Vibration-Assisted Machining
18.1 INTRODUCTION
There is a high demand for precision-miniaturized components made from hard and brittle materials such as glasses, lens, and advanced ceramics, high strength alloys. Such requirement cannot be achieved by conventional and advanced machining methods. For better surface finish, high accuracy and high precision at low cost, vibration is introduced to any of the workpiece, tool, and working medium during the vibration-assisted machining (VAM).
According to the frequency of vibrations, VAM systems can be a resonant one that operates at frequencies greater than 20 kHz and amplitudes less than 6 μm. On the other hand, the nonresonant system operates at frequencies up to 40 kHz and amplitudes ten ...
