Abstract:
In order to machine micro aspheric molds made of ceramics, micro milling tools made of single crystalline diamond (SCD) are developed. Many cutting edges are fabricated 3-dimensionally on the edge of a cylindrical SCD by a laser beam. Flat shape of tungsten carbide was cut with the developed tool to evaluate the tool wear rate and its life. Some micro aspheric molds of tungsten carbide were cut with the tool at a rotational speed of 50,000 min-1. The molds were cut in the ductile mode. The form accuracy obtained was about 100 nm P-V and the surface roughness 10 nm Rz.
