Abstract
In the paper a concept of length and angle metrology in fourth industrial revolution known as Industry 4.0 was presented. Problems and conditions as well as limitations connected with measurement possibilities from devices and man point of view were shown. Scale as metrology term with its division to different ranges, i.e. macro, micro and meso were described. For each of these areas digitization and its tasks were presented.
Highlights
The fourth industrial revolution, the slogans of which have been appearing for several years, is slowly taking its first steps in the field of practical activities
According to the Industry 4.0 strategy, metrology is to become a fully integral part of production, even if not all measurement systems will be physically embedded in the process
The main role will be played by automation, which will make the control of the finished product less and less frequent
Summary
In the paper a concept of length and angle metrology in fourth industrial revolution known as Industry 4.0 was presented. Developing the convictions created several decades ago in the introduction of quality assurance systems that the weakest link in the new systems of manufacturing and product evaluation is man, in the metrological strategy of Industry 4.0, human influence should be important at the stage of constructing and creating programs for technological machines and measuring devices, but in the course of their operation it is to be reduced to supporting activities. In order for man to be able to function safely in such an environment, the concept of cooperating robots appeared, more and more willingly used in length and angle metrology They carry out automated measuring activities and support the operator in activities requiring strength or strength. For elements that can not be hidden, built-in spring mechanisms are detected, which detect overload at the contact and disable the movement of the sub-systems of the measuring instrument
