Abstract

To solve the actual production problem that micro drill easily prone to break during micro drilling process, the process for drilling micro hole of 0.08 mm on the 316L stainless steel was conducted and the main factors are analyzed, which demonstrate that the excessive torque is the main reason for breaking of micro drill. Therefore, the regression analysis for the drilling force under different drilling parameters is analyzed and the empirical formula of the drilling force is obtained. Meanwhile, the significance and the accuracy are also analyzed. According to the obtained empirical formula, the optimum drilling parameters during drilling process of stainless steel is established, and its validation is further confirmed in the actual production process.
