The effect of positioning error and noise on the accuracy for spindle rotation error measurement with three-point method

On the bases of studying the effect of the misalignment of probes, setting-up eccentricity of standard ball and noise on the accuracy for spindle rotation error measurement with three-point method. From the characteristics of error signal, we establish the simulation error data models of roundness error, spindle rotation error and noise signal. Then using Matlab and VC++ joint programming, take full advantage of the powerful computing of Matlab and the fast implementation, user-friendly features of VC++ to analysis the analog error data. This makes up the deficiencies of previous studies, and also provides a good foundation for further improving the accuracy of three-point method.
