Research on some factors which influence the aperture of precision micro hole in electronical discharge machining

The factors which influence the size of the hole during the process of machining precision micro hole are studied in this paper. Through the way that using the same diameter of electrode wire to process large number of micro hole on different materials and different thickness, the processing time, electrode wire loss and pore size was written down. The law of the factors which influence the size of the micro hole is found by analysing the data. It can help to select the appropriate electrical processing parameters to ensure the quality of the aperture during actual operation process. And these are usually ensured by repeated testing and multiple measurements. This research get great help for improving processing efficiency. The study is of great guiding significance to the actual production.
