Experimental analysis of tool wear when drilling carbon fibre composite (CFC) without cutting fluid, with cutting fluid and with a pre-cryogenically cooled tool

Machining of Carbon Fibre Composites (CFCs) particularly drilling, is frequently employed in industry especially when dealing with joining, assembly and structural repair of the parts. However, the nature and heterogeneous structure of CFCs often results in rapid wear of the cutting tool. This resea...
