Abstract

High-quality wood products and valuable wood crafts receive everyone’s favor with the rapid development of the economy. In order to improve the cutting surface quality of wood forming parts, the cutting experiment of renewable Fraxinus mandshurica was conducted by waterjet-assisted CO₂ laser (WACL) technology. A quadratic mathematical model for describing the relationship between surface roughness changes and cutting parameters was established. The effects of cutting speed, flow pressure and laser power on the kerf surface roughness of Fraxinus mandshurica when cutting transversally were discussed by response surface method. The experimental results showed that kerf surface roughness decreased under a lower laser power, higher cutting speed and higher flow pressure. When the cutting speed was 30 mm/s, flow pressure was 1.58 MPa and laser power was 45 W, the actual surface roughness of the optimized Fraxinus mandshurica was 2.41 μm, and it was in accord with the theoretically predicted surface roughness value of 2.54 μm, so the model fitted the actual situation well. Through the analysis of 3D profile morphology and micromorphology, it was concluded that the optimized kerf surface of Fraxinus mandshurica was smoother, the cell wall was not destroyed and the tracheid was clear. It provides the theoretical basis for wood micromachining.
