中文摘要：
在轴向振动钻削过程中,各切削参数的变化对钻头的工作角度会产生很大影响.由于刀具是断续切削的,所以首先求解切削的起终点,进而计算在切削时段内刀具的工作前后角,结合金属切削理论,分析加工参数的合理性,给出了振动钻削参数选择的理论依据.
英文摘要：
Operation angles of a drill are influenced by variation of parameters of the axial vibration drilling. As the tool is cutting intermittently, the start and end points are first determined. The working rank angle and back angle of the tool during cutting are calculated. Using the metal cutting theory, cutting parameters are analyzed, and parameters of vibrating drill given. This opens a new way for studying the mechanism of vibrating drill and selecting parameters.
