METHOD OF MANUFACTURING COATED CUTTING TOOL

PROBLEM TO BE SOLVED: To provide a method of manufacturing a coated cutting tool capable of reducing crater wear, flank wear, and fritting by reducing macro particles in and on a coating to reduce the amount of pits, voids, and pores in the coating, and also capable of depositing a thick PVD coating on the tool without producing the fritting and spalling.SOLUTION: This method of manufacturing a coated cutting tool includes a step of preparing a base and a step of depositing the coating on the base by using a cathode arc evaporation PVD deposition method. The coating is a nitride, an oxide, boride, carbide, a carbonitride, a carboxynitride, or a combination thereof. In the method of manufacturing the coated cutting tool, an intermediate ion etching is applied once or more to the coating in the depositing step.
