The influence of laser cutting parameters on cutting quality of tussah by CO laser was studied, and the optimal combination of technical parameters was obtained. Orthogonal test method was used to study the influence of light intensity, feed speed and lens on seam width and seam depth, and to analyze the variation rule of main effect and interaction test data. The results showed that the main factor affecting laser cutting was lens height, and the interaction between feed speed and light intensity was significant. In actual production, the optimal combination of technical parameters can be determined according to different cutting effects required, such as laser cutting of tussah wood with water content of 6.5%, in order to obtain seam depth of about 3 000 μ m, seam width of about 200 μ m, 5 mm lens height, 40 mm/s feed speed and 40% laser intensity.
