Ultrapresicion cutting of tungsten carbide mold by micro milling tool (3nd report)

Tool Wear Evaluation

Abstract

Micro milling tools made of diamond were developed in order to machine ultraprecision aspheric mold of tungsten carbide precisely. In this report, micro milling tools made of single crystal daiamond and CVD diamond were fabricated and the changes of the tool wear, the form accuracy and the surface roughness were compared with the PCD tool and the resinoid bonded diamond wheel.
