STUDY WAY TO MEASURE ROUNDING RADIUS CUTTING EDGE AND ITS INFLUENCE ON THE CUTTING PROCESS

Abstract

It is known that the edge of the cutting tool as the edge on any other object, is the result of the intersection of two surfaces theoretically should be a line. The contour of this line defined the shape and mutual arrangement of the intersecting surfaces. Real is not always edge line, and in transition surface irregular geometric forms, which are more or less error is identified with a surface having a cross sectional shape of a circular arc with a certain radius of r. When finishing the processing blade prescribed minimum value serves to reduce the roughness of the machined surface. This reduces the cutting force, the build-up practically not formed decreases processing temperature and increases tool life.
