New Measuring Method for Thermal Deviations Caused by Linear Axis Motion in Multi-Task Machine

摘要

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, six thermal deviations with the reciprocating motion of the carriage are measured simultaneously on the actual multi-task machine with the general structure. From the results, we obtain the 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.
