| Summary: | 碩士 === 雲林科技大學 === 機械工程系碩士班 === 96 === In this work we integrated linear PM motors with air-static bearings and a PC-Based control system. To enhance the stability of the precision machine tool, we include vibration isolation technology in the machine frame, and the system was delivered with a framework of measurement and compensation to achieve completeness, openness, flexibility and performance. In today''s industry, Laser equipment is commonly used in the fields of processing and measurement, and its safety and reliability is suitable for our experiment.
In this study, we investigate positioning accuracy and surface flatness of the machine. We employed ANCA PC-based Control System as the platform to develop methods of measurement and software for automated measurement applications. The use of laser measurement equipment generates calibration data, which will then be integrated into the top-level controller for real-time compensation. Analyzing and comparing the result of axial precision, it showed that temperature effects on the repeatability of the experimental platform were quite significant. To measure the flatness, the integration between measurement and control system was the main effort. The laser equipment was integrated in the control system by application software of our own design to realize real-time compensation of surface flatness. The establishment of such compensation system will help the controller achieve high-precision machining.
