Abstract
A method and apparatus for cutting a hard and brittle material using a system for applying vibration in two directions with a strip-shaped flat cutting tool. The material to be cut is caused to make a reciprocating motion of a given stroke length together with a first small-amplitude, low frequency vibration in directions parallel to the reciprocating motion. Concurrently with this, a second small-amplitude vibration is applied also to the material to be cut in directions parallel to the cutting direction of the cutting tool into the material and in synchronism with the first small-amplitude vibration. Meanwhile, cutting pressure is applied to the cutting tool to a desired degree with a cutting fluid containing abrasive grain supplied to the cutting part of the material during the process of cutting.
