LASER HARDENED CRANKSHAFT

A method of crankshaft laser hardening includes grinding one or more surfaces of a green crankshaft to produce a green ground crankshaft and to define journal geometry thereon prior to hardening of the surfaces to avoid loss of compressive stresses associated with grinding a hardened crankshaft. The...

Zusammenfassung:	A method of crankshaft laser hardening includes grinding one or more surfaces of a green crankshaft to produce a green ground crankshaft and to define journal geometry thereon prior to hardening of the surfaces to avoid loss of compressive stresses associated with grinding a hardened crankshaft. The method also includes laser hardening the surfaces of the green ground crankshaft to induce compressive stresses.
