We are conducting research and development using AM equipment to improve the efficiency of the manufacturing process for turbine nozzles, which require preparation such as casting or mold carving and discharge. We are verifying the feasibility of a technology that has the potential to reduce material costs and enable more flexible part design. In addition, we have begun to develop applications for AM technology to optimize the hardness and tooth surface strength of gear components. AeroEdge is accumulating basic research data in order to implement VE/VA proposals aimed at broadening the scope of design and creating higher value-added parts. We are convinced that if we can automate labor-intensive work using AM technology by conducting AM technology verification as an alternative process to welding, it will lead to increased cost competitiveness, and we are implementing everything from conceptual design to prototyping with a view to applying the technology to mass production of turbine blades.
