Recently developed of pulsed fibre laser marking system is becoming a powerful tool for precision cutting and drilling. It can provide dimensional cut repeatability to sub 10 microns, cut or drill material up to 0.5mm with minimal to no burring, and offer multi axis motion options. The material removal mechanism of the new process in relation to pulse parameters is described, along with examples of high quality cutting and drilling results on flat sheet/tubes in ferrous and highly reflective metals. Effective cutting speed and minimum kerf width are compared at different thickness for stainless steel, copper and aluminum. Open slot cutting and drilling are also demonstrated on Platinum-Iridium tubes.
