Goal

An aerospace parts manufacturer was running very short tool life on a roughing operation in Inconel 718 and needed an insert that could deliver more parts per cutting edge while bringing down total machining cost.

Strategy

The previous insert was wearing out after a single part per edge in the demanding heat-resistant alloy. Kyocera engineers recommended the CNMG insert with the MS chipbreaker geometry paired with the CA6515 grade, a CVD-coated carbide engineered for stable, reliable turning in tough materials like Inconel.

Result

The new insert delivered a 300% increase in tool life, a 113% improvement in material removal rate, and an 81% reduction in tool running cost. The customer saved more than $46,000 annually.
