Abstract:
A method for manufacturing a finished blade of a cutting tool, having a cutting edge, comprising:(a) treating a blade base material with a laser in a first process step along a curve contour determined by said cutting edge of said finished blade to form a laser treated area and, in a second process step, forming the blade base material to a desired shape with said cutting edge inside said laser-treated area, or (b) machining said blade base material in a first process step by punching or trimming the blade base material to a desired shape having said cutting edge, subsequently in a second process step, laser treating the cutting edge of the finished blade, and in a third process step, shaping the laser treated cutting edge, whereby the laser treatment is by laser beam dispersion or laser beam alloying and whereby the laser beam dispersion or laser beam alloying is carried out with a material selected from the group consisting of chromium, tungsten, molybdenum, titanium, vanadium, tantalum, nickel, cobalt, manganese, and combinations thereof.
