Effect of Minimum Quantity Lubrication on Surface Roughness in Milling Machining

Abstract

This paper presents the selection of optimal technology parameters of Minimum Quantity Lubrication (MQL) method (rotation angle of nozzle to feed direction, ratio of soluble lubricant and water, distance from the nozzle spray to cutting zone) on outside end-milling machining for SKD 11 steel. The process of analyzing the effects of technological parameters is based on mathematical models, experimental models. The results obtained in this paper provide the optimal MQL parameters for end-milling machine process on steel SKD11 with reliability and effectiveness.
