Abstract

To fabricate near net-shape nickel alloy turbine blade airfoil with complex internal structure, process of laser net shape manufacturing (LNSM) is studied in two aspects. One is steady process analysis to establish transfer functions between dimension and process parameters. Another one is dynamic process analysis focusing on decreasing defects in the region of special geometry features. Two solutions, path planning with process parameters optimization and vision based closed-loop control are implemented to keep the process stable in those areas. Both solutions are applied successfully in nickel alloy turbine blade airfoil deposition with LNSM system. Geometric inspection shows good dimensional accuracy and surface quality can be achieved with this technology.
