Abstract
A cutting tool is fixed to a cutting tool holder in such a manner that the posture of the cutting tool can be adjusted without being removed from a processing machine. The cutting tool holder is fixed to a fixing base to allow the cutting tool holder to be fixed in the same position thereof repeatedly with high reproducibility. After the flank of the cutting edge of the cutting tool is measured by an objective interference microscope, the posture of the cutting tool with respect to the cutting tool holder is adjusted so that an interference fringe coincides with a predetermined interference fringe.
