微细电火花加工中的电极在线制作与检测

Fabricating and measuring the micro-electrode on-line in Micro -EDM

将反拷块与线电极电火花磨削 (WEDG)装置相结合 ,成功地实现了微细电极的高效、高精度在线制作。充分利用机床的数控功能和接触感知功能以及标准量块和WEDG装置 ,在不增加任何测量附件的情况下 ,实现了微细电极的锥度及尺寸测量。

This paper raise a new method to fabricate the micro electrode on line with efficiency and high precision by combining the reverse copying block unit and WEDG unit together.By make full use of the NC function and the apperceive function of EDM machine tool,with the aid of the standard masuring block and the WEDG unit,the taper and the diameter of the micro electrode can be measuerd easily.
