Coordinate system setting for post-machining of impeller shape by wire arc DED and evaluation of processing efficiency

Abstract Wire arc additive manufacturing (WAAM) is a direct energy deposition (DED) process that uses arc welding.It is a method of stacking beads made by melting metal wires with an arc heat source generated by a short-circuit current.Compared to other metal additive manufacturing methods, this process can be used to quickly produce large and comp
