This factor can significantly affect the performance of both the tool and the bearing units of milling machines, as well as the processing quality of the workpiece.
It should be noted that it is important to have a set of high level band-pass filters to identify the vibrations levels arising at the tooth frequencies and multiples thereof frequencies which characterize the defects, cutter wear process, affecting durability and processing quality of the equipment.
The choice of this material is based on its widespread application due to good machinability and good mechanical properties.
For vibrodiagnostics of the milling machine, it was decided to carry out an experiment with three varying factors (cutting width ae=const): rotational velocity n; cutting depth ap; feed s (Table 2).

This paper presents a conclusion drawn by adopting laser processing technology to form striated non-smooth surface of nodular cast iron and study the factors that affect the wear resistance at the normal temperature by means of single factor testing and orthogonal testing.
The parameters of laser processing are as belows: electric current 30A, velocity 0.5mm/s, frequency 16Hz, pulse width 20ms. 1.2 Experimental method The factors affecting wear mainly involve material surface and external environment.
The material surface factors include the hardness of test-piece, the shape and density of the geometric unit of non-smooth surface.
The single factor test is conducted on the factors affecting wear to find the major factors for orthogonal experiment and achieve the optimal processing conditions.

The crystal structure is one factor affecting the corrosion properties of metallic materials.
Therefore, the purpose of this study is to investigate the influence of refined grains and twinning on the corrosion properties of magnesium.
The crystallographic factors of the material have been demonstrated to exert a substantial influence on the corrosion properties of magnesium.
For confirmation that the areas related to those factors were corroded, an in situ observation experiment was conducted.
This finding indicates that the presence of twins has a deleterious effect on the corrosion properties of magnesium.

As is well known, the wear performance of a material can be influenced by many factors.
For example, microstructure, mechanical properties, test applied load, abrasive particle size, wear distance and impact energy, etc.
Among these factors, the microstructure and nature of the material are extremely important.
Effect of microstructure and mechanical properties on abrasive wear is different when the materials exposed to different wear condition [6-8].

Poly(ethylene-co-vinyl alcohol), a large molecule polymer was chosen to make the fibres for its biodegradable and biocompatible properties.
The thin sheets obtained were tested in uniaxial tension for their mechanical properties in view of the potential use as wound dressings.
Note that these factors are interlinked.
Mechanical properties under tensile loading were studied for potential use of the material as would dressings.

The uniaxial compressive mechanical properties of nanocrystalline Fe are simulated with a molecular dynamics technique and the analytical embedded-atom method.
Introduction Affected by external loading condition and the friction between the apparatus and sample surface, the mechanical properties tests of metals are often made through tension method experimentally.
In the computer simulation, there is no loading stress limitation and can exclude all kinds of influence factors.
The model parameters are determined by fitting the physical properties of α-Fe, such as cohesive energies, vacancy formation energy, and elastic constants.
The abnormal mechanical properties are attributed to the high fraction of grain boundary atoms, and the plastic deformation is mostly carried out through atomic sliding on grain boundary and grain rotation.

Besides, stirring conditions, forming and curing conditions together with the influence of curing conditions on autoclaved sludge bricks’ mechanical properties are discussed.
The brick’s mechanical properties, including compressive strength and flexural strength, are tested in light of the National Standard “Fly Ash Brick” (JC239-2001).
In light of the existing researches on autoclaved sludge brick, the factors affecting the properties of autoclaved sludge brick include the ratio of raw materials, stirring intensity, forming and curing condition and autoclave curing condition.
The choice of factors and levels is listed in Table 2.
The reasons are as follows: during the process of autoclave curing, the hydration reaction occurs fully between lime and fly ash, generating a lot of hydrated calcium silicate minerals, including C2SH (A), CSH (B) and tobermorite, and CSH (B) and tobermorite are very important factors to the physical and mechanical properties of bricks.

The viscoelastic properties of the PLA/pectin blends were assessed to determine their impact on printability and mechanical performance.
Mechanical properties, such as compressive strength, were analyzed to ensure the scaffolds could support cellular activities and tissue ingrowth.
Mechanical Properties: Compression Testing The compression strength of a scaffold is influenced by various factors, notably viscosity and strand width as illustrated in Figure 2a.
This is particularly relevant when considering the properties of pectin, known for its gel-forming abilities, which, when combined with PLA, can lead to a scaffold with improved mechanical properties [12,16,21].

There is no complete and reliable testing standard for mechanical properties of brazing joints.

Analysis of Factors Affecting Peel Performance Effect of base metal thickness on peeling performance.
There is not enough wetting in the brazing angle, which results in poor mechanical properties.
Considering the factors of crack initiation and expansion, it is more appropriate to select the two-layer brazing filler metal.
