In this study, several kinds of materials are circularly ground with a diamond cone indenter and the wave form of grinding force is recorded. It can be expected that the wave form reflects the difference of grinding mechanism among various grinding conditions or the kinds of materials. The vertical component of grinding force differs markedly from the horizontal component in its wave form. That is, the former reaches maximum rapidly after the beginning of grinding, while the latter only gradually increases and becomes maximum around the deepest grinding point. The difference in the wave form is thought to be due to the following two causes : (1) slipping of the indenter tip on the ground surface, (2) strain rate dependence of grinding force. The strain rate dependence is analytically discussed and the analyzed result is able to explain the difference. It is also discussed how the ground materials and sharpness of the indenter tip affect on the wave form, maximum grinding force and the ratio of vetical/horizontal component.
