Burr height model for vibration assisted drilling of aluminum 6061-T6

Vibration assistance has seen increasing application in metal removal processes. One application of this technique is vibration assisted drilling. This method typically induces high-frequency and low-amplitude vibration in the direction of drill feed during drilling, and has the potential to reduce thrust forces and reduce exit burr height. Note that this cutting process is distinct from ultrasonic machining/drilling. Predicting exit burr …
