Machining centres are machine tools for universal use that are able to perform a range of processes, such as milling, turning and drilling. They can be used in automated production lines and for custom manufacture of single parts or small batches. Where components are larger, the loading and adjustment of the blanks and retrieval of the components after machining is often associated with high stresses for operators, such as unfavourable constrained postures, high forces, and the handling of heavy weights. Good accessibility of the loading area and the straightforward use of auxiliary lifting equipment during these tasks is therefore very important.

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.
