Recent Progress on the Efficiency Increasing Methods of Minimum Quantity Lubrication Technology in Green Cutting

Abstract

As a green and efficient processing method, minimum quantity lubrication (MQL) has the advantages of small amount of cutting fluid using, low cutting force, preventing adhesion, prolonging tool life and improving the surface quality of workpiece. However, there are some problems such as inadequate lubrication and low cooling performance under the specific conditions. Therefore, experts have proposed several kinds of minimum quantity lubrication synergistic technology. The latest research progress in the principle is summarized, implementation scheme and process application of minimum quantity lubrication synergistic technology. The purpose is to extend the application scope of minimum quantity lubrication technology and provide theoretical support and scientific guidance for further research on minimum quantity lubrication synergistic technology.
