Mill Fracture Mechanics

Adaptation of Fracture Mechanics Methods for Quality

Tungsten carbide WC is well known as one of the hardest materials widely used in machining cutting and drilling especially for cutting tools production Knowing fracture toughness grants the opportunity to prevent catastrophic wear of a tool Moreover fracture toughness of WC based materials may vary because of different material compositions as well as a different way of production
