碩士 === 國立勤益科技大學 === 冷凍空調系 === 105 === With the of machine tool industry, machine tools will be developed toward high-speed, high precision machining and multi-tasking. On the other hand, machine tool coolers are the best strategy for thermal management in avoiding the thermal deformation for machine tools. However, due to energy efficient component s were raised in recent year, it’s a commonly-seen problem for improper selection for machine tool cooler only based on previous sizing experience. In this study, the temperature variation of built-in motor spindle through experimental method was examined and analyzes extensively during actual machining process under different ambient temperature for one year. After analyzing the field testing data, computer simulation for the cooling system of spindle has been conducted extensively to identify the better thermal management strategies. Besides, predictive model using regression analysis has been implemented comprehensively to analyze thermal behavior of spindle. The experimental results reveal that the machining loading is about 50-60% of rated loading and there is a strong relation between temperature variation of spindle and ambient temperature. The developed predictive model provides a reliable estimation for temperature deviation of spindle under different ambient temperature. It is a valuable information for selecting suitable machine tool cooler under different ambient temperature according to the experimental temperature data of spindle in each season.
