Embodiment Construction
[0024] In order to solve the above problems, the inventor of this case conducted careful design and research, and concluded that the relative speed during the surface grinding process of the workpiece has an impact on the upper and lower shapes.
[0025] Embodiments of the present invention will be described below with reference to the drawings, but the present invention is not limited thereto.
[0026] A method for reducing the flatness error of a double-sided grinding workpiece. Figure 1 is a schematic diagram of the calculation of the double-sided grinding trajectory. When the present invention studies the influence of speed on the upper and lower shapes, the two-sidedness of the workpiece is obtained by calculating the rotational speed of the upper and lower grinding discs and the rotational speed of the workpiece. One surface has a concave surface shape, and the other surface has a convex surface shape. By comparing the relative speed, it is found that the relative speed ...
