When traditional machining methods reach their limit, electric discharge machining (EDM) can be the answer. The EDM process allows for high accuracy and is applicable for any conductive material.
Electric discharge machining, or EDM, is a non-traditional method in which material is removed from a workpiece using thermal energy. Much like processes such as laser cutting, EDM does not need mechanical force in the removal process. This is the reason why it is considered non-traditional contrary to, for example, the processing with cutting tools.
In tool and mold making, EDM is very popular due to its applicability especially for hard materials like titanium or for particularly complex shapes that are hard to achieve with milling.
