Abstract

For manufacturing of high-value components, such as in the aerospace, automotive, shipbuilding and nuclear power industries, there is a significant demand for integrated traceable measurement to provide fast feedback during the manufacturing processes. Most modern machine tools are equipped with a probing system. However, one of the key challenges is that the traceability of measurement on a machine tool is not ensured yet, and therefore, the measurement results are not reliable for process control and product geometry verification. A laser tracker is a portable optical measurement system and capable of performing high accuracy and long range 3D measurements. As such, it is a suitable alternative solution for large component measurement. The aim of this paper is to test measurement uncertainties for a large component using different methods, including use of tactile on-machine tool probing and optical laser tracker, in ‘shop floor’ conditions. The measurement results have been verified using a large gantry coordinate measuring machine (CMM).
