During the machining process, the tool is exposed to considerable thermal and mechanical stresses. Thermal stresses at the chip/tool interface can reach thousands of degrees. In addition, the plastic deformation of the material generates reactive stresses that cause the tool to bend and vibrate. Since machined materials are rarely homogeneous in nature, stresses vary rapidly, increasing the risk of cracking. The combination of high temperatures, particularly thermal shock at the start of machining, and vibration can lead to crack formation in the tool.
