In recent years, micromachining technologies have been widely developed to achieve 3D features in many materials that show more potential to being applied to engineering materials in the micro-fabrication domain [1-2].
The high accuracy and quality of products are achieved by ultra-precision machining technology, which are the trend of modern manufacture science and engineering and the base of modern science and high-tech[6-7].
The material of micro cutter is tungsten carbide.
It was easy for the removal of the material at this situation.

Recent interest in fiber reinforced polymer composites modified with CNTs, known as “Multiscale Composites” as they have been reinforced with microscale fibers and nanotubes at the nanoscale [6, 7], have attracted the researchers in the area of advanced, high performance materials.
Experimental Details Materials.
Halpin – Tsai Model (H-T Model) H-T model is a semi-empirical model and the longitudinal and transverse moduli are expressed in Eq. 2 Halpin -Tsai [11,12,&13] and Hill-Halpin [14,15] developed the equations based on the work of Hermans [16] for aligned fiber-reinforced composite materials.
