Optimization of Sanding Parameters for Surface of Pyinkado Plates

In order to analyze the relation between surface roughness of Pyinkado plates and sanding parameters, an orthogonal experiment and a single factor experiment were performed. The results show that the mesh of the sandpaper has remarkable influence on surface roughness of Pyinkado plates, but the feeding speed and sanding thickness don't; when the mesh of the sandpaper is 150, the feeding speed is 6 m/min and sanding thickness is 0.4 mm during the first sanding and the mesh of the sandpaper is 240, the feeding speed is 9m/min and sanding thickness is 0.15mm during the second sanding, the smallest roughness (Ra) was obtained as 2.81 mu m. Considering production efficiency, changing feeding speed into 9 m/min in the theory optimization scheme, engineering optimization scheme was obtained, and the wood surface roughness (Ra) is 2.91 mu m.
