Experimental Research on Overspeed Wear Mechanism of the Flank Face of Twist Drill in Peripheral Vibration Drilling
The peripheral vibration drilling is a new type of hole processing,the twist drill is an important tool to realize this kind of processing,the overspeed wear of the flank of twist drill is an important factor restricting the hole quality of the peripheral vibra-tion drilling and drill life.Based on sampling experiment and orthogonal experiment,the causes of overspeed wear failure of the flank of high-speed steel twist drill are analyzed comprehensively in this paper,the relationship between the wear of the flank of twist drill and machine tool parameters and the process parameters as been discussed.The key factors of the overspeed wear of twist drill flank were studied by the orthogonal Contrast experiments on the peripheral vibration drilling machine.The results show The parameters of the machine tool itself and the processing parameters have an effect on the excessive wear of the twist drill flank.The parameters of the machine tool are mainly the radian and circular frequency of the shimmy;the process parameters are mainly longitudinal feed and drilling speed.
