摘要：

In parallel machining of aluminium and cast iron hybrid components, like in precision boring of crankshaft bearing bores, a tribo-chemical reaction occurs on the rake face of a cutting insert and comes along with significant built-up edge formation. Cooling strategies (external, internal) and the cutting fluid quality show significant influence. The determination of the temperature dependency of the intermetallic compound formation velocity (Fe-Si-C) gives a better understanding of this particular tribo-chemical process. An internal cooling of the cutting insert allows a reduction of the built-up edge effect by reducing the temperature on the rake face. (C) 2016 CIRP.
