High Precision In-situ Measurement and Compensation Method for Spherical Grinding Wheel

Abstract— In parallel grinding, the processing accuracy is directly related to the spherical grinding wheel shape accuracy. Therefore, it is very necessary to obtain the change information before ultra-precision grinding. This paper proposes an in-situ measurement scheme of spherical grinding wheel, including building an in-situ measurement system based on laser tool setter. The systematic error of this scheme is analyzed, the installation error model of laser tool setter is abstracted. Furthermore, the compensation of measurement data and high-precision in-situ measurement of spherical grinding wheel are realized. Finally, the error angle value is calculated by calibrating the 12.5mm standard ball for calibrating, and then 3mm radius standard balls are measured for verification. Experiments show that the measurement accuracy after compensation can be improved to 1.2μm.

Index Terms— parallel grinding, laser tool presetter, error compensation.
