Abstract

See full text

A method of forming a scribe line on a work surface is carried out by a scribing apparatus comprising a scribe body including an abutment member, such as cutter provided with an penetrator, having at least first and second ridgelines and a sharp tip end portion and a vibration generating member for periodically applying vibrations to the abutment member. A vibration is applied to the abutment member with the tip end portion thereof abutting against the work surface, and the scribe body is relatively moved along the work surface to thereby form a scribe line on the work surface. In this scribing method, a first angle constituted by the first ridgeline of the abutment member and the work surface and a second angle constituted by the second ridgeline thereof and the work surface are made different from each other and the first and second ridgelines are opposed in the moving direction of the scribe body.
