Abstract

Vibration Drilling (VD) is one of the advance machining techniques to produce precision holes. In this study the vibration tool of drilling process is made with a new design while drilling tool vibrates by an ultrasonic transducer, it also rotates. The exerted vibration to tool has frequency of 20.6 kHz and low peak-to-peak amplitude. After preparation of process set-up, primary experiments were done on Al2024 workpiece. In these experiments , it was shown that thrust force in vibration drilling process is lower than in ordinary drilling (OD).Then the influence of some machining parameters include cutting speed and feed rate on thrust force in VD process studied and compared with OD process.
