Abstract
As a new precision processing technology, laser polishing is widely used in metal and non-metal. Laser polishing technology is especially suitable for parts with high hardness and small size. In this paper, a full factor experimental were carried out to investigate the effect of continues wave laser with a wavelength of 1064nm on the surface quality of additive manufacturing Ti6Al4V. The experimental result shows that a smooth surface can be obtained and the average roughness is reduced from 14.95μm to 1.756μm with the reduction rate is as high as 88.3% when laser power is 170W and scan speed is 60mm/s. And the height of the peaks and valleys on the sample surface has also been greatly reduced in condition of the optimized laser processing parameters.
