Abstract
Provided is a technology for manufacturing cutting tools that is capable of providing cutting tools that have a cut surface whose surface is uniformly smooth and that have a stable performance. Provided are a cutting tool manufacturing method in which a cutting tool material is cut by using, as a laser beam, a laser beam formed by combining two linearly polarized laser beams so that the directions of polarization of the two linearly polarized laser beams are at right angles to each other; a cutting tool manufacturing method in which a circularly polarized laser beam is used as a laser beam; a cutting tool manufacturing method in which a randomly polarized laser beam is used as a laser beam; a cutting tool manufactured by the manufacturing method; a cutting tool manufacturing apparatus that includes means for generating a combined laser beam formed of two linearly polarized laser beams, the directions of polarization of the two linearly polarized laser beams being at right angles to each other and an optical system that guides the combined laser beam to the cutting tool material; a cutting tool manufacturing apparatus that includes means for generating a circularly polarized laser beam; and a cutting tool manufacturing apparatus that includes means for generating a randomly polarized laser beam.
