| Summary: | 碩士 === 南開科技大學 === 車輛與機電產業研究所 === 101 === A high speed cutting tool holder of a machine tool is a high-precision, high-speed rotating machine part and the result of dynamic balancing has seriously influence on the machining performance. Generally, the try and error time consuming method is usually adopted for the tool holder balancing design in industry. Therefore, a theoretic tool holder balancing formula should be derived for directly calculating the added/drilled off masses, for reducing the numbers of balancing steps and shortening the balancing cycle-time. In this paper, a theoretic balancing formula for a high speed cutting tool holder is derived and its automatic calculating program is also written. The procedure of the program is iterated several times to verify the amount of imbalance are lower than the required specification. Finally, the results of the balancing design are verified by using the mechanism simulation software COSMOS MOTION.
