Accuracy Measurement and Error Compensation of Three-Axis CNC Milling Machine

Jin Ying Chen

Abstract

Through the methods using combination ball-bar with laser interferometer, we carry on accuracy measurement and error compensation of three-axis CNC milling machine. We finally find out the main factors affecting the machining accuracy of machine tool. In the meantime we can improve repeatability of positioning accuracy and the machine's positioning and meet the processing needs by means of the existing error compensation of the CNC machine tools.
