It can get from the analysis that the double-position structure and certain amount of interface are key factors to keep HSK high radial positioning accuracy and stiffness.
So it is necessary to analyze the contact stress and size to get how the amount of interference affects the radial position accuracy.
Fig 9 The measurement of standard radial stiffness Fig 10 The radial stiffness curve of HSK by measurement Conclusion The radial positioning accuracy and stiffness are two important factors concerning about the coupling performance of HSK tool system.

Stabilization incorporates the various methods to modify the properties of a soil to improve its mechanical properties.
Mechanical Properties The mechanical laboratory testing was conducted on the peat reinforced with various percentages of rubber chips (RC) at two different sizes and 5% cement content.
Compaction improves the mechanical properties.
The addition of cement induces a hydration process which reacts with water, thus affecting the dry density of the soil.
This is due to the fact that peat is a highly organic and tend to have poor mechanical properties.

Deposition rate change tendency schematic of the thin film of 1Cr18Ni9Ti The influence factors of thin film deposition rate are various.
Surface appearance of the thin film of 1Cr18Ni9Ti 15,000× Because 1Cr18Ni9Ti stainless steel is a kind of alloy material, the consistency of the composition between the film and the target is an important factor that affects the property of the film.
There are multiple factors of sputtering technology parameters can affect the adhesion between films and substrates.
Film adhesion is affected by the multiple factors of Van der Waals force, diffusion, mechanical lock, electrostatic attraction and chemical synthesis influence.
From the above analysis, it can be seen that the film adhesion is affected by the multiple factors of sputtering time, sputtering power density and target materials.

The dependence of the local flux on the entire specimen geometry and nonhomogeneity was considered by Larché and Cahn as a failure of local Fick's law and explained as an effect of non-local factors.
The Cu-Fe-Ni system was chosen because it is a single phase in a wide range of compositions, its thermodynamic properties are fairly well known [10] and because the tracer diffusivities in Cu-Fe-Ni alloys at 1273 K were measured [11].
The stress in the diffusion couple shown in Fig. 1 markedly affects the rate of the interdiffusion process.
Calphad denotes the Darken method with thermodynamic factor included, the Ideal alloy are computations when ai = ci.
The Young modulus significantly affects the process.

Since soil has been used as a construction material from the dawn of time, it`s unsuitable mechanical properties has been putting impediments to construction engineers to enhance its properties depending upon the required standards.
Among these factors the morphological (texture and structure) , and mineralogical composition of the material.
The properties of the fibers used in this study are summarized in Table 2.

The main aim of this paper is determined of properties, especially granulometry, of recycled silicon carbide waste and its possibility of using in new cementitious recipes.
Particle size influences many properties of particulate materials and is a valuable indicator of quality and performance.
Materials Filler used for cement mixtures, accounts for 70 to 80% of the volume of mixtures, is for its quality one of the decisive factors.
Conclusion Each recycled material has its own specific properties even if it has the same mineral origin.
The characteristic of fillers can affect concrete at the physical and chemical levels.

In developing soldered constructions (assemblies), the physical and mechanical properties of materials and material-based solders, the physical and chemical stability of solders, and their compatibility with coatings to be soldered were the crucial part to take into account [2–6].
These factors bring significant influences on the behaviors of products, such as magnetization, density, ductility, wear resistance, corrosion resistance, porosity, molecular structure, crystal properties, etc. [9].
The hydrogen evolution lead to the rise of bubble formation that often get incorporated in the crystal lattice, adversely affect the structure and properties of the metal being deposits by resulting in porous and spongy deposits[12], [14].
These results suggest that pH of the electrodeposition bath is closely associated with deposition properties such as average size of particles and density and compactness of resultant electrodeposited film.

Investigation on surface and biological properties of silver containing diamond like carbon films on polyethylene terephthalate film surface by hybrid reactive sputtering method.
The surface properties of DLC films are very important in biomedical applications; hence it is necessary to design the surface properties of the DLC films.
PET is one of the most important polymeric materials used in the biomedical field because of its excellent mechanical properties and moderate biocompatibility.
The silver particles are able to improve the mechanical properties such as micro hardness of the DLC films. 3.5 Hydrophilicity analysis: Contact angle results The hydrophilicity of the Ag-DLC films is analyzed by contact angle measurements using sessile drop method.
Hence the factors sp3, surface morphology and concentration of Ag are responsible for increasing the contact angle.
