| Abstract |
When cutting titanium alloy, the temperature of a cutting tool edge is easy to rise and the
tool edge is tend to be worn away quickly because the titanium alloy has the characteristics of low
thermal conductivity and high chemical activity. Therefore, it is difficult to achieve a balance between
the productivity and the tool life in cutting the titanium alloy, namely, low-speed cutting must be
carried out at present. To examine the possibility of the improvement in the cutting efficiency, a PCD
(polycrystalline diamond) tool having high thermal conductivity was adopted to the cutting of
titanium alloy and its cutting performance was investigated. The PCD tool was found to have
excellent flank wear resistance compared with conventional cemented carbide tools. It was also
revealed that unprecedented high speed cutting become possible by use of PCD tool with an
application of high pressure coolant. |
