Abstract

Titanium-based alloys are difficult-to-cut materials. The conventional tool materials (HSS and cemented carbides) fail due to the high chemical affinity of titanium and high temperatures generated while machining. An attempt has been made in this work to machine Ti-6AI-4V alloy with wurtzite boron nitride (wBN) based cutting tools. The mechanisms controlling the wear of the cutting tool have been found to be similar to those observed in poly crystalline diamond (PCD) and polycrystalline cubic boron nitride (PCBN) tools. The results indicate that the wBN-cBN composite tools can be used economically to machine titanium alloys.
