Fig. 8From: Mid-spatial frequency error generation mechanisms and prevention strategies for the grinding process(a, b, c) Maximum of amplitude of the tool generated spatial frequency in respect to the rotation speed of the tool, given for each path speed after polishing; (d, e, f) Mean value of all other significant maximums of amplitude in the spatial frequency interval between 0.5 and 4 1/mm in respect to the rotation speed of the tool, given for each path speed after polishing. The relevant grinding parameters are listed in Table 3. Fourier transformation: Normalized, unity windowBack to article page
