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.
