以三坐标测量机21项误差理论为基础,分析总结测量机误差补偿技术实施过程中的关键技术,探讨该项技术的应用要点,编制误差补偿软件模块,验证坐标测量机21项误差补偿的实际效果.结果表明在正确测量和处理各项误差的基础上,21项误差补偿方法可明显提高系统精度.%According to 21 errors compensation theory, analysis and summarize the key techniques in error compensation were analyzed and summarized. The important steps in the errorscompensation were discussed. The error compensation calculating software was programmed. The effectiveness of 21errors compensation was verified. The result indicates that the measurement accuracy of the equipment could be moreprecise obviously after measuring and calculating all errors correctly.
