But it is difficult to guarantee the quality of the hole, there is a problem recast layers which seriously affected the physical and chemical properties of the hole.And the equipment and processing costs are high.
However, these methods are improving the slant hole drilling only external factors, which did not play a role in improving the processing mechanism or from nature.

Finite element analysis use the workbench in ANASYS software, external force is applied to the finite element model of the entire sub-frame affected by the reality of the situation, and then judge whether turn shaft fracture is fatigue damage or too much force more than the stress limit caused the break.
Conclusions (1) Known by the Fe-C phase diagram: The influence of material processing technology for rotating shaft is very big, if an item in the process of machining not reached the standard of turning shaft, will great damage to the mechanical properties of shaft, the shaft has a deep rift, is likely to be due to errors in the process of turning processing, the fracture of the shaft part of the reason is that so
(3) Turning shaft fracture can also be by road conditions, temperature, and assembly (two shaft alignment is a straight line) factors have a close relationship.

Concerning the mechanical properties, the quenched material showed superior strength and ductility besides a less localized deformation at higher strains.
The mechanical properties of the DP steels are mainly attributed to their microstructure which consists of hard martensite islands (or in some instances bands) embedded in a ductile ferritic matrix.
Additional constituents found in DP steels are bainite, new or epitaxial ferrite and retained austenite where the amount of these constituents depends among other factors on the cooling rate of the heat treatment.

Previous research suggested that pore morphology and direction greatly affected bone ingrowth behavior [4, 5].
This method can be useful to fabricate porous implant materials possessing aligned pores and control the porous structure (e.g., pore size, porosity), which is one of the predominant factors for determining mechanical properties, such as Young’s modulus in particular.
In this study, porous structures of Ti-6Al-4V alloy with uniaxially and orderly aligned pores were fabricated using the EBM method for biomedical applications, and their microstructural and mechanical properties were evaluated.
For the evaluation of mechanical properties such as Young’s modulus and yield stress, compression tests were conducted using a mechanical testing machine (AG-X, Shimadzu) under the crosshead speed of 1.67 × 10−4/s.
The mechanical properties of such porous materials can be optimized or customized by changing the porous structure such as the grid spacing and wall thickness by using the EBM method.

Introduction A significant anisotropy of mechanical properties in cold-rolled duplex steels is not only the result of the specific morphology of ferrite-austenite structure after deformation (i.e. grain shape and phase arrangement) but also strongly depends on the crystallographic textures of the constituent phases [1, 2].
Thus the factors affecting a development and formation of the final rolling textures in ferritic-austenitic stainless steels are the subject of increasing interest [3÷8].
Among the important factors, which should be taken into account when analysing texture evolution upon coldrolling of duplex type steels are the initial orientations of both constituent phases after casting and subsequent thermo-mechanical treatment [3,7,8].
The important factor affecting the texture development is the specific band-like morphology of twophase structure, which reduces significant lattice rotations especially at higher deformations and restrains a development of typical rolling textures within the ferrite and austenite bands (Fig. 4a,b).
Some discontinuities in texture formation of constituent phases are apparently affected by strain partitioning between ferrite and austenite in the course of rolling.

While tool damage cannot be avoided, it can often be reduced if its failure mechanism and the factors controlling it are properly understood [4].
It has also been shown that HPC results in better surface integrity and lower compressive residual stress, which improves the properties of the machined work-piece [15].
In general, elements that affect chip shape include work-piece material properties, machining parameters and tool geometry [29].
But based on above analysis, nitrogen gas is another factor that affects chip shape of titanium alloys.
He found that there is a big difference and marked clearly on each of these properties before cooling and after.

Disscussion 3.1 S-N curve The factor of effect on S-N curve of isothermal fatigue of TiAl alloy is such as composition and microstructure of alloy, machining surface of samples, temperature and mechanical strain amplitude as well as strain rates which applied to the samples.
A great number of dislocations were found in the sample after IF tests at 500 oC (Fig.6a, 6b), stack fault piling up and dislocation blocked at the γ/α2 interfaces, the interaction between dislocations and stack faults within the more wider γ lamellar, dislocation kinking at the γ/α2 interfaces (Fig.6c, 6d), which all were important factors of leading to the hardening on the curve of cyclic strain-stress responding.

In the high temperature environment, this will lead to metal materials of all kinds of mechanical properties and its parameters change, at the same time cutting forming quality and tool wear with thermal stress changes.
Analysis does not consider heat convection, heat radiation and other affecting factors, that is to say will tool and chip contact as adiabatic process.
Thus it can be seen, the cutting edge area parameters affect processing temperature is a very big factor.
