Abstract: An experimental study on cutting amorphous alloy at nanometer
scale is conducted by applying the principle and technology of
scanning probe microscope(SPM).It is revealed from the
experiments that cutting inside SPM is an excellent and direct
way to research the material removal process at small size.
Based on the experimental results, the chip formation mechanism
for the cutting of amorphous alloy is discussed. It is found
that the deformation along the direction of chip flow occurs
ahead of the appearance of localized shear, and a simplified
geometrical model is proposed to illustrate the deformation.
Key words: Scanning probe microscope(SPM) Nanotechnology Cutting mechanism
