Zusammenfassung: | In this study, an equivalent tool geometry was presented, while taking into account the cutting-tool nose and edge radii. The main idea consists in considering that the equivalent geometry induces the same cutting force components as the real tool. In this context, equivalent cutting angle, equivalent direction angle, equivalent uncut chip thickness, and equivalent depth of cut are defined for the new tool geometry. A dual contact at the tool-chip interface, sticking and sliding zones, is considered in the developed thermomechanical model. The influences of the nose and edge radii on the cutting performances are studied. A well agreement was found between analytical and experimental results for different cutting conditions. It is underlined that feed and radial forces are the most sensitive components to nose and edge radii. The proposed equivalent tool has great potential for other applications such as tool wear studying while considering coatings and chip breaker. |
