碩士 === 國立中正大學 === 機械工程學系暨研究所 === 102 === For precision machining industry , the accuracy of machine tool is their top priority . Besides the high accuracy needs of machine parts , proper assembling also plays an important role on precision machining industry. Bad assembling will cause huge deviation on machine tool. If we can develop an detection system which can judge the assembling of machine parts is well or not, that would helps a lot for precision machining industry. In this research we develop a hybrid sensor which combines a ADXL-335 three-axis accelerameter and a glass-type PT-1000 thermometer . We integrate ADXL-335 and PT-1000 on a PCB chip with a diameter of 0.85 centimeter and assemble it with epoxy into a cylinder mold. After removing , a cylinder shape Hybrid Sensor with a diameter of 1 cm and 1cm tall. Besides single Hybrid Sensor , we also develop a set of module with 5 Hybrid Sensor and some noise-resist circuit. We use the Hybrid Sensor module to measure the temperature and acceleration of testing machine under different parallelity of slipper track. We use a signal decomposition method called EMD to analyze the vibration signal. After studying the EMD secondary signal, we can judge the parallelity of slipper track.
