Error Compensation to Three Coordinate Measuring MachineZHAO Tianehan , WU Hui , FENG Jun , WU Wenbing 1. Eleetromeehanieal School, Jianghan University, Wuhan 430056, China; 2. Beijing Nanhanglike Mechanic Co, Ltd, Beijing 100076, ChinaAbstract:Some modification to the three coordinate measuring machinec （CMM）, was accomplished with changing the measuring system and modifying the corresponding mechanical parts. A better error compensation model was constructed which applied software to measure the error. As a result, it increases the volumetric accuracy by 2 or 3 times. The method is convenient and reliable to improve the accuracy of the CMM through the error compensation.[著者文摘]
