| Abstract: | This paper analyses the special dynamic behavior of entering drilling of micro drill with vibration in the direction of axis and its correction function to location error of entering drilling.This experiment has used a new machining method-varying amplitude in vibration drilling.In the experiment a kind of low carbon alloy structure steel 18Cr2Ni4WA has been drilled with a host drillwhose diameter is 0.28mm.The life of the drill and the location accuracy of entering drilling of microvoid are remarkably improved. |
