Abstract
Tool electrodes for and methods of electrical discharge machining are provided. In one exemplary aspect, a tool electrode for machining features into a workpiece is provided that allows for increased machining speed without sacrificing the quality of the machined features. Moreover, a tool electrode is provided that eliminates or reduces the high cost associated with customized tool electrodes. In particular, a tool electrode is provided that includes a plurality of electrode elements arranged and spaced apart in a digitized matrix representative of a tooling shape for machining features into a workpiece. The plurality of electrode elements are spaced apart from one another and arranged in the digitized matrix by digitizing an analog electrode tool configured to machine the feature into the workpiece or a volume of the feature to be machined into the workpiece.
