According to the machining process of the factors causing error to occur any regularity, processing error into system error and the random error, According to the nature of the changes with time, and can be divided into static error and dynamic error.
Processing System Dynamic Error Analysis Many factors influence the machining accuracy of machine tools, in addition to the complex and static precision, also exists dynamic error.
In the machining process aspheric, these factors which influence the error in response to the final piece shape error.
Turning process includes various physical phenol, a large number of random factors, including due to a hot cutting of high temperature for machining accuracy has very big effect.
Many factors influence the temperature of cutting, reduce the heat cutting methods is to reduce the heat cutting and heat transfer speed.

There is therefore a need for models that predict the electroelastic properties and describe the deformation process of such piezoelectric materials.
Microscopic damages unlike submicroscopic damages, which under unloading, as a rule, vanish (are healed), are of irreversible character (i.e. they remain in the form of microcracks) and at a macrolevel are manifested as changes in mechanical properties of a material, in particular, in its deformability.
At the second phase, the method for determining effective electroelastic properties of the damaged medium and the model of accumulation of microdamages are employed.
To approximate distributions of the microstrength properties of structural elements the power law is used
Dependence of the stress from mechanical strain Because of the direct and inverse piezoelectric effect, we can see that the presence of an electric field affects the stress-strain dependence.

Many factors influenced the release and degradation of the PLGA release systems.
These factors included polymer composition, molecular weight, the interaction of polymer and drugs, properties of drugs, plasticizer or additives [1,4,5].

The mechanical behavior of ceramics under high pressures and temperatures is a subject of considerable interest.
Since high pressures can be generated under static or dynamic conditions, it is necessary to measure mechanical properties of the materials under both.
Material The relevant properties of titanium diboride, densities, bulk modulus and pressure derivative of the bulk modulus, and Hugoniot Elastic Limit (HEL), used in various investigations are displayed in Table 1.
A possible reason for this discrepancy is that the large magnitude of the Hugoniot Elastic Limit (HEL) of titanium diboride, i.e., 12-17 GPa, affected the Table 1 Properties of titanium diboride.
The results of such experiments would improve our current understanding of the shear strength of a solid under high pressures and determine the effects of factors mentioned above which may explain the differences in the values of shear strength obtained form shock compression and static compression experiments..

These factors must be compensated to produce adherent diamond coating on carbide substrates.
The first two factors are directly related to pretreatment of the carbide substrate prior to diamond deposition.
Immersion in Murakami’s reagent was intended to etch the WC grains without affecting the cobalt content [7].
Nonetheless, peroxide concentration’s net effect might still affect elsewhere, e.g. in reducing reaction time.

The results indicated that quench sensitivity and therefore the mechanical properties inhomogeneity in large plates or forgings can be predicted more accurately by the simultaneous combination of hardness and electrical conductivity measurements based on Jominy end quench.
Meanwhile, the depth of greater than 150 mm is achievable in the novel alloy, and hence it can be recommended to fabricate large section plates or forgings without compromising properties in the center of the part after a slow cool.
Introduction Al-Zn-Mg-Cu series Al alloys are widely used for structural applications in aerospace because of their specific mechanical properties, which are precipitation or age-hardenable [1-5].
Quench sensitivity of age hardenable aluminum alloys are dependent on various factors including alloy composition, processing, quenching type, quenchant media selection etc.

The effect of the treatment of metal parts depends on various factors: the initial microstructure of delivered material; surface topography; residual stresses prior to and following the shot peening process.
SP treatment with a suitable intensity value normally has a positive effect on surface properties, which can be attributed to the occurrence of compressive residual stresses that prevent the initiation of micro-cracks and their propagation, regardless of changes in surface roughness and possible damage.
The chemical composition of the alloy and its mechanical properties are given in Table 1 and Table 2.

Introduction The plain carbon steel such as S45C is widely used for the mechanical parts such as the automotive parts.
It is well known that the surface roughness is one of the most important criteria for the mechanical parts in CNC turning.
Several factors affect the surface roughness such as the machining parameters, the cutting tool properties, the workpiece properties, and the cutting phenomena [1].
The feed force (Fy) is most sensitive to the surface roughness and the main force (Fz) is affected by the cutting conditions [8].
The cutting conditions may affect the tool wear and the cutting temperature.
