Evaluation of standard compensation of thermal distortion caused by rotating spindle on volumetric measurement of a floor type machining centre

Original language description

A direct implication of recent increasing demands on machining accuracy is an effort to minimize errors by any possible means. Since a significant and possibly major part of error is caused by thermal deformation, its compensation has high priority. Various methods of thermal error compensation have been developed including a complex dynamic method using transfer functions. Such a method, with relatively minor calibration requirements, has proved to be reliable in the prediction of thermally induced error at one point of a machine tool workspace. This paper focuses on extending the compensation method usability across the machine tool workspace. A possibility of extrapolating the predicted deviation of a tool centre point in the direction of Z axis in the calibrated location to the whole workspace is examined. No additional gauges and external inputs are used. The concept results are applied to a volumetric measurement of the deviation of the tool centre point in the Z axis of a floor type machining centre that was submitted to a test sequence of thermal loads applied by various spindle rotational speeds. The concept has proven to be capable of increasing the quality of the thermal error compensation in comparison with the one point calibrated model.
