Abstract:There are different opinions on whether the tool life could be improved by the vibration drilling or not. The factors which affect the drill life during micro hole drilling were analysed, and the vibration drilling has the effective region characteristic for drill life. That is to say, the vibration drilling can extend the tool life significantly within the certain range of the hole depth (or depth-diameter ratio). The stainless micro hole drilling experiments were done, and the results showed that the life ad… Show more
