The axisymmetric radial vibration equation of the thin disk with variable thickness in Cylindrical coordinate can be expressed as follows: (1) Where is radical vibration displacement, is the function about the thickness of the edge section, is material density, is Poisson ration, is material elasticity modulus.
Defining the material parameters of duralumin as follows: density(r) =2 700 kg/m3, Poisson ratio(n) =0.34, elasticity modulus (E)=71.5 GPa.
Second, the material parameters selected in the analysis may be different from the true value.

Guangdong Academy of Social Sciences suggested that Guangdong now faced with a series of new challenges: First, resource-dependent development of epitaxial growth model, has been faced with resource and environmental challenges of tight constraints, likely to lead to unsustainable development crisis.
This mode of development, on the one hand achieved three decades of brilliant, on the other hand, Guangdong is entered into the dilemma of not sustainable: within the limits of ensuring sustainable development, land resources had become exhausted, extension development is approaching the limit, and the growth model of extension expansion can’t be sustainable; With the increase of economic development level, and the rapid increase in labor costs, labor-intensive industries will be difficult; the extensive processing and manufacturing system, which rely on a lot of consumption of material resources as the prerequisite, is facing the severe impact of a global shortage of resources and price increases; the fierce international competition is leading to the beginning of the policy of government intervention in the Western countries and protectionism in international trade, and export-oriented labor or resource-intensive processing and manufacturing industry caused great international pressure
For example, in personal computer, there is about 7% of copper, 14% aluminum, 20% iron , 2% zinc, plastic 23% and other environmentally friendly and high-value material about 66%; it also contains 6% lead, 0.002% mercury and 0.009% of cadmium and other substances harmful to the environment up to around 6%, glass and other material about 28%.

Cobalt silicides attract much attention because of their possible application as interconnect material.
These studies suggest that linear interface shift may occur due to large difference in the diffusion coefficients of the materials in contact (diffusion asymmetry), even if there is no any extra potential barrier present, accounting for an interface reaction control.
Multilayered samples were used to increase the amount of material to be detected.

Keyseat is an important geometry for this function on the shaft[1].Plain key is a kind of most commonly used keys, and with plain key both the journal of the shaft and the hob are required to make the keyseat.
Precision journal is even machined to the tolerance class of IT5, and tolerance of counterpart keyseat is rather high that can hardly be reached with the common methods[2].
Material of the work is 45,that of the cutting tool is HSS with ,teeth = 14, diameter of the three-face cutter is φ28mm,width B=10mm, ,.
