Abstract: Hybrid Autonomous Manufacturing, Metamorphic Manufacturing, and Robotic Blacksmithing refer to the numerically controlled agile deformation processing of deformable materials with intended control of both component configuration and local materials microstructure and properties. This can be carried out by the integration of:
• Sensors - to monitor shape, temperature and measure or infer other variables,
• Thermal control -- induction, flame, lasers or other to provide local temperature
• Actuators for deformation -- this may be a press, but rollers, impact or other means are possible,
• Robotics for positional control
• Computation -- to infer local states and possibly decide on next process steps.
In principle a very large number of high-quality components can be created in this way and the system could become truly autonomous. This is a core subject for a relatively new center at Ohio State University: the National Science Foundation's HAMMER, Engineering Research Center -- Hybrid Autonomous Manufacturing - Moving from Evolution to Revolution. This presentation will summarize recent progress in approaching the goals of shape, microstructure and autonomous systems and also discuss current research efforts an open problems in related areas of machine learning, uncertainty quantification, data analytics, and certification and qualification from a microstructural point of view.
Speaker Bio: Stephen Niezgoda is an associate professor in the Departments of Materials Science & Engineering and Mechanical & Aerospace Engineering at The Ohio State University. He is the associate director or the NSF Funded Engineering Research Center Hybrid Autonomous Manufacturing: Moving from Evolution to Revolution (HAMMER). Prior to his engineering studies Niezgoda worked as an industrial mechanic and machinist, and as an F.A.A. certified aircraft mechanic (A&P ratings). He obtained his Ph.D. from Drexel University in 2010 where his research was focused on microstructure sensitive design. For his thesis work, he received the Drexel Thesis Award “Most Promise to Enhance Drexel’s Reputation in the Mathematical and Physical Science.” Niezgoda then went on to postdoctoral research appointments at Los Alamos National Laboratory in the Materials Science in Radiation and Dynamic Extremes group and at the Lujan Neutron Scattering Center (LANSCE). Niezgoda is the leader of Micro- & Mesoscale Mechanics and Structures Laboratory at The Ohio State University. His research covers a broad area including: crystal plasticity and theoretical mechanics, materials data analytics, advanced manufacturing, and machine learning.
