【 摘 要 】

Due to their good biocompatibility, mechanical properties and corrosion resistance, the Co-Cr alloys are one of the metallic materials used for manufacturing medical implants. When talking about manufacturing, it is well known that a significant constraint for this type of products is their surface quality. For this reason, various researches focus on the way the required surface quality of a part can be achieved with the minimum cost and resources. The aim of the research presented in this paper is to analyse the cutting regime parameters influence upon part surface quality when dry turning a CoCrMo alloy by using TiAlN PVD coated cutting inserts. The research results consist of the interdependence between the surface Ra and Rz roughness parameters of the machined CoCrMo samples and the cutting data variation and of a prediction mathematical model of the Ra roughness parameter in terms of cutting regime parameters.
