A method for manufacturing a steel tire mold that uses CAD and CAM software to design the shapes of the mold and develop numerical sequences for computer numerical controlled (CNC) machines, electrodes for an electric discharge machine (EDM) and characters and designs on the tire, and the CNC lathe forms the different designed parts. Alignment and assembly holes are bored so the parts can be assembled to form a semi-finished mold. The tread design is formed in the electrode by the CNC machine, and the electrode is used with an electric discharge machine to cut the tread design in the mold. The CNC engraving machine cuts the characters and designs in the mold. Finally, the mold is dressed to remove any burrs, and the mold is a finished product.
