Measurement and Compensation of The Positioning Accuracy of The CNC Machine Tool
ABSTRACT
With the development of numerical control technology and equipment in CHINA, CNC machine tool as a high accurate, high efficient, high stable automatic machining equipment, it has been a absolutely necessarily modern equipment in mechanism industry. The positioning accuracy of the CNC machine tool is an important aspect which affects its high accurate, so it is necessary to measure and compensate the positioning accuracy of the CNC machine tool. In the text, the development status of the CNC machine tool in CHINA, the definition of the positioning accuracy of the CNC machine tool, the composing of the error and its measuring items are introduced. And emphases on the research of the ML10 Laser Interferometer measurement method and a few primary compensations. Certified the conclusions with the data captured in the school laboratory tested one CNC machine tools.
KEY WORDS:CNC Machine Tools, Positioning Accuracy, Measurements of Positioning Accuracy, ML10 Laser Interferometer, Compensation
