As the cutting speed increases, cutting temperature becomes one of the most important factors restricting high speed machining which is associated with high materical removal rate and high induced temperature.
Heating and cooling affect tool insert alternately, and the temperature of tool insert increases first and then decreases in a milling operation period.
In order to simplify the tool insert temperature problem, we consider the thermal properties of the tool insert material as independent of temperature and heat radiation is regardless.

Factors affecting the promotion of wood saving and substitution technologies in the packaging of electromechanical products With the development of green economy, the promulgation of energy saving and emission reduction policy, and the enhancement of sense of social responsibility of enterprises, China has made proactive exploration in the field of wood saving and substitution in the packaging of electromechanical products.
Focus on the research on mechanical properties of different wood substitution materials, structure of packaging products, and mechanical properties of structural members, connectors, and structural connectors so as to provide scientific and theoretical basis for the design and structural optimization of packaging products, and based on the research, propose normative and strict dimension definition for different weight bearing structural materials, and formulate related standards, including: (1)Research on mechanical properties of packaging materials (physical and mechanical property indexes of biomass materials, constructive relationships of materials, and material grades) (2)Safety grade of large packaging boxes (importance classification and reliability design of packaging boxes) (3)Normalization and standardization of packaging box load (static load, action of driving forces in various carrying conditions, temperature stress, working load, and so on) (4)Structural analysis methods
Furthermore, due to uneven rotary cutting thickness of veneers, uncontrollable factors impose greater influence upon the production process specifications.
Laminated veneer lumbers for packaging electromechanical products are structural laminated veneer lumbers and shall have perfect water resistance, weatherability and mechanical properties.

According to these factors, the high strength steel should be widely used in automotive parts.
In these processes, the properties of roll forming basically meet the needs of the high strength steel, and this forming process is gradually accepted by other industries.
Low strength steel has this property.

The transformation from austenite into martensite causes an increase in volume, then the volume fraction of martensite directly impacts the residual stresses and mechanical properties Conclusions High-strength steel is the most effective way for energy saving, emission reduction, improvement of vehicle safety, while the roll forming process fully makes use of the performance of high strength steel.

Due to the polymeric nature of adhesives, the variation of the mechanical properties of the adhesives with temperature is one of the most important factors to consider when designing a bonded joint.
However, the properties of adhesives over the range of service temperatures need to be studied for each type of application.
Below Tg it is difficult to say at which temperature the lap shear strength is the highest as there are two factors to consider: the ductility and the strength.

The most common titanium is the type two phase Ti-6Al-4V alloy among several alloying types of titanium, because of its good comprehensive properties[2].
The machine ability of titanium and its alloys is generally considered to be poor owing to several inherent properties of materials.
This machining technique is applicable to a wide variety of conductive materials irrespective of their mechanical properties, such as their hardness, strength, or toughness, etc.
The material properties of Ti-6Al-4V alloy are showed in Table 1.
However, the shape and size of crater is related to many factors such as discharge parameters, material itself, working fluid and discharge gap etc.

The comprehensive evaluation model for aircraft Three-Proof performance under the influence of multi-factors is established by using the technology of multi-index comprehensive evaluation synthesis.
On the other hand, it may produce corrosion and destruction in combination with other environmental factors, such as the salt air and some organisms.
The growth of mildew directly (degrade) or indirectly affects (by deposited pollutant) the equipment, changes its physical properties, and then affects the function and use of the equipment, for instance, reducing the electric performance of insulation materials, causing malfunction of electronic or electrical equipments, causing corrosion and jamming of the fuel system, destroying the seal, causing metal corrosion, and etching the glass.
By integrative consideration of the above factors, the aircraft Three-Proof evaluating index system supported by seven major evaluating points is established, as is shown in Table 1.
These may be caused by some experts giving weights that are quite different from the real value owing to their unfamiliar with the properties of some indices, owing to the strong subjectivity of the survey data.

The related surface properties are also reviewed in order to strengthen the review of adhesive properties and tribology.
