| Research Abstract |
Regarding high-performance near-dry machining which can considerably decrease the amount of cutting fluids and is therefore environmentally friendly, its tribological behavior was investigated in detail. As a result, in machining of aluminum alloys necessitating the high lubricating effects of fluids, it was found that some of such chemical compounds including oxygen as esters, alcohols and acids had the excellent cutting performance and that coexisting water could improve the performance. Further, in near-dry machining of a stainless steel which is one of difficult-to-cut materials, hybrid mist supply of an ester and a water-based coolant demonstrated to be effective in providing the higher cutting performance.
