| Outline of Final Research Achievements |
For machining of aluminum alloys, by using a polyol ester in combination with alcohols as a lubricant, this study presented an optimal near-dry machining system mounting a minimal quantity lubrication (MQL) mist generator with a humidifier. Regarding machining of titanium alloys, on the other hand, this study evaluated the practical cutting performance in the cases of four methods, that is, MQL machining, coolant mist (CM) machining which could supply water soluble coolant, hybrid mist (HM) machining which could supply combined mists of MQL oil and coolant, and conventional wet machining. The evaluation results demonstrated CM machining, compared with wet machining, considerably elongated the tool life and thus this study proposed CM machining as an optimal near-dry machining system for such difficult-to-cut material as titanium alloys.
