Introduction The machining characteristics of engineering materials depend primarily on their mechanical and chemical properties.
Such properties depend on the machining process and the engineering materials used in production.
The chemical constitution and the mechanical property of this ultra-high strength alloy steel are listed in Table 1.
The factors and levels are shown in Table 2.
Moreover, due to the pretty high plastic property, mechanical hardening effects appear which leads to the fracture of primary cutting edges.

Structural Serviceability factors are deflection due to bending, floor vibration, shrinkage [2].
Wood has a number of great properties – strength, flexibility, toughness etc.
The values of wood mechanical properties are diverse in various directions.
Mechanical strength properties of wood are influenced by a number of factors – wood moisture content, density, knots and other wood defects etc. [6].
Therefore, to determine factors affecting the bending strength performance of the glued T-type spruce loose tenon construction joints with and without reinforced plastic clamp fitting, a series of empiric laboratory tests have been conducted in this study to determine the effect on bending load carrying capability of the glued T-type spruce loose tenon construction joints with and without reinforced plastic clamp fitting.

Two main influence factors are discussed; they are performance of the inerferimetric microscope and the stage.
Introduction Spherical and aspherical surface provide superior performance and optimize the structures in mechanical design.
Thus the decreasing contrast of the fringe is the main factor limiting the measurement of spherical and aspherical surfaces.
According to the diffraction grating properties [4], the movement of diffraction grating along X direction is in direct proportion to phase shifting of the interference fringes, thus the displacement can be calculated by detecting the phase shifting.
Two main component parts are discussed, however, there are also some factors, such as the spherical dispersion influence on the algorithm and the grating measurement error, which should be carefully considered.

Magnetic properties of electrical steels such as magnetization behavior and electrical losses are mainly related to chemical composition, crystallographic orientation and microstructure.
By now, several models have been proposed to empirically correlate magnetic properties and affecting parameters.
Introduction It is well known that the magnetic properties of electrical steels such as magnetization behavior, electrical losses, permeability and coercivity are related to the microstructure, chemical composition, texture and the mechanical conditions (e. g. stresses) of the laminations in the core [1].
Between all the microstructural parameters, grain boundaries, inclusions and surface defects have a strong influence on magnetic properties by pinning the motion of domain walls and increasing the coercive force of the material.
However, more research work needs to be done on more samples to find a physically based formula, which describes the combined effect of the microstructural and magnetic field variables on the magnetic properties.

This has compromised some of the mechanical properties like tensile strength and microhardness.

Nanocomposite coating films have been increasingly used in industrial applications because of their unique mechanical and physical properties.
Introduction Nanocomposite coating films have been increasingly used in industrial applications such as high-speed machining, tooling, optical and magnetic storage devices because of their unique mechanical and physical properties [1].
The elastic and thermal material properties used for the film are shown in Table 1.
Table 1 Material properties of Ti0.39-Si0.04-N0.57 film.
An elastic material model was used to describe the behaviour of the film using the material properties shown in Table 1.

The results of this process are chips and the core that can be used to produce other element, particularly if the material is expensive or if it can be used to examine properties and quality of the material.
Physical model of the friction process describes, besides effects that occur in the milling area, also other factors that influence the course of the drilling process.
Physical model of the drilling process During operation of trepan cutters (Fig. 4), beside physical effects that occur in the milling area, there are also other factors that influence drilling process.
These factors influence also the state of milled surface: chemical composition, roughness, microhardness.
Then, on the basis of the research, the physical model was build that describe factors influencing operation of trepan cutters.

In micro-EDM, two poles maintain non-contact and mechanical stress is not introduced.
The following discusses the factors of the micro-EDM process, which guarantees machining precision.
The discharge gap and its deviation are related to processing factors; thus, experimental research should be performed.
It is because reduction in insulating properties in the low resistivity makes the conductive enhance, and the short-circuit is very easy to happen, then the process is unstable and it is like to cause changes of micro-hole diameter.

Ceramic material has preferable properties in mechanical and thermodynamical aspects, these materials are generally very hard and their heat conductivity is low.
These advantageous properties of ceramics make the material difficult to machine using the traditional mechanical (cutting) processes.
The latest review article by Pachaury et al. [2] gives a collection of the affecting parameters.

Other in-plane mechanical properties test.
Thus, comparison of the in-plane static mechanical properties of two kinds of composites at room temperature was carried and the related standards were also listed in table1.The stiffness of 0° tension, 0° compression and flexure property of T800/5228E were decreased, but other mechanical properties like 90° tension, 90° compression and in-plane shear stiffeness and main strength characterization were not affected or even gained some improvement.
The mechanical properties of composite laminate depends on its constructure.
