Comparison of Lubrication Methods during Milling by Endmill Tool

엔드밀 공구를 이용한 밀링가공시 윤활 방법의 비교

Recently, environmental conscious machining becomes one of the most important technology in modern manufacturing industry. Especially in metal cutting, cutting fluid often results in many environmental problems. Many technologies have been developed to reduce the problems of the cutting fluid. But most of the technologies need another devices which sometimes require large space and also are very expensive, such as cooling system. In this paper, air compressor is only used to replace the functions of cutting fluid as semi-dry cutting. Cutting forces, cutting moments, and tool wear were measured to obtain cutting characteristics, and were compared with those of dry cutting and non-dry cutting. In the results of the experiments, semi-dry cutting was found to show better cutting performances than dry cutting and non-dry cutting.
