Analys av eggnära geometri: Empirisk studie av geometrivariationer hos CNMG 120408
Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
In the autumn of 2010 a geometry analysis was done at AB Sandvik Coromant in Sandviken. This analysis was an empirical study of micro- and macro-geometries of Articles CNMG 12 04 08 PM and CNMG 12 04 08 PR. In laboratory tests cutting data was optimized to provoke occurrence of the following deformation types; ductile fractures, two types of plastic deformation and flank wear. Furthermore, cutting forces were tested along with chip breaking. The results of this study show that the micro-geometry changes introduced do not affect chip breaking while cutting forces and deformations are affected. Briefly, the result may be described as a linear relationship in which a geometry may have enhanced properties of resistance to ductile fractures and edge depression, in which cutting forces and characteristics of resistance to edge impression and flank wear receives adverse effect, or vice versa. This is true except for the dipping of the article CNMG 12 04 08 PR, where the result of the different geometries always was of the same or higher level compared to the reference.
