Development of an ultra-precision milling and grinding tool (1st report)

Abstract

The purpose of this research is to develop a next generation manufacturing process having both advantages of ultra-precision milling and grinding. In the manufacturing process, various three dimensional machining technologies are necessary to produce the cutting tool which features eight rotating monocrystalline diamond blades. Technologies are applied to fabricate edges, ridges, radius of the tips and height differences of the blades, within 10nm accuracy. Usually, two sets of cast iron plate are necessary for on-machine shaping of the blades. However, this time a fabrication technology using a double-face-incline cast iron plate has been developed. In the paper, principle and results of the new fabrication technology will be reported.
