Abstract: A method for preprocessing data related to a tool electrode, which is applied in an EDM machine to manufacture a part comprises: generating an electrode model for the tool electrode based on the geometry of the part; generating the cavity shape model (volume of the part to erode), combining the electrode and cavity shape model, dividing the resulting model into a plurality of slices in a plurality of parallel planes, wherein at least one slice is composed of at least two sections, which are topologically disconnected; and generating for each slice a slice-geometry data, and generating an electrode-geometry data including the slice-geometry data.

Abstract: A method for generating cavity model applied for machining a part by electrode discharge machine (EDM) using a tool electrode comprising: a. generating a part-before EDM model defining the geometry of a part to be eroded by the EDM machine to obtain a final part; b. generating an electrode model defining the geometry of the electrode applied for eroding the part; c. computing a cavity model defining the geometrical shape of a cavity, which represent the volume of the material to be eroded by the erode based on the part-before EDM model and the electrode model.
