MQL 선삭가공시 가공물의 원통도 평가에 관한 연구

At present, industries and researchers are looking for ways to reduce the use of lubricants because of ecological and economical reasons. Therefore, metal cutting is to move toward dry cutting or semi-dry cutting. This paper presents an investigation into MQL(Minimum Quantity Lubrication) machining with the objective of evaluating the cylindricity for the turning process of SM45C. To reach this goal, several cylindrical-outer-diameter turning experiments are carried out by fluid cutting, MQL cutting and dry cutting. Also, the temperature of the tool-shank and cylindricity of workpiece are measured. It is found from the results of experiments that the cylindricity in MQL cutting is better than the others.
