Abstract (en)

[origin: WO0170450A1] A method for manufacturing a near net-shape mold from a weldable material, including creating a computer model of a mold portion (30, 32), analytically sectioning the computer model of the mold portion into a plurality of mold zones (22), generating mold zone cutting paths for a cutting machine to follow, cutting the weldable material into plurality of mold zones, generating surface profile cutting paths for a cutting machine to follow, machining surface profiles into the mold zones, assembling the mold zones by placing the mold zones side-by-side, generating welding paths for an electron beam welding a machine to follow, and welding the mold zones together.
