Abstract

Many of the currently used tool materials will dissolve, diffuse, and/or react with titanium due to high temperatures at the tool/work-piece interface. Potential next generation tool materials that would improve the machining of titanium and eliminate the contamination of the work-piece are being developed. One such material, AlMgBB14, is the subject of the research presented in this paper. Specimens of the newly developed tool, AlMgBB14 were fabricated into a standard tool geometry. This tool material was compared with a standard WC-Co tool material to machine a Ti-6Al-4V work material. Thermal and force measurements were conducted using both types of tools during orthogonal cutting. Results are also compared with finite element simulations. The paper outlines that higher temperatures are obtained by AlMgB14. It is also shown that this material is more appropriate to be used with high cutting speeds. Nevertheless, a weakness of this newly developed AlMgB14 B is its toughness that needs to be improved for better performance in an industrial environment.
