• Nanotechnology

Background:

• Taper-cutting experiments are crucial for understanding nano-cutting mechanisms in hard and brittle materials.
• Current methods for determining brittle-ductile transition depth (BDTD) are inefficient, costly, and lack in situ measurement capabilities.
• Existing BDTD measurement techniques using 3D microscopy and 2D image analysis are subjective and inaccurate.

Purpose of the Study:

• To design and establish an integrated system for processing, measurement, and evaluation of taper-cutting experiments.
• To overcome the limitations of traditional ultra-precision machining tools and subjective measurement methods.
• To enable efficient and accurate in situ determination of BDTD in hard and brittle materials.

Main Methods:

• Development of an integrated system platform for taper-cutting experiments.
• Utilization of a spectral confocal sensor for workpiece assembly and adjustment.
• Integration of a white light interference sensor for in situ 3D topography measurement of cutting surfaces.
• Proposal of a novel BDTD calculation method using 3D data supplemented by 2D images.

Main Results:

• The integrated platform demonstrated stable and reliable taper-cutting performance, consistent with ultra-precision machining tools.
• The proposed measurement method, combining 3D data and 2D images, proved accurate and feasible for BDTD determination.
• Successful fabrication of microstructure arrays on the platform showcased its high-precision application potential.

Conclusions:

• The integrated system provides a stable, reliable, and efficient solution for taper-cutting experiments and BDTD measurement.
• The novel BDTD calculation method enhances accuracy and reduces subjectivity in material analysis.
• The platform is suitable for high-precision applications, including the fabrication of microstructures.
