement) component.
