CUTTING BLADE IDENTIFYING METHOD AND PROCESSING APPARATUS

An object of the present invention is to be able to identify blade information of a cutting blade. An identification method of a cutting blade comprises: a blade management step of associating an image of the surface of a cutting edge of the cutting blade with blade information of the cutting blade and registering the same as management data in a blade management unit; an imaging step of imaging the surface of the cutting edge of the cutting blade whose blade information is to be confirmed; and a blade information confirmation step of finding an image of the surface of the cutting edge that matches the image captured in the imaging step from management data registered in the blade management unit, and confirming blade information related to the image of the surface of the matching cutting edge.
