| Abstract: | According to the structural characteristics of sheet metal parts, a practical optimized scheme for δ0.5mm ～ δ6mm sheet metal parts processing was obtained by comparison between common processing and laser cutting. The effects of different laser cutting parameters on the cutting quality were also verified. The results indicate that under the conditions of 2.4kW pulse power, 10ms pulse width, and 10^7W/cm^2 power density, better cutting quality can be obtained with high productivity, the dimension error can be controlled within the range of ±100μ m. The results show that the scheme is valid. |
