Milling machines are generally designed to be operated by experienced and highly qualified skilled personnel. The Datron dental milling machines are an exception, since they possess the full functionality of a 5-axis machining centre, but must be set up, adjusted and operated by laboratory technicians. Combined with the high cost and productivity pressure under which dental laboratories often work, an unsuitable machine control system can lead to high mental stresses for the workers. For this reason, the Datron control concept was revised and simplified.

The Technical Report ISO/TR 22100-3 describes how ergonomic principles can be applied during the risk reduction process according to ISO 12100 and how ergonomics standards can be applied to machinery. It helps designers take decisions with respect to ergonomics during the machine design process and can also be used when no relevant type C standards are available.
