| Summary: | Nowadays, carbon fiber reinforced plastics (CFRP) composites is widely used in the
aerospace industry due to its excellent mechanical properties. In laser cutting process, high powers
are used to cut materials then material melts and burns leaving edges with a high quality finish. To
fulfill the high demand of cutting quality, a set of laser cutting parameters of CFRP material are
studied. The objective of this experiment is to obtain an optimum laser cutting parameter thus
minimizing the cutting defects particularly on kerf width at the top and bottom surfaces. The
analysis of process parameter was carried out using DOE, Design Expert 6.0.8. Cutting speed, pulse
duration, pulse repetition rate and pulse energy were analyzed at two levels. By the optimizing the
parameter setting, significant improvement in cutting quality has been achieved. |
