Technological <br />developments in the field of machining in recent years have led to many problems affecting machining <br />performance. Drilling is one of the most important machining operations. In this study effect of drilling <br />parameters such as cutting speed (15, 20 m/min), feed rate (0.1, 0.15 mm/tooth), type of drill (HSS-E, HSSE <br />TiN coated), drilling type (standard, pecking) and cooling type (liquid, air) were examined on AISI 1040 <br />steel. Parameters’ effects on surface roughness were investigated. Experiments were planned according to <br />L8 orthogonal array. Optimum conditions were found via Taguchi’s Signal/Noise analysis. Probability <br />analysis was performed to discover the distribution of the measured/calculated values of the results. <br />Lastly, confirmation tests were conducted to control the success of the optimization. The optimal <br />conditions for surface roughness were observed at A1B2C2D1E2 (i.e., cutting speed: 15m/min, feed rate: <br />0.15mm/tooth, cooling type: liquid, drilling type: standard, and type of drill: HSS-ETiN coated). <br /> </p>}, number={2}, publisher={Konya Technical University}
