• Laser-Forming Technique of Single-Point Cutting Tool Made of Nano-Polycrystalline Diamond

抄録

A laser forming technique adaptable to producing a single-point cutting tool made of nano-polycrystalline diamond (NPD) with a nose radius of 0.4 mm and a sharp cutting edge was developed. Both the chipping and wear resistance of tools made of NPD and single-crystal diamond (SCD) produced using the laser forming technique were compared by applying both tools to the face turning of cemented carbide with a hardness of 1450 Hv. A forming test was conducted on an NPD chip soldered on a substrate made of cemented carbide. It was verified through the forming test that a sharp cutting edge with a roundness of less than 1.0 μm could be formed by rotating the NPD rake face to the negative Z direction of the machining center and moving the laser beam on the inclined path from the substrate to the NPD rake face when forming the flank face. In addition, a cutting test revealed that the wear volume of the NPD flank face at a total cutting length of 4 km was 23% of the value measured from the SCD flank face.
