  Suppression of the inflection pattern in ultraprecision grinding ...

  201611 · This study simulated the hydrodynamic pressure in the grinding process and validated the flat surface grinding results by varying the tooth geometry. A comparison showed that the hydrodynamic force was decreased by 20–35% and that the inflection pattern of the ground surface was markedly decreased in rotational symmetric grinding.

  Experimental studies on material removal mechanisms in …

  2021721 · Ultrasonic assisted grinding (UAG) is one of the most suitable methods for the processing of hard and brittle materials such as silicon carbide (SiC). During UAG of SiC, the machining quality is directly determined by the material removal mechanism. However, the research on the material removal mechanism for UAG of SiC is still not sufficiently …

  Effects of minimizing hydrodynamic pressure in ultra …

  200481 · It is already known that hydrodynamic pressure generates due to this fluid flux, and that it affects overall grinding resistance and machining accuracy. Especially in the ultra-precision mirror grinding process that requires extremely small amount of cut per each pass, its influence on the machining accuracy becomes more significant. Therefore ...

  In-process Measurement of Topography of Grinding Wheel …

  The working surface of a grinding wheel is dressed at a certain interval to avoid the burning. Therefore, it is very important to measure both wear amount and topography change of the grinding wheel during grinding process. Grinding fluid, which causes the difficulty of the inprocess measurement, is often used to cool a workpiece.
