The paper deals with the influence of the thermal state of the machine on its function and product accuracy. The results of the experimental measurement on a particular machine are presented and consequently a virtual simulation of the thermal state of the working space depending on the time of its operation of the machine is performed. Model examples for changed boundary conditions are calculated with respect to the possibility of reducing energy consumption while maintaining a constant thermal state of the machine. Based on the simulation of the thermal state a structural analysis is performed to determine the effect of thermal conditions on the clearance of the ram guiding.
