In November 2015, the US Navy Metalworking Center released its 2015 annual report titled “Advanced Processing Solutions for Naval Systemsâ€. The Navy Metalworking Center was officially established in 1988 and is one of the Centers of Excellence for the US Naval Research Office Manufacturing Technology (ManTech), operated by an independent, non-profit application research and development professional services organization, Parallel Technologies. To support the Navy's mission and reduce costs, the Navy Metalworking Center collaborates with governments and industry to develop and optimize metalworking and manufacturing processes and implement these solutions in the US industrial base. 2015 Annual Report on Advanced Metal Processing Technology, Advanced Measurement and Detection Technology, Connection Technology, Manufacturing Process Optimization, Coating Coating and Removal, Manufacturing Tools from Project Progress, Related Results, Naval Platform for Project Implementation, Project Expected Benefits, etc. 30 key projects implemented in the six areas of development in 2015 are introduced. details as follows:
Advanced metal processing technology: Improve the processing of traditional steel alloys, high-strength steels, light alloys or corrosion-resistant metals, and integrate them into the manufacture of ships and aircraft structures, which will have a profound impact on reducing acquisition costs and total cost of ownership. The Naval Metalworking Center project developed and implemented many metalworking processes and technologies to improve the performance of naval weapon system components. In this technical field, the report lists four items such as processing 625 alloy thruster parts, aluminum alloy cracks for mitigating sensitization, 3D printing HY steel sand molds and cores, and automatic chamfering of trailing edge of turbine airfoil.
Advanced Measurement and Detection Technology: Processes and tools used to measure and inspect system components can have a significant impact on the cost and performance of naval weapon systems. The Naval Metalworking Center has led several projects that focus on improving measurement and inspection techniques and methods for complex naval systems. In this technical field, the report lists four items such as improvement of degumming detector, non-destructive testing of titanium alloy electron beam additive manufacturing, comprehensive measurement method for shipbuilding, and effective identification of board defects.
Connection technology: The Navy Metal Machining Center considers many factors in optimizing the connection method, including naval platform materials, connection types, design and manufacturing requirements, and more. The Navy Metalworking Center applies a variety of innovative welding techniques to address the challenges associated with the connection of weapon system components. In this technical field, the report lists four items: the modular and expandable cold plate for naval electronics, the welding sequence planning for the main component assembly, the profiling and welding automation, and the robot welding for complex structures.
Manufacturing Process Optimization: The Navy Metal Machining Center has a long history of collaboration with external partners and technology implementation agencies, identifying the best manufacturing processes for a given task and optimizing the process for unique applications. Technicians within the Navy Metalworking Center optimize manufacturing processes to improve quality and reduce costs, including recommendations for design changes to improve manufacturability. In this area, the report lists improvements in sonar shroud manufacturing processes, flexible facility rail systems, fuel cell manufacturability, improved weapon and ammunition C-channels, automated hanger manufacturing, degaussing system manufacturing improvements, and CVN nuclear-powered aircraft carrier vertical construction. 10 projects such as self-positioning/self-fixing construction, automated work units based on small repetitive production assembly, and improved manufacturing of reverse Brayton cycle air chillers.
Coating Coating and Removal: Optimizing coatings on naval weapon systems, including how to apply and remove them, is a major factor in improving economic endurance. Projects recently implemented by the Naval Processing Center will help improve the durability and coating methods of the surface materials of the Navy platform. In this area, the report lists two projects for progressive durability coatings and improved tile systems.
Manufacturing Tool Development: Naval Metal Machining Center's most significant technical achievements, successes, and cost reductions come from projects that develop innovative manufacturing tools and fixtures to solve naval manufacturing problems. The development capabilities of the Navy Metal Machining Center span the entire process of tool development to ensure that it meets the expected requirements and transfers the final product to a business partner or manufacturing facility. Throughout the process, the Naval Processing Center coordinated the expertise of the internal, industrial and shipyards. In this field, the report lists six items including mechanized cable towing, cable tow maintenance winch, shipbuilding additive manufacturing, hull production automation method, manned elevator sandblasting equipment, and pipe fitting production automation method.
