    - The metal is removed in the form of chips in metal cutting operations with the help of cutting tools.

    - In this process, when the compression limit of the metal in front of the cutting tool has been exceeded then it is separated from workpiece and flows plastically in the form of chips.

    - The localized region in which the plastic flow of metal takes place is called as shear plane.

    - The below diagram shows the formation of chip in metal cutting.
