Seven Methods for Verifying CNC Machine Tool Positioning Accuracy
The positioning accuracy of CNC machine tools is a critical measure of the precision achieved when the coordinate axes of the machine tools are controlled by the CNC device. This accuracy essentially reflects the machine tool's ability to achieve precise movements. In contrast to manually fed ordinary machine tools, where positioning accuracy is primarily influenced by reading errors, CNC machine tools rely on digital program instructions for their movements, making their positioning accuracy contingent upon the CNC system and mechanical transmission errors. This distinction underscores the importance of understanding and evaluating the factors that contribute to the positioning accuracy of CNC machine tools, as it directly impacts the quality and reliability of the machining processes they perform. A CNC machine tool, short for digital control machine tool, is an automated machine equipped with a program control system. This system can process programs specified by control codes o...
