Abstract
The theory of cutting is applied to the study on the grinding mechanism. The grinding model which defines the mechanism of the plastic deformation of chip in grinding is presented. Experiments with single grains and diamond pyramids show the validity of the grinding model.
The effects of grinding speed and depth of cut on grinding forces and shear angle are investigated.
Further attempt in this paper is to find limitations of the application of the cutting theory. Owing to the swell-out residual at the track of a grain the grinding model is not explicitly correct. Experiments reveal that the swell-out residual decreases with the increase of grinding speed. This phenomenon is discussed from the standpoint of Kármán's plastic wave in workpiece.
