Abstract
This paper focusses on the investigation of thermo-elastic behavior of single components of machine tools. The components are divided into thermal active (spindle, bearings, linear guides, ball screws, etc.) and passive components (all structural elements, which do not produce but transfer and emit heat). To model a whole machine tool structure, the thermo-elastic behavior of each component and the interactions have to be identified. The research field of linear guide and spindle systems includes the experimental investigation on special test rigs. In this paper, the measurement setup, test rigs and experimental results of linear guide systems and an externally driven spindle are presented. The test rigs allow for measurement of the temperature distributions in the components and friction forces for different velocities of the shoe resp. spindle speed and loads. Temperatures are measured by thermo-couples, resistance thermometers and an infrared camera. These results support the compensation or correction of manufacturing inaccuracies caused by the thermo-elastic behavior of linear guides and spindle systems.
