Some materials, especially those with worse machinability, cannot be cut at all with these technologies.
These limiting factors have led to the development of so-called unconventional methods suitable for machining and cutting materials.

Therefore as the most important material for the concrete additive, price and supply of industrial naphthalene have a direct influence to the production cost and profit for the synthetic additive and composite manufacturer[1].
Given this fact, one of the biggest problems bothering the additive production in our country is the low resource efficiency, increasing shortage of materials, climbing price which would definitely contribute to a higher product cost.
Therefore, polynaphthalene sulphonate is not used directly but only after adding other ingredients according to construction requirements and local materials as well as weather conditions.
Thanks to This article is an accomplishment of natural science foundation project of Guangxi Economics and Management Cadres College (Project code: 08CE08051001), hereby appreciate for great supports and helps from project team members for the composing and research on the project.

Suppose the collision is only occur in the single side of tooth face ,then the firce function could be describe as follow:
impact=Max0,Kq0-1e-cqstepq,q0-d,1,q0,0 q>q00 q≤q0 (10)
here q is the displacement variable ,which means the distance between two collision bodies ;q is the variable relative speed ;q0 is the trigger for displacement variable which means boundary distance that the collision force works or not ;K is the stiffness of coefficient ;e is the stiffness force exponent ;C is the damping coefficient ; d is the damping Ramp-up coefficient .These parameters such as K,e,C,d mentioned upon are lie on material of two collision bodies .If they are steel ,then K=e ,e>1 ,C=e/100 ,d=0.1 .suppose q0 is 0.01 .In order to analyze the material of gear is set as steel ,the parameter K will be get by computing and μ will be get by table looking-up .so far every parameter is ascertained
