Combinatorial Optimization of Reasonable Technical Parameters for Laser Cutting Oak

[Objective ] Aiming at cutting oak by laser,the influences of single and multiple cutting technology parameters on cutting seam width and depth were investigated,in order to provide theoretical basis to quickly determine the reasonable technical parameters according to the cutting effect requirements for production processing professionals.[Method]The technical parameters of laser cutting machine were used as influence factors,and the depth and width of cutting seam were set as the target of cutting effect.The longitudinal and horizontal comparison method were applied to observe the regularity of data change and proceed experimental data handling.[Result] The results showed that,in the case of single cutting,when lens height was F = 3 mm,the seam width was about 0.2 mm; if F = 7 mm,the width was about 0.1 mm; if F = 11 mm,the width was about 0.3 mm.In the case of secondary cutting,if F = 3 mm,the width was about 0.2-0.3 mm; if F = 7 mm,the width was about 0.1-0.2 mm; if F = 11 mm,the width was about 0.3-0.4 m
