| Abstract: | Analysed the influence of the abrasive wheel microvibration to the workpiece surface quality on ultra-precision grinding process, and established a mathematical model describing how vibration led to the error of workpiece surface profile. Designed the corresponding microvibration experiment system of grinding process, which can simulate radial vibration, transverse vibration and oscillation of wheel on machining process. The results showed that, with appropriate wheel vibration frequency or appropriate workpiece rotate speed, the surface precision of workpiece can be improved. |
