There is consensus among both the research and industrial communities, and even the general public, that additive manufacturing (AM) processes capable o f processing metal lic materials are a set o f game changing technologies that offer unique capabilities with tremendous application potential that cannot be matched by traditional manufacturing technologies. Unfortunately, with all what AM has to offer, the quality and repeatability o f metal parts still hamper significantly their widespread as viable manufacturing proc esses. This is particularly true in industrial sectors with stringent requirements on part quality such as the aerospace and healthcare sectors. One approach to overcome this challenge that has recently been receiving increasing attention is process monitoring and real-time process control to enhance part quality and repeatability. This has been addressed by numerous research efforts in the past decade and continues to be identified as a high priority research goal. In this review paper, we fill an important gap in the liter ature represented by the absence o f one single source that comprehensively describes what has been achieved and provides insight on what still needs to be achieved in the field o f process monitoring and control fo r metal-based AM processes.

Fibre laser metal deposition with wire: parameters study and temperature monitoring system

et al. 2008

View full text Add to dashboard Cite

This paper addresses the development of a laser metal deposition process which consists of a 2 kW Fibre Laser, a CNC table, a wire feeder and a temperature monitoring system. During its development, six infrared pyrometers were tried to compare their performance. The system utilizes two pyrometers to measure both the melt-pool and workpiece (upper layer) temperatures. Experiments have been performed to study the metal deposition parameters with stainless steel 308L wire deposited on stainless steel 304, and good quality metal deposition has been achieved. The results of the parameters study and the development of the temperature monitoring system are presented.
