Process Control for Robot Based Additive Manufacturing

Abstract

In this paper a new control system for robot based additive manufacturing is presented. The paper summarizes the results of an ongoing major joint project being completed by industrial companies and research organizations. The objective is to increase the process stability and the part quality of parts produced by laser metal deposition through controlling the distance between nozzle and part surface. In particular, the system architecture, the control method and the first test results are presented.
