Sumario:Drilling is among the most important manufacturing processes in modern industry. Information on the dynamics of the drilling process is very important to define optimum input parameters. The minimization of burrs is a great challenge in drilling process. Current analysis was carried out with stepped solid carbide drills with straight flutes in drilling of the aluminum alloy A306. Burr height was measured at hole exits and evaluated with ANOVA technique. Results showed that the feed rate and cutting speed variation exhibited significant influence while sharpening was the most important parameter on burr formation.
