| Abstract: | Based on the volumetric error model of multi axis machine tools, an approach to determine the volumetric errors of CNC machine tools is proposed by measuring displacement errors of some determined diagonal lines in the work space by using a laser interferometer that provides a solution to the roll calibration of a vertical axis. The results from the experimental tests show that the method, which is feasible and accurate, shortens the calibration time and reduces the equipment needed. |
