The present work investigates BUL formation on pcBN tools for dry, high speed machining of GG25 grey cast iron (up to vc = 750 m/min). This work suggests that the BUL distribution on the tool at high cutting speed (vc = 750 m/min) is key to tool protection. Protection in the area of maximum cutting temperature is critical in preventing thermally driven wear modes, such as crater wear, found at low cutting speeds (vc = 250 m/min).||Funding Details:||Enterprise Ireland||Type of material:||Journal Article||Publisher:||Elsevier||Journal:||CIRP Annals - Manufacturing Technology||Volume:||65||Issue:||1||Start page:||93||End page:||96||Copyright (published version):||2016 CIRP||Keywords:||Cubic boron nitride (CBN); Cutting tool; Grey cast iron||DOI:||10.1016/j.cirp.2016.04.045||Language:||en||Status of Item:||Peer reviewed|
