The Parameters Calibration and Error Compensation of Circular Gratings for Parallel Double-joint Coordinate Measuring Machine(CMM)

摘要：

In this paper, the mathematical model with errors for parallel double-joint coordinate measuring machine (CMM) was proposed. The main factor of the impact of circular grating measurement error—radial install eccentric error—was analyzed. The error was measured and the data obtained from measurement was used to curve fitting and form the error compensation formula. Experiments show that the method of error compensation has good usability and accuracy.
