The tool is positioned at a fixed distance below the core while cutting. This chip formation corresponds to the thickness of the chip before t1 as the chip is formed along the shear plane. Its thickness increases to t2(after the cut chip thickness). The chip thickness ratio is defined as the thickness of the metal … See more As the tool is forced into the materials, the chip is formed by shear deformation along a plane called the shear plane, which is oriented at an angle with the surface of work, known as the … See more Coefficient of chip contraction Shortening of the chip length is known as longitudinal chip contraction. The inverse of the chip thickness ratio is known as the chip reduction coefficient.
