Due to the demand of the manufacturing industry for high production-rate machining, ceramic tool material plays an important role. In this work, alumina (Al2O3) matrix composite reinforced with 0.3 vol.% multiwalled carbon nanotubes (MWCNTs) was prepared by hot-press sintering at a temperature of 1550°C under uniaxial load of 2.5 MPa. This developed nanocomposite having increased hardness, fracture toughness and flexural strength compared to monolithic Al2O3 was then used as a cutting tool insert with a nose radius of 1 mm for machining AISI 1060 steel rod under different machining conditions. Cutting force was measured and chip forms were observed at different levels of machining parameters to evaluate the machining performance of the tool insert. Results obtained from turning experiments show promising applicability of the developed 0.3 vol.% MWCNT/Al2O3 cutting tool insert.

This developed nanocomposite having increased hardness, fracture toughness and flexural strength compared to monolithic Al2O3 was then used as a cutting tool insert with a nose radius of 1 mm for machining AISI 1060 steel rod under different machining conditions. Cutting force was measured and chip forms were observed at different levels of machining parameters to evaluate the machining performance of the tool insert. Results obtained from turning experiments show promising applicability of the developed 0.3 vol.% MWCNT/Al2O3 cutting tool insert.
