The Cutting Mechanism of Abrasive Grain : (1st Report, Experimental Observations of the Stock Removal and the Swell-up Phenomena)

Abstract

The investigations of the basic cutting mechanism in the finishing processes using grains for the cutting edge are the fundamental measures for improving the finishing efficiency and for elevating the smoothness of a finished surface. The model cutting tests of grains have been carried out under such conditions that the cutting edge angle and the cutting speed may reproduce the original form of the cutting states of the finishing operations such as grinding, superfinishing and single-point cutting. As the result of these tests, the relations between the stock removal or the swell-up and the cutting edge angle or the cutting speed are clarified, and the influence of cutting conditions on the ratio of the tangential and the normal cutting force is found. Moreover, the relation between the cutting mechanism and the cutting speed is obtained.
