| Summary: | 碩士 === 中原大學 === 機械工程研究所 === 104 === Non-MEMS micro machining technology has been regarded as one of the key technologies for the development of precision industry. However, very less research efforts had been devoted in developing volumetric error measurement method and synchronous movement error calibration. Due to the workspace constraints of a micro machine tool, the current measurement methods used in industry cannot be applied. With use of image identification/tracking, coordinate transformation and sensitivity analysis, the volumetric-error measurement method and system for micro CNC machining center with use of image capture system were developed in this study. The methods provide 4 main functions: (1) volumetric error measurement, (2) error characteristics analysis, (3) Rotation accuracy measurement (4) convenient human-machine interface with graphical display for micro machine tool.In addition to develop the methods and systems, sensitivity analysis was made. Micro machining experiments were conducted on a micro machine tool to verify the feasibility and reliability of the developed system.
