- Abstract
Based on the surface quality of the laser melt district from assembly parts and clearance fit exercise, the single factor experiments and orthogonal experiments were adopted to study the effects of laser power, laser scanning speed and laser hatch space on the surface roughness of the molded parts, and to study the effect of laser energy density on spherical pair fit motion. The results show that when the laser power is 200 W, the scanning speed is 550 mm/s, and the hatch space is 0.12 mm, the surface roughness of the molded parts reaches the minimum value of 12 µm; when the cavity ratio of the spherical pair is 0.2 and the physical density is 60-90 J/mm³, the spherical pair clearance has no obvious adhesion and the cooperative motion is better.
