In the paper, a novel technique beam shaper used in optical path is developed to cut cover layer which can reduce charring obviously. The effects of process parameters, ventilation systems, lasers and materials on charring were researched in laser cut cover layer. Studies have shown that cutting at high speed, high laser frequency and low power can achieve high quality cutting with little charring. It was also found that improved ventilation systems, different lasers and materials can reduce charring. The developed process offered theoretical and experimental basis for practical application.
