- •
The experimental results obtained on the machining of ferritic and pearlitic ductile cast iron point to the TiAlN coated tool as the most suitable in the machining of ductile cast iron.
- •
The proposed tool wear mechanism is based on like intermittent cutting caused by the pass from hard matrix to the soft graphite occasioning wear by adhesion.
- •
The change in wear rate observed in the logarithmic plots was related with the wear out of coating layer. The partials loss of coating layer on cutting edge was confirmed by the SEM and EDS mapping images.
