Abstract: An experimental study on cutting material 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
mechanism for the chip formation in the cutting of amorphous alloy is
discussed. It is found that the deformation along the direction of chip
flow occurres at first before localized shear really happened, and a
simplifying geometrical model is proposed to illustrate the deformation.
