摘　　要：REVO五轴测量系统是基于正交式坐标测量机设计和应用的高效率、高精度测量系统.针对在非正交式坐标测量机环境下应用REVO五轴测量系统,提出了REVO五轴测量系统的重构与数学模型.建立了REVO五轴测量系统原始返回数据的构成模型,从返回的合成数据中分离出光栅数据;基于准刚体理论,建立了REVO测头误差补偿模型.通过实验验证了误差补偿模型的正确性和有效性,经过误差补偿,测量误差平均值从-0.190,3,mm降低到0.001,1,mm.本文的研究内容对于在非正交式坐标测量机下应用REVO五轴测量系统具有重要意义.REVO5-axis measurement system,which is designed to be applied in orthogonal coordinate measuringmachines(CMMs),is a revolutionary high efficiency and accuracy measurement system.The reconfiguration andmathematical model of REVO5-axis measurement system were proposed for its application in non-orthogonalCMMs.The composition of the original data returned by the system was analyzed,and the scale values were separatedout from the synthetized data.Based on the quasi-rigid body theory,the error compensation model of REVOhead was established.The validity and effectiveness of the error compensation model were verified experimentally.The average measurement error decreased to0.001,1,mm from-0.190,3,mm after error compensation.The researchconducted in this paper is of great significance for the application of REVO5-axis measurement system in nonorthogonalCMMs.
