Fundamentals of Cutting
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 Metal Casting Process Explained General Kinematics
The History of Metal Casting . The oldest known metal casting is that of a copper frog believed to have been produced in 3200 BCE in Mesopotamia when copper was a popularly used material. Later around 2000 BCE iron was discovered. But it was not until around 700 BCE that the first production of cast iron was developed in China.
