| Summary: | 碩士 === 國立中興大學 === 機械工程學系所 === 98 === In recent years, due to the rapid development of the electronics industry and the requirements of machining accuracy and quality contribute to the growth of machine tool, the thermal error problem becomes more and more attention. Because the rotating component in rotation produces a quite of heat, reducing or inhibiting its heat generation is the most important problem.
In this study, focus the ITRI thermal restrain feed system, with simulation and analysis of the various conditions, with online experiments verification. In simulation part, firstly calculating the amount of heat, then input to the software to analysis the relationship between the positioning accuracy with the experiment. The results show with the mass flow rate 2 (L/Min), it can effectively reduce heat and improve the positioning accuracy less than 1μm. The result proves it can help the machine tool to achieve high standard of machine tool technique.
