It can be seen from the figure: in other processing conditions remain unchanged, the change in the speed of the workpiece spindle, the surface of the workpiece surface space spatial frequency and amplitude are changed. Thus, in the vibration condition, select the appropriate processing parameters, surface quality will be improved.

Vibration conditions in the processing of the surface profile, the surface spatial frequency and amplitude of the surface space wheel vibration frequency and the ratio of the workpiece spindle rotation frequency, and therefore change the frequency or vibration frequency of the workpiece spindle rotation will cause the surface profile change. The design of ultra-precision grinding of micro vibration test system can simulate the process of grinding wheel radial and transverse different frequency, small amplitude vibration and swing for the study of different processing parameters on the grinding wheel and workpiece vibration characteristics Quality of surface and provide experimental basis. By optimizing the processing parameters, the ultra-precision grinding energy in the vibration as small as possible under the conditions, and indirectly to ensure product quality.</span></td> </tr> </table></td> </tr> <tr> <td colspan="2" height="1" class="spaceRow"><img src="http://picsrv.fora.pl/subSilver/images/spacer.gif" alt="" width="1" height="1" /></td> </tr> </table>
