| Research Abstract |
In order to reduce anti-environmental materials emitted during machining, the development of machining technology with the minimum quantity lubrication is urgent. However, no method has been established for evaluating the minimum quantity of cutting oil carried with compressed air that cools down the cutting tool and workpiece well enough in cutting area. Therefore, the objectives of this project are analyzes for evaluating the cooling efficiency and supply conditions of the minimum quantity lubrication, and the development of tools with thin film thermal sensor for monitoring the performance of the mist of cutting oil.
First, the cooling efficiency of end mill under various cooling conditions has analyzed, such as in dry cutting, air cooling cutting, water cooling cutting, cutting with high pressure coolant, and MQL cutting. Through the analysis, the cooling efficiency of MQL was compared with that under other cooling conditions in the wide range of cutting speed, feed rate and coolant velocity. Secondly, the flow of the mist of cutting oil under the tool clearance face was analyzed under the various conditions of cutting speed and air mist velocity, and the rate of the mist of cutting oil supplied to the area around the cutting edge was evaluated. Thirdly, tools with thin film thermal sensor for condition monitoring was developed using the surface coating technologies. Finally, finite element modeling for analyzing ultra-high speed cutting was developed and it was found that the maximum temperature reduced with cutting speed in the range of ultra-high speed cutting.
