Abstract
Many multi-task machines have been developed recently because of demands for reduction of the number of machining processes. Therefore, in this study, the new measuring method of thermal deviations with the linear axis motion is devised for a multi-task machine. This method is possible to do the same measurement as the method standardized in ISO230-3. Using this measurement system, thermal deviations with the reciprocating mo tion of the carriage are measured on the actual multi-task machine with the general structure. From the results, we obtain following conclusions. The method we proposed here has validity. The estimation of the thermal deformation mode is possible with synthetic evaluation of the measurement result from this measuring method.
