Ultrasonically assisted high speed nano-micro milling for nanotechnology quality
Abstract
This proposal describes a preliminary study aimed at developing a fundamental understanding of ultrasonically assisted high-speed nano-micromilling in a variety of hard or ductile material. Nano- micromilling is an enabling technology for the fabrication and commercialization of micro-and nanodevices. The main scientific objectives of the project are to :
- Establish the effect on the cutting process of process parameters such as tool characteristics, material microstructure, kinematics of superimposed motion, or cutting speed
- Quantify the effects of process parameters on the resulting part geometry, dimensional tolerances and surface quality
- Outline modeling approaches for the micro-nanomilling process
The practical benefits of the project include :
- Quality improvement to attain tolerances and surface roughness on the order of 10 nm or less
- Reduction in cutting forces
- Reduction in tool wear
Ability to machine hard materials : tempered steels, ceramics
