In this paper, an experimental investigation will be done on the influence of main drilling parameters on burr formation in machining low carbon steel and stainless steel by using HSS cutting tools and cutting fluid. Particular attention will be focused on the relation between the burr sizes with drilling parameters. Therefore, a wide range of cutting speeds and feed rates will be investigated to explore the optimum drilling conditions. Burr heights will be measured and analyzed at different drilling conditions to determine the effect of drilling speed and feed rate on burr formation. The data obtained for low carbon steel will be compared with those for stainless steel. Different diameters of HSS twist drill will be used to observe their effects on drilling burr formation. The quantitative measurements of burr heights and size are investigated under these conditions.
