Effect of Minimum Quantity Lubrication in Machining Using Different Vegetable Oils

Abstract

In metal industries and researchers are trying to reduce the use of coolant lubricant fluid in metal cutting to give the better performance, health safety, economic benefits and reduction in environmental pollution. Lubrication is necessary for the cutting operations to avoid the surface damages. The MQL gives better result over the conventional flood cooling as it effectively reduce the tool wear through mixture of air and lubricant and also impairs the surface finish of product. The minimization of cutting fluid leads to saving the lubrication cost and also saves machine cleaning time. This study deals with experimental investigation on role of different vegetable oils tool wear and surface finish. Experiments were carried out by plain turning of round bar of SAE 1018. The aerosol based on different vegetable oils was used to evaluate the tool performance and surface finish at different speed combinations. It was observed that Aerosol consist of Canola oil gives less tool wear and comparative surface finish as compared to Sunflower and Soybean oil. SEM results also analyzed in terms of tool wear.
