Thermal compensation for large volume metrology and structures

International Journal of Metrology and Quality Engineering, 2017
Ideally metrology is undertaken in well-defined ambient conditions. However, in the case of the assembly of large aerospace structures, for example, measurement often takes place in large uncontrolled production environments, and this leads to thermal ...
