Abstract
This study describes the influence of BN coating conditions on cutting performance. cBN sintered tool has good cutting performance. But this tool is extremely expensive and has configuration limitation. If carbide end-mill could be coated with c-BN; so that superior end-mill can be produced cheaply. In this paper, the better BN coating conditions that is suitable for SUS304 cutting were discussed on basis of experimental results, for example tool life, cutting force and observation of tool damage.
