To solve the electrode wear problem in three-dimensional micro-electrical discharge machining (3D micro-EDM), a new compensation method of combination of linear compensation method (LCM) with uniform wear method (UWM) is presented. The experimental results show that the machining efficiency and the roughness on the bottom surface are improved obviously in 3D micro- EDM, and the electrode wear is reduced using this new method. Compared with the UWM, the length of electrode wear decreases by 17.8%, the surface roughness reduces by 9.9% and the material removal rate increases by 10. 1%. [ABSTRACT FROM AUTHOR]
