Abstract
This paper describes the research results of surface quality research after the sintered carbides turning by the tools with edges made of polycrystalline diamonds (PCD). The research trials were conducted for tools with different nose radii and the influence of three independent parameters (vc, f, repsilon) affecting the surface roughness were analyzed. The impact of the binder material content Co (cobalt) on the surface quality during the turning process (according to the values of surface roughness parameter Ra) is described further on. The values of vc, f, repsilon at which the smallest surface roughness (for the particular work piece materials) could be achieved were defined. Based on the ANOVA variance analysis it was possible to find different effects of the research factors on the surface roughness (for the two types of sintered carbides shafts). For the shaft with 25% Co content, the significant influence is for two parameters: the cutting speed vc and the nose radius repsilon. For the shaft with 15% Co percentage content, the significant influence is only for the nose radius repsilon.
