Research on the Precision Machining on SiC Qiang Xiao Xueli He 1.School of Mechanical and Electronic Engineering, Xi’an Technological University, Xi’an,710032, China； 2.School of computer science, Shannxi Normal University， Shannxi ，Xi’an， 710062，China xiaoqiang@xatu.edu.cn Keywords: surface quality; mechanism; precision machining Abstract: SiC material removal mechanism and ELID grinding mechanism is analyzed, the character and condition of brittle to ductile transition of SiC single crystal, the critical depth of cut, and surface formation mechanism of ductile mode grinding of SiC single crystal are studied, the experiment results show that ELID grinding can realize ductile grinding ,this will lower the surface damage and improve the machining efficiency.
Introduction Fig.1 SiC Single crystal With the rapid development of technology, SiC single crystal become a important third generation of semiconductor materials, shown in Figure 1,because of its superior attributes, such as wide band-gap, high-breakdown electric field strength, high-saturated drift velocity, high thermal conductivity, low coefficient of thermal expansion, strength at elevated temperatures.
Material removal mechanism Material removal methods are generally two kinds of brittle fracture and plastic removal, shown in Figure 2, Figure 3，Figure 4.
Therefore, the dissolution of bond material increases and the exposure of diamond grains restart.

Fig.5 Sketch of microhardness testing points Fig. 6 show that the hardness of each specimen increases along height direction which is basically consistent with the gradient materials design[14].But,it can be seen from each contour line that hardness distribution fluctuates wildly without ultrasonic vibration.
(1) Ultrasonic vibration will help to suppress the formation of pore and reduce its size； (2) By analysing the microstructure of middle cladding layers, it can be found that the grain size is refined for ultrasonic vibration breaking the longer dendrite;Furthermore,in the FGMs specimens, reinforced phase TiC particle size is smaller and get more uniformity distribution; (3) The microhardness tests indicate that gradient materials specimens have good hardness consistency and high mechanical property, which show the ultrasonic vibration can refine the cladding layers and homogenize the microstructure，and then improve its mechanical property.

In order to obtain well bore stresses in hostile conditions, a new model is established with cement sheath and formation are treated as different materials.
In this paper, cement sheath and formation are treated as different materials, a new model is established to calculate stresses in casing, cement sheath and formation, and hostile conditions as HP/HT and non-uniform earth stress are included.
Data are obtained under assumption that three materials are linear elastic and isotropic.
