摘要
本文提出了一种在线制作微型工具电极的新方法。该方法是基于电化学微加工,通过反复交换工具电极和工件的极性,进行相互加工获得与电化学微加工相适应的微型工具电极。由于该过程在线进行,因此可以避免因两次夹紧工具电极造成的位置误差和夹紧误差,并可以大大提高加工精度。该方法对于电化学展成微加工来说是非常重要的。通过实验,稳定的加工出了最小直径为20μm的工具电极。
mechanism In this paper a new method for on-line fabrication of micro tool-electrodes based on the machining of electrochemical micromachining is put forward. By exchanging the polarities of the tool-electrodes and appropriate for electrochemical mieromachining can be obtained through mutual machining. Because the processes are carried on-line, the position error and clamp error caused by twice-clamp of tool-electrodes can be avoided and the machining precision can be improved greatly. This method will be very important to electrochemical generating micromachining .Experiments are conducted and a tool-electrode with the pinpoint of 20μ m is obtained stably.
