Study on single-plane biaxial balance monitor system in ultra-precision aspheric grinding

An intelligent single-plane biaxial balance monitor system in ultra-precision grinding was put forward. For influence of the interaction of vibration of wheel and workpiece on a ripple on the workpiece surface, this system adopts single-plane balance correction for the principal axises of wheel and workpiece synchronouslly, and it analyzes integrally the balance condition of whole system and the surface error of workpiece by processing the vibration data of wheel and worpiece together. The experimental results show that this system can reduce the surface error of workpiece and decrease the abrasion of wheel to improve machining accuracy. The measuring data prove the correction of integral analyses.
