Measurement and analysis of machine tool errors under quasi-static and loaded conditions

•A novel methodology for the prediction of machine tool errors under quasi-static and loaded conditions.•Measurement and analysis of the combined effect of geometric errors and quasi-static load induced deviations on machine tools.•Estimation of deflections through the determination of the position- and direction-dependent static stiffness of machine tools.•Introduction how the static stiffness characteristic of machine tools is mapped on the part geometry.
