Communication avec acte; ;LESCALIER, Christophe; ALAIN, D'acunto (ENIM Editions, 2010)
Metallurgical solutions for an improvement in machinability currently use nonmetallic inclusions in order to create solid lubricants at the interfaces between tool and workmaterial. It is possible to identify and quantify ...
