In accordance with the principles of the cutting phenomenon, following utilizing computational science, we developed an excellent-machinability additive which dramatically improves the machinability of sintered components. We have demonstrated that the developed excellent-machinability additive can reduce the tool wear in each corresponding tool dramatically to 1/6 to 1/12 in outer periphery machining processes assuming outer diameter processing, undercut grooving and so forth, using a cermet, K grade carbide and CBN tools, which are popularly used in machining of sintered parts. This article reports on the details about the above study.
