【摘要】 应用压电陶瓷振动台振动钻削装置,采用变进给量振动钻削法加工微小孔,并用工具显微镜对入钻定位误差和出口毛刺进行测量。采用最小二乘法对所得试验数据进行处理,从而得到进给量与出口毛刺之间的关系,通过对两种条件下(变进给量振动钻削和普通钻削)所得试验数据的比较可知,变进给量振动钻削能使加工质量得到很大提高。更多还原

【Abstract】 By applying apparatus for piezoelectric ceramic vibration drilling, the me thod of varying feed rates in vibration drilling is used to drill the micro-hol e . The orientation errors at the beginning of process and residue stabs at the en d of the hole are measured with tool microscope. Least square method is used for processing the test data to get correlation between feed rate and residue stabs . The conclusion is that machining quality is improved by varying feed rate vibr ation drilling.更多还原
