    - Tool failure can be defined as the point at which the cutting tool reaches, beyond which it will not function satisfactorily until it is reground.

    - The phenomena like tool wear, tool breakage, tool chipping and tool deformation reduce the usefulness of the cutting edge.

    - Tool wear is responsible for most of the tool failures. It involves mechanical, physical as well as chemical processes and sometimes in combination.

    - Tool wear is very complex process.

    - Tool wear can be defined as the loss of weight or mass that accompanies the contact of sliding surfaces.
