Abstract
To solve the troubles due to burrs formed in cutting process, it is important to understand formation mechanism of the burrs and to classify those. In the previous paper, formation mechanism of the exit burrs formed at edge of exit and machined surfaces in milling was analyzed and a classification method for the exit burrs was proposed. In milling process, however, not only exit burrs, but also other kinds of various burrs are formed on various edges located on a workpiece. In the case of cutting a rectangular parallelepiped workpiece in face milling operation, five kinds of burrs are observed as follows: (1) exit burr, (2) side burr, (3) top burr, (4) entrance burr and (5) entrance side burr. In this study, formation mechanism of the various burrs except exit burr, such as side burr, top burr, entrance burr and entrance side burr are, analyzed. These burrs have similarity and difference with exit burr in the formation mechanism each other. Therefore, the similarity and difference with exit burrs in the burr formation mechanism are explained in the proposed classification. Moreover, those burrs are classified applying the classification method proposed in the previous study.
