How to detect the accuracy of CNC machine tools, various industries are being the user acceptance and maintenance of CNC machine tools much attention to problems. Keywords CNC pensation Modern CNC machine tool bines puter, servo systems, automatic control systems, precision measurement systems and new types of institutions of advanced Technology to processing of plex shape, precision, smallvolume parts, and has the processing of high precision, high production efficiency, adaptability and so on. With the rapid Development of manufacturing industry, CNC machine tools in the machinery manufacturing Industry has been widely used, and the accuracy of CNC machine tools are increasingly high requirements. How to detect the accuracy of CNC machine tools, various industries are being the user acceptance and maintenance of CNC machine tools much attention to problems. Accuracy of machine tools include the geometric accuracy of machine tools, machine tool positioning accuracy and precision cutting machine tools. On the basis of these precision of test items, test methods and precautions to conduct a prehensive description. 1 A geometric accuracy of CNC machine tools The geometric accuracy of CNC machine tools to reflect the key mechanical ponents (eg, bed,
