The machining of difficult-to-cut materials such as titanium plays a key role in several industries such as aerospace or medical.
During the machining of hard-to-machine materials such as titanium, high temperatures occur at the interface between tool and workpiece due to the low thermal conductivity of titanium [1].

Introduction In recent years, low-dimensional quantum structure materials become the one of the investigation hotspot due to their some special electrical, magnetic, and optical properties which cannot be observed in-bulk-materials.
Atomic force microscope (AFM) is powerful tool to investigate the electronic properties of nano-materials, since the small pinpoint guarantees the high resolution in nano-scale and can be moved to the subtle area where one concerns.

Among the non-traditional machining methods currently proposed for the hard-brittle materials, rotary ultrasonic machining (RUM) is regarded as a relatively cost-effective process that combines the material removal mechanisms of ultrasonic machining (USM) and conventional grinding (CG) [1].
Since the birth of RUM in 1960s, it was primarily applied to drill core hole on brittle materials [3].

Moreover, “unlike other areas of science education, the understanding and research on how to teach the core ideas of nanoscience and nanotechnology is still emerging” [1].TheK-12 program is one ofthe Taiwan National Science and Technology Program for Nanoscience and Nanotechnologyand aims to cultivate talent of nanotechnology.
It can deal with the size of structure from 1 to 100 nanometer at least one dimension, and involves developing materials or devices within that size[3].
“Nanotechnology allows us to make materials that are thousands of times smaller than the smallest cell in the body” [4].
It shows that all the four domains are concerned about the inherent feeling of learners.The researchers suggest that it can be rely on supervising different departments to develop different materials of departments.
