Abstract_English:REVO 5-axis measurement system，which is designed to be applied in orthogonal coordinate measuring machines(CMMs)，is a revolutionary high efficiency and accuracy measurement system. The reconfiguration and mathematical model of REVO 5-axis measurement system were proposed for its application in non-orthogonal CMMs. The composition of the original data returned by the system was analyzed，and the scale values were separated out from the synthetized data. Based on the quasi-rigid body theory，the error compensation model of REVO head was established. The validity and effectiveness of the error compensation model were verified experimentally. The average measurement error decreased to 0.001 1 mm from -0.190 3 mm after error compensation. The research conducted in this paper is of great significance for the application of REVO 5-axis measurement system in non-orthogonal CMMs.
