Research Abstract

To decrease the impact to the global environment and realize the sustainable development of manufacturing, MQL technology, in which a small amount of bio-degradable oil is supplied with plenty of compressed air, has been widely applied to machining processes. However, it is still difficult to apply MQL technology to machining of difficult-to-machine materials effectively. In this study, MQL cutting technology effective for machining difficult-to-machine materials was investigated from theoretical and experimental viewpoints. For this purpose, MQL cutting experiment of Inconel 718 and carbon steel S45C were conducted with and without ultrasonic vibration cutting ; cutting tools for monitoring cutting temperature precisely were developed ; oil mist flow around tool tip were analyzed using a general purpose code of computational fluid dynamics. In finishing Inconel 718,optimization of the pressure of compressed air, oil consumption, and coating materials of tool increased tool life at relatively high cutting speeds of 60 m/s or more. Tools for controlling the blowing direction of oil mist COD tools were developed. It was found that these tools were able to decrease oil consumption by 50-70 percent. Application of ultrasonic vibration to MQL cutting was found to be effective particularly in decreasing crater wear at slower cutting speeds, which were inevitable in machining a slender bar of smaller diameters. With tools for monitoring cutting temperature precisely, thin film thermocouples were fabricated on the tools using photolithography technology, then were coated with hard and thin TiN film. Cutting temperature in turning was measured with these tools. The flow of oil mist was analyzed for tuning and grooving. In grooving, reduction of oil consumption was related to the localization of the flow of oil mist quantitatively.
