This project involves theoretical and experimental research on the              causes of fracture in cutting tools.  Prior research has shown that for         carbide tools the strain of fracture is the same under static and               dynamic conditions for uniaxial tension and that fracture occurs                without plastic flow.  This research also showed that when the forces           are mainly compressive, plastic flow occurs before fracture.  This              research will be extended to ceramics and cermets; however, the main            focus will be on studying the compressive forces that occur during              rapid loading and unloading of the tool, at the beginning and the end           of a cut.  The research will involve both cutting experiments and               finite element analysis of tool tip stresses.
