A specially developed laser measurement technique was used for a quick measurement of 3D volumetric positioning errors of a CNC machining center under various spindle loads, machine movement and ambient conditions. Correlation calculations were used to determine the key temperatures and the various positioning errors. Preliminary results showed that large machine temperature changes caused somewhat small linear displacement and straightness error changes but large squareness error changes."@en . "[E7C91BE18C22]" .
