Failure of polycrystalline cubic boron nitride (PCBN) cutting tools, resulting from microcrack development, is one of the major causes of tool replacement in the machining of advanced materials. In this research, the J-integral method is applied to study the relationship between crack growth in a cutting tool and tool life in a hybrid machining process. Results show that with the decrease of the cutting temperature and its gradient in the cutting tool, the J value decreases and the tendency for micro crack propagation in the tool declines. Therefore, tool wear and early fracture rates are remarkably reduced.
