Abstract
A disclosed example method for compensating a temperature-dependent change of position on a machine tool having at least one first linear axis involves detecting at least one first temperature at a first temperature measuring position of the first linear axis of the machine tool. The example method also involves obtaining a first difference in temperature between a first reference temperature and the first temperature and determining a first compensation value based on the first difference in temperature. In addition, the example method involves compensating a temperature-dependent change of position based on the first compensation value, the first compensation value is additionally determined based on an axis position of the first linear axis.
