Introduction Milling is a very commonly used manufacturing process in industry due to its versatility to generate complex shapes in variety of materials at high quality.
However, due to the elastic recovery of material in the elastic deformation zone and the partial recovery of material in the plastic deformation zone, the shape and size of the part will change in the opposite direction of deformation, which is known as springback.

Metallic materials – Tensile testing.

Through numerous tests on rock, the existence of the intermediate principal stress effect has now been well recognized as characteristics of the materials [4] [5].The unified strength theory proposed by YU takes into consideration the effect of all the stresses in the characteristics line field[6], which can reflect the effects of the intermediate principle.
The theory is especially versatile in reflecting effect to different extents for different materials.
