This paper proposes a novel wheel-shaped grinding/polishing tool, which is designed tobe controlled on both the self-rotation around its axis and the co-rotation around vertical axis Z atthe specified speeds respectively. Therefore, the surface material of the workpiece can be removedby virtue of self-rotating motion. On the other hand, the co-rotating motion will also change themanufacturing orbit continually. To analyze the characteristics of the tool, material removal in themanufacturing zone on the workpiece surface is first established through theoretical modeling.Subsequently, a good evaluating method, i.e. power spectral density, for analyzing the frequencyspectrum features of material removal function in computer-controlled optical grinding andpolishing is introduced in detail. By simulation, the power spectral density of the material removalfunction was cut into several parts, some frequency with low amplifies of material removal functionwere removed, and the modified material removal function reflected the actual processing status,which was helpful in removing some residual high frequency errors on the surface of the workpiece.Finally, the high amplitude such as at high frequency of 110mm-1 and 210mm-1 was reserved andsome other low amplitude frequencies were removed
