Laser drilling is the nontraditional machining methods that provides the machining of sheet metal parts with high precision and complex geometry. In laser drilling, the main parameters such as the focal point, gas pressure and feed rate directly affecting the cutting process play important role on the quality characteristics of the part. These parameters significantly influence the main machining outputs or responses such as burr formation and hole quality as well as the machining productivity. Thus, it is important to determine the ideal machining parameters during laser drilling, especially in terms of minimum burr formation. In this study, burr formation during laser drilling of ferritic stainless steel was analyzed in detail and mathematical model of burr height (Bh) was developed. Drilling operations were performed at three different focal point, gas pressure and feed rate. According to the experimental results, the smallest Bh value was obtained with focal point of -5, feed rate of 1200 mm/min and gas pressure of 12 bar. Based on analysis of variance, the most important parameter for burr height was found as the feed speed with 38.71%. The cutting parameters, statistically, were evaluated for the burr height. The R2 value of Bh model obtained by response surface method indicated a robust relationship in high level between the machining parameters and response.
