Sažetak
The process of deep hole micro-drilling is characterized with a higher depth to diameter ratio that leads to difficult evacuation of the chip from the hole and increased friction between the tool and the workpiece. This causes an increase of drill wear, drilling forces and torque. In combination with the small stiffness of the drill could often lead to the tool breakage, less productivity and sometimes to the loss of the workpiece. One option to increase the reliability of the process is superimposing vibrations to the standard kinematics of the drilling process. Preliminary experimental investigations on vibration assisted deep-hole micro-drilling of AlMg3 material, with hole aspect ratio of 1:20, are performed. Drill lifetime related with drill breakage is compared between vibration assisted and conventional micro drilling process.
