A Failure Analysis of an Experimental AIMgB14 Cutting Tools



J L. Evans, Laurent Deshayes, D G. Bhat, S A. Batzer


A recently developed ultra-hard boride-based material, AlMgB14, has been fabricated into a standard cutting tool geometry (TPG-222) and tested in the single-point turning of Ti-6Al-4V. The initial testing was conducted to compare this new cutting tool?s performance relative to a WC-Co cutting tool. During these tests a number of the inserts manufactured from the boride-based material suffered catastrophic failure for a wide range of cutting conditions. Consequently, a failure analysis was conducted of these inserts.
