In order to investigate the influence of the shape of the mesh electrode on the electrolytic processing of GH4169 high temperature nickel-based alloy,the electrode “lifting and shaking” method was used. The comparison experiment of flat mesh electrodes with 0.5 mm,0.8 mm and 1.0 mm apertures and comparison experiment of flat mesh electrodes and and curved mesh electrodes were carried out.The results show that when the hole diameter is 0.5 mm,maching chips cannot be removed effectively,and the machining can not be continued. With the increase of the electrode hole diameter,the machining stability is improved,and with the machining speed increasing, the machining accuracy is reducing.When the curved mesh electrode is used for processing,the surface of the workpiece is uneven because the shaking plane is not parallel to the required processing surface.Therefore, in actual processing,the shape parameters of the mesh electrode should be reasonably selected according to the specific requirements,such as stability,speed and accuracy.
