Effects on Machinability of Minimum Quantity Lubrication Strategy during Milling of ST52 Steel

This study focuses on milling under sustainable cutting conditions of ST52 steel, frequently used in the manufacturing industry. steel is a good candidate as workpiece because it inexpensive and readily available. To achieve conditions, zone minimum quantity lubrication technology was during processing. The experiments three speeds (120-180-240 m min-1), feed rates (0.12-0.18-0.24 mm rev-1), constant depth cut (0.5 mm). Taguchi L9 orthogonal array to reduce repetitions. response parameters are surface roughness, flank wear, temperature. As result, when compared dry environment, environment improved roughness by approximately 62.37%, wear 9.95%, temperature 13.82%. In addition, most effective control factors were determined statistical analysis.
