The machinability of a work piece material depends on its mechanical properties and fracture behavior.
The properties of workpiece materials are shown in Table 2.
Final Equations in Terms of Actual Significant Factors are: MRR (Y1) = 57.26195 -1.55684 *A-0.10090*B+0.93635*C+0.019149*A2 ± 0.66 …
(2) The main significant factors affecting the value of the MRR are the power rating, grit size and slurry concentration.
(3) There is only one significant factor i.e. grit size affecting the value of SR (4) The material removal rate increases as the grain size increases.

However, only a few studies have examined its effects on the mechanical properties of a matrix when combined.
While the antibacterial properties of AgNO₃ are widely recognized and utilized, its potential impact on mechanical properties, especially in PLA, remains largely unexplored.
This discrepancy was most likely due to the geometric features of the specimens affecting the deformation mode.

Thus, the tribological properties of self-lubricating spherical plain bearing are the key factors affecting its life and performance.
Table1 The material properties of different spherical plain bearings Numbering Material of inner ring Material of outer ring bearing liner Bonding glue GCr15 20steel PTFE fibre woven AB brand glue GCr15 GCr15 PTFE fibre woven 801 brand glue GCr15 GCr15 PTFE fibre woven AB brand glue Test apparatus.
In order to reveal the differences of friction and wear properties among the three kinds of bearings with PTFE woven liners under the same conditions, SEM of frictional surfaces of three kinds of spherical plain bearings with PTFE woven liner are compared.
Conclusions Under the experimental conditions, the bearing I shows good tribological properties at the higher load (load ≥ 6kN) and suitable working in this condition, and the bearing Ⅱshows better performance, stability and good wear resistance but the anti wear property of bearing Ⅱ is little worse than that of bearings I.

Biodegradable is the ability of a material to be chemically decomposed or degrade into compounds under the influence of biological factors.
Biodegradable implant must be absorbed gradually, maintaining mechanical properties until they are no longer needed and then to be absorbed without leaving remaining compounds in the body [2].
Addition of Ca in a magnesium alloy will lead to grain refining, thereby improving the rate of corrosion and mechanical properties of the alloy [6,7,8].
Mechanical properties and corrosion rate of Mg-Ca alloys are influenced by the calcium content.
Especially the magnesium alloy Mg1Ca alloy showed good results related to the mechanical properties and corrosion rate [9,10,11].

Strength, evenness, hairiness and other properties of the low twist yarns were also investigated.
Fiber composition, cross-sectional shape, size, buckling extent, and spatial distribution are important factors to affect the yarn luster [5].
Due to reversed twist, cotton fiber in the roving yarn gets rid of the shackles of twist, retains the original bending and excellent convolution properties.

Liu et al. [10] studied the effect of skin effect on Micro-EDM, and argued discharge energy difference caused by skin effect was an important factor of electrode wear.
Due to electrode wear affected by various factors, it is difficult to use a single factor method to accurately describe its change trend.
Many factors, such as skin effect, edge electric field concentration and debris, are studied by COMSOL Multiphysics simulation software in this paper.
In a period of time, the distribution of discharge points concentrated in certain areas since discharge was affected by some factors including electric field centralization of rim, skin effect and debris distribution.
Changes in material properties of electrode in its rim and side can improve the accuracy of Micro-EDM.

Moreover, sheet metal material's anisotropic properties, as well as blank positioning, affect the forming process greatly.

Optical communication with its high speed, wide band, large capacity, low loss and other advantages, has become one of the most important factors of traffic growth.
To a certain extent, affected the reliability of optical fiber connector, optical transmission system and the performance.
Because the ceramic materials and quartz fiber thermal compatibility good, stable physical and chemical properties, therefore, the main development of the industry with the diameter of 2.5mm ceramic fiber connector ferrule as the core device.
The mechanical system is consisted four parts.
Imported linear guide rail assure the mechanical system runs in high precision and more stability.

In the process of tunnel construction, surrounding rock stress will redistribute, the vault and the two groups will generate displacement gradually over time, and displacement is a function of time, so the displacement at different time form a time series, but the time series is influenced by various factors on site, thus, it is not an equal interval series, use the previously described treatment methods: changing interval into equal interval time series, and handle the abnormal values, after these processes, you can form a distance time series: (3) Where: are the parameters of affecting the law of the vault and two groups’ displacement, expresses time.
If All the parameters and functions which affect the law of the vault and two groups displacement can be found, then the function can be directly used on the displacement time series prediction of the tunnel vault and two groups, however, the factors affecting the displacement of the tunnel crown and two groups can not accurately determined, and this function does not exist an explicit expression.
The good property of neural network can approximate any non-linear systems in any precision, which can effectively simulate the displacement timing changes of the tunnel crown and two groups.
There are so many factors influencing crown subsidence and the convergence of two groups, mainly containing depth, rock type, rock mechanical properties, surrounding rock structure, tectonic stress, time and forms of initial support, tunnel boring method, and so on.
Many factors are difficult to accurately measure, so it should not be directly as the input of neural network.
