This means following problems will occur: time, labor, and material have to be spent continuously after a defect happens in the grinding process; the measured results are not the current surface quality information, which are needed in the modern manufacturing process.
The material of the workpiece is bearing steel.

To study the propagation behavior of Lamb wave in the plate and graphically show the effect of the initial stress on the dispersion relations, the following material system is considered: we take a steel plate, ,,.
For the given material system and initial stress, there exist only two variables, i.e., phase velocity c and wave number k in Eq.(21), the dispersion relation for and are respectively shown in Fig.2a and Fig.2b.

Study on the Reverse Designing for Water Cavity Model of Engine’s Cylinder Head Min Chen a, Xiao Xu Liu b, Jian Ping Tian c 1School of Mechanical Engineering, Sichuan University of Science & Engineering, Zigong 643000, China amin_chen99@163.com, bxiaoxu_liu@163.com, ctjp893@126.com Keywords: Cylinder head, Slicing method, Reverse design, CAD Abstract.
Slicing method is one kind of new reverse design technique developed in recent years, the basic method is that some material is used to fill the part to be measured, which has larger grayscale contrast with the part, then the part is machined with small size plane cutting, the image equipment is used to capture the cutting section image step by step, the data processing software is used to process the image captured, and to restructure the 3D model [2].
Because of the cylinder head is made by cast iron, the contrast between the machined surface and cast iron surface is strong, so the filling material is not used.
