Fundamentals of Cutting - IIT Kanpur

Thus the metal gets compressed very severely, causing shear stress.. This stress is maximum along the plane is called shear plane.. If the material of the workpiece is ductile, the material flows plastically along the shear plane, forming chip, which flows upwards along the face of the tool.. The tool will cut or shear off the metal, provided

5 Mechanics of Metal Cutting A cutting tool exerts compressive force on the workpiece which stresses the work material beyond the yield point and therefore metal deform plastically and shears off.. Plastic flow takes place in a localized region called the shear plane.. Sheared material begins to flow along the cutting tool face in the form of chips.. Flowing chips cause tool wear..
