碩士 === 國立虎尾科技大學 === 自動化工程研究所 === 102 === The manufacturing technology of the five-axis CNC machine tools has progressed in recent year. And how to measure the error for improving the accuracy of the five-axis CNC machine tool become an important task. The original interface of the developed NON-BAR has some problems as following:(1)different of the gain value;(2)accuracy of the axial error; (3)sampling error by manual;(4)inconvenience to analysis the measurement result, and (5)complicated operation steps. In order to improve those problems, this follows the ISO/CD 10791-6 for design the interface with diffident program pages as following:(1)setup for the gain value: integration of the dynamic and static detection to setup the gain value simultaneously;(2)static detection: according to the Minimum Zone Circle (MZC) of ISO R1101, the axial error can be calculated accurately;(3)setup for the link: to link with controller for auto-sampling and reduce the sampling error by manual;(4)dynamic detection: to add directly analysis function within data drawing program;(5)backlash detection: to link with HEIDENHAIN(iTNC-530) controller or FANUC(18i) controller for auto-measuring and compensating backlash error, and(6)temperature detection: to measure the error trend due to temperature changes for a long time of the machine tool.   In this thesis the operation of the novel developed interface become more friendly. Results show the backlash of the linear axis can be compensated less than 1μm, the backlash of the rotary axis can be compensated less than 0.001° and the shift of the axial can be compensated less than 10μm .
