This paper presents the research and development of an automatic hybrid manufacturing process which based on stereo vision and laser scanning technology to produce fully dense metal parts with CNC level precision. High performance metals, such as titanium alloys, nickel superalloys, tool steel, stainless steels, etc., can benefit from this process. Coupling the additive and the subtractive processes into a single workstation, the hybrid process, can produce metal parts with accuracy. The

To achieve such a system, issues, including the modeling of the metal deposition process, the automated path planning and accurate surface scanning of the hybrid manufacturing process, are summarized.
