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.
