Abstract

This paper deals with a new grinding method which adopts a toothed geometry on the grinding wheel for decreasing the hydrodynamic pressure on grinding arc thereby improving surface roughness of a ground surface. Usually, during the grinding process, the fluid generates hydrodynamic pressure which increases grinding resistance which is larger than the net grinding force in extremely small cutting depth. Furthermore, this hydrodynamic pressure worsens wheel rotational balance which affects ground surface topography. Therefore in this paper, new wheel geometry, specifically tooth shape, is proposed on the point of decreasing hydrodynamic pressure effect. Experimental data indicates that the proposed wheel geometry is effective not only on decreasing the hydrodynamic pressure but also improving surface roughness.
