Closed-Loop Process Control for Electron Beam Direct Manufacturing
ABSTRACT: Using a combination of sensing methods we shall demonstrate full closed loop computer control of the electron beam direct manufacturing processes as it relates to high deposition rate titanium. The control will vary multiple process parameters in response to direct molten pool measurements. BENEFIT: Increased material quality and reduced operator dependence and cost associated with EB-DM processing. Implementation of closed loop controls will allow full metallurgical testing to be completed under repeatabilty and controlled operating conditions.
