Abstract
Laser cutting has become an extensively used method of material removal with cost effective solutions
for complex manufacturing processes. Consequently, the process has become an area of intense research
and development activity where researchers and industry experts are focusing on maximizing the
productivity and reducing the cost while maintaining a high quality. Laser cutting, as the prevalent
application of laser beam machining (LBM), offers a competitive advantage over conventional cutting
processes in terms of material savings due to narrow kerf width, less heat affected zone and minimum
distortions. The process offers high precision and good surface quality, with no tool wear and easy
automation. The current paper aims to present an overview on the recent research on laser cutting of
metallic materials, in terms of process monitoring and control as well as modeling and optimization, and
to summarize the past five years of research on the topic.
