| Outline of Final Research Achievements |
In the face grinding proses of cemented carbide with diamond plating grinding wheel, which is superior in cooling characteristics, it is obtained that information to design of the new type grinding wheel to deep cut grinding experimentally, with the analysis of grinding state, by measuring of such as grinding force, grinding force distribution which has pressure dimension, observation of grinding wheel surface, EPMA analysis of adhesive material on the grinding surface of the wheel,surface roughness and so on.
As a result, when feed rate is constant, and it added setting depth of the cut, a steady state did not develop, and, the adhesive material due to grinding chip distribution at bottom of grinding wheel near land corner R, it became clear that peak value reduced and also width of peak became broad. In the case of setting depth is constant and it added feed rate, grinding results are similar. And two prototypes of grinding wheels for deep depth of cut grinding are produced.
