Abstract
In this paper, we discuss 3D micro-EDM with electrodes having simple shapes with a square cross-section. In order to maintain the original electrode shape, the machining conditions are set so that the bottom of the electrode is appropriately worn. The influence on the precision of the machined surface is analyzed by changing the machining parameters such as tool path and number of cutting steps. Furthermore, the formula for tool wear compensation in 3D micro-EDM is derived. As a result, square cavities with sharp corners can be machined. Inclined planes are machinable by applying the compensation equation.
