In connection with the worldwide increase of the environmental consciousness, eco-machining becomes one of the most important subjects in the mechanical production field. Consequently, MQL (Minimal Quantity Lubrication) machining process becomes the practical technology today. However, behavior of the mist particle at the tool-work interface in company with its lubrication and cooling effect in that interface has not been made clear. Indeed, although it is indicated that the mist particles floating in the surrounding are so small that the machining operator can be damaged by the particle, even the density of the mist at the arbitrary point can not be known. In this study, authors tried to develop a simple and small mist density sensing system by means of QCM (Quartz Crystal Microbalance) sensor conventionally used for the smell sensor. The developed system was evaluated by some experiments to check its sensitivity and reliability in the view point of the availability for the practical use. As a result, it was shown that the density of oil mist can be qualitatively obtained by measuring the resonance frequency of the circuit, and that this system is applicable to the actual production fields.
