Cutting Performance of Cemented Carbide Using Single Crystal Diamond for Tool Material in Die and Mold Manufacturing

Article Preview

Abstract:

In this paper, the cutting performance of cemented carbide with ultrafine particles using single crystal diamond for tool material in die and mold manufacturing is investigated. The flat work is done using spiral for tool pass. The flat work is divided into small area and middle area. The spiral pitch in addition to depth of cut is changed in flat work. The tool wear is also estimated from form deviation by measuring surface form before and after machining. These results showed that ductile mode cutting was possible and the tool wear could be estimated from surface form. The tool wear was large in proportion to both the depth of cut and cutting length.
