millimetrelevel
Millimetrelevel refers to measurement and positioning accuracy at the scale of one millimetre. In metrology and related fields, equipment and methods described as millimetre-level are designed to produce results with an uncertainty on the order of 0.5 to 1.5 millimetres, depending on distance, material, and environmental conditions. The term is distinct from micrometre- or centimetre-level precision and is commonly encountered in manufacturing, surveying, aerospace, construction, and robotics.
Common methods to achieve millimetre-level accuracy include coordinate measurement machines (CMMs) for local measurements, laser trackers
Calibration and uncertainty management are central to millimetre-level metrology. Achieving traceability to national or international standards,
Applications span quality control in automotive and aerospace manufacturing, assembly alignment, civil engineering surveys, and large-scale
