A relevant characteristic of Industry 4.0 is the extensive use of internet of things (IoT), sensors and actuators to connect physical assets with their digital twins, creating collaborative entities known as cyber-physical systems (CPS). In this context, the role of production metrology goes beyond to the traditional application of measuring product characteristics to evaluate their conformity with specifications or to decide on process adjustments. It becomes a key enabling technology.
The presentation will explore the two-way relationship that production metrology has with the Industry 4.0 paradigm. On the one hand, as a key provider of data to support descriptions, diagnostics, predictions and prescriptions on the fly. On the other hand, as a process that can benefit by the cyber-physical approach to reach higher levels of performance and reliability at an affordable cost. Examples will be provided to illustrate the delicered concepts.
