【 摘 要 】

3D surface roughness of milled aluminium surface was evaluated using the laser speckle pattern. The milled surface was produced from aluminium alloy Al 6061 material at ten different feed rates using CNC milling machine. Laser beam was directed onto the aluminium surface and the scattered beam from the surface of the sample underwent interference to produce laser speckle pattern. Coefficient of Determination between various characteristic features and 3D surface roughness were determined and it was found that 3D surface roughness parameter Sv have coefficient determination above 0.5 with mean, Ga, roughness, entropy and normalized ACF.
