Abstract: Four promising laser assisted manufacturing approaches are
introduced, including die-less laser forming, laser shock processing,
laser micro-machining, and laser based direct metal deposition. The
chief working principal, modeling methods, influencing factors, and
metrology means are investigated to reveal the fundamental focus. The
potentiality in forming of low-volume and high-variety sheet metal and
tube components of high-strength material is revealed, together with the
rapid prototyping of metal components. The enhancement of surface
strength of curved utility shows strong possibility with laser shock
processing, while micro-machining with ultra-short pulsed laser supply
efficient tools for various materials.
Key words: Die-less laser forming Laser shock processing Laser
micro-machining Mechanism Influencing factors
