| Abstract Scope |
Robotic forming is a process where a metallic alloy is sequentially and locally deformed to incrementally change the shape and material properties from an initial state to a goal state. This process enables both part complexity and part customizability, whilst maintaining the fine-grained microstructures inherent to hot and cold forging processes. Autonomous control of the incremental forming process is a formidable challenge. Most current robotic forming is an open-loop process, with the exception of a few examples of incremental sheet forming. The field of control systems has a mature suite of techniques that enable robotic forming control. This paper proposes a general formulation of robotic forming processes as a state-space dynamic system that facilitates the application of the established techniques. Based on this formulation, we study the incremental plate forming process as a case study to demonstrate control formulation, controllability and observability analysis, and control design synthesis. |
