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)...
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.
The coefficient of chip contraction or chip reduction coefficient is a quantitative measurement of plastic deformation that occurred during the cutting process. or Chip reduction ratio.
