【 摘 要 】

Magnesium alloy is more suitable for biomedical metal material compared with traditional metal materials, as it has the similar mechanical properties with human bone and biodegradable property. Surface roughness influences the friction and ware properties, corrosion resistance and fatigue resistance, then the service life of parts. It is important to search the influence of magnesium alloy milling process on surface roughness as a certain connection exists between roughness and corrosion resistance. In this paper, the influence of cutting speed, feed, axial and radial depth of cut on surface roughness had been analyzed after the orthogonal milling experiments. Finished surface roughness model had been established and verified.
