The material removal rate is chosen as optimization objective.
First, users query the database system for workpiece materials, manufacturing process information of the workpiece,cutting tools and machine tools of the process and other information according to their own processing requirements.
The cutting database should have nice extensibility and convience to add new data of materials, toos and proven cutting parameters.
The main function modules included cutting tools management, machine tools management, workpiece materials management, recommendation of processing parameters and system managemnt.

Fig 12 Hassaini medium-scale bridge on Fig 13 A moraine slope between KKH and ice construction at K676+450 tongue Engineering background.
Strictly speaking, the engineering property of soil has a certain non-linear character.
But when the soil is subjected to the normal load, the plastic range is so small that soil can be regarded as a linear elasticity material.
One is engineering prevention measure, the other is hazard management.
The engineering prevention measure should depend on the damage types and classes.

In the process of working devices working, by the gravity of materials, as well as by the shovel work process instantaneous impact load, cyclic loading by both the impact of the work, it is easy to break the weak links in the corresponding part of the working device, short the working device life which can not even be used[1,2].
Key technologies of rigid-flexible coupling system modeling The establishment of loader working device model.
When working device partial load, it suffered stress greater than the limit of material yield.

Such a kind of analysis can be used both in theoretical consideration of material engineering problems and in the chemical industry.
Introduction Random packings of spheres have many reflections in materials science.
Real materials, such as oxides or sulfides, include at least two elements with atoms of two different sizes.
In spite of the great importance of the problem for materials engineering, only general algorithms have being proposed; they give satisfactory approximations in some selected cases.

Silica aerogels, as the one of raw materials, can significantly increase the content of mesopores and reduce the thermal conductivity of the materials.
In this study, we prepared insulating materials, with mesopores contained and quartz fiber reinforced, by microsilica, silica aerogels and quartz fibers as raw materials.
Experiment Raw materials Microsilica (95.5%) was provided by Elkem Silica Materials (Kristiansand, Norway).
Conclusions Insulating materials, with the best properties in present study, could be prepared by microsilica, silica aerogels and quartz fiber as raw materials.

The core idea of LC is that in ensuring the quality and safety conditions strive to achieve zero waste, zero failures, zero defects, zero inventory, and strive to achieve the shortest period and a minimum consumption of resources, to achieve the goal of the wasting minimization, customer value (or engineering value) maximization.
From the overall perspective of LC techniques and methods, this article explores the key factors that affect the implementation of LC.
To this end, according to the actual situation in the construction process of the construction project, through project management expert interviews and field research in the construction site, summarizes the key factors in the implementation of LC, they are: weekly Percent Plan Complete(PPC ); grassroots manager (foreman) participate in weekly work plan; according to the completion of weekly work plan to adjust monthly plans; Public announcement tasks standards; schedule, quality and safety information publicly posted; each foreman (employees) signed undertaking to fulfill tasks; meet every morning to discuss yesterday's work and arrange work today; weekly meetings of grassroots managers to discuss the problems of last week working to arrange next week; construction links closely coordinated, and no waiting between them, also no extra processing; constraint management of the construction process in a variety of specifications and requirements; materials, manpower, equipment at the stipulated
In surveyed project, civil engineering projects accounted for 55%, industrial construction projects accounted for 12% , the municipal utility industry construction projects accounted for 17%, and 16% of other types of projects.
