This paper establishes the simulation error data models of roundness error, spindle rotation error and noise signal from the characteristics of error signal based on three-point method. From the Matlab simulation, the influence of installation angle error of the sensor, roundness error magnitude and the noise on the segregation accuracy was studied in detail. This makes up the deficiencies of previous studies, and also provides a good foundation for further improving the accuracy of three-point method.

Spindle rotation accuracy is important in machining process. Indirect compensation of spindle rotation error has been widely adopted in the field of machining accuracy improvement. However, there are some limitations on indirect compensation, and a little research on direct compensation can be found. This article utilizes active lubrication technology to improve the spindle rotation accuracy. Hydrostatic journal bearing with control recesses and servo valve drove by piezoelectric ceramics are adopted to compose the compensation element. The simple control strategy PID is adopted to provide control signal for servo valve. Both simulation and experiment are designed and conducted. The results show that proposed bearing system has the ability to improve the spindle rotation accuracy.
