Abstract

In the last decades, light materials, such as aluminum, are increasing their use in wide range ‎of industrial applications. The growing use of aluminum encourages the study of its use under ‎different production processes. In this sense, the present study shows an experimental investigation in turning of aluminum, with the use of dry and minimum quantity lubrication (MQL) system. To evaluate turning process, continuous bars was used. The process is evaluated taking the surface roughness as response variable. The cutting conditions include feed rate, cutting speed and the coolant flow rate. The work-piece material and its size, the cutting tool (HSS) and the depth of cut were kept constant for the study. It has been observed that a small amount of supply of coolant at the point of cutting, largely improves the surface finish. In many cases further amount of coolant administration has very little effect on the surface quality. Thus Minimum Quantity Lubrication (MQL) can achieve the required surface quality eliminating the problems of flood cooling.
