چکیده انگلیسی
To improve the productivity of large-part manufacturing, we develop a novel on-machine dimension measurement system. The aim is to establish a traceable and automated procedure in a conventional factory space to ensure the quality of actual products. The on-machine system is structured to measure a steam turbine rotor mounted on a large computer numerical control (CNC) lathe. The system includes a laser tracker as the length-measurement apparatus, a probing unit, and a length-calibrating artefact. By carefully considering the volumetric errors of the machine tool in each case, some measurement results regarding the axial-wheel positions and shaft diameters are described. The new system is compared with the conventional manual method using a large micrometre. To validate the on-machine results, other assessment strategies for unloaded machine tools are also implemented using a conventional length-measuring interferometer and a Lasertracer. The uncertainties of the measurements are also discussed.
