【摘要】 根据电火花微细孔加工的特点和仿生学的蠕动原理,利用WTDS型电致伸缩位移器件驱动,研制了一个电极蠕动微进给机构,由计算机控制可实现10^-2μm级的精确进给。在此基础上可以构成一个微小电火花加工系统。更多还原

【Abstract】 Based on the peristaltic principle, this paper develops the electrode creep-micro-feeding device by using WTDS-type piezoelectric elements. This device can drive an electrode in steps of 10-2um. The feeding device can be applied to electrical discharge machining (EDM). It can machine microholes without exchanging the electrode.更多还原
