In this paper, cutting speed, feed per tooth, axial depth of cut and radial depth of cut were set as control factors with three levels respectively and cutting force was set as response factor.
The significant factors for the cutting force was determined by Taugchi's experiment and range analysis.

The static mechanical properties of the specimens were evaluated by performing tensile tests.
There are two factors that will act directly proportional to any of these costs: the size of the powder particle and the build rate.
The heat treatment consists of two stages, one at 530 ºC for stress relief and the second at 830 ºC for increasing the mechanical properties.
For this reason, the roughness, mechanical properties and productivity achieved in this study are considered adequate.
These process parameters have made it possible to manufacture parts with different volumes and shape factors.

From the experiment results, it was found that the cutting direction was an important factor affected to the bent-up angle and cutting load response of the nylon film.
In the laminated material cutting, problems that affect the product quality of the cutting worksheet are caused by many mechanical conditions for making the cutting process such as the tip thickness, mechanical properties of underlay.
Moreover, the mechanical combination between the cutting tip and cutting sheet is played important factors, especially the mechanical properties of the laminated sheet is the primary factor.
Due to the different material properties of these layers, troubles sometimes occurs with unstable cutting phenomena.
Mechanical properties of polycarbonate underlay and nylon film.

The mechanical properties are better when the grain boundary particles are dissolved and the Cu content in the matrix is increased.
Alloy development experiments carried out at the University of Sheffield on A201 alloy have shown that the alloy behaves well under thixotropic conditions and develops high mechanical properties after appropriate heat treatment.
In semisolid forming the best mechanical properties are exhibited by small grain size, shape factors above 0.6-0.7 and homogeneous globular size of the primary phase.
All samples were compared for liquid fractions and changes in microstructure; average grain size and shape factors are also compared.
Hence, if repeatability and consistency of mechanical properties of the final product is very important in an application, then MHD would appear to be a better but costlier feedstock production route.

Due to their cost-effectiveness and good mechanical properties, they are often used for transportation over long distances [3].
Tensile test properties for SA 312 type 304 Stainless Steel [25].
Elastic and thermal properties for different materials [26].
For comparison, the same dimensions and mechanical properties as those used by Benziane et al. [5] were considered.
This requires adequate mechanical properties, such as toughness [17].

In addition to residual stress, there are other factors acting important roles to the warpage.
Warpage is an integrated reflection of several deformations caused by multi-factors.
So its capability to resist deformation caused by outside factors will become weak.
The logic relationships of many influence factors were clarified.

The models of QTF were introduced in two types: a mechanical model and an electrical model.
Quartz Tuning Fork (QTF) The basic principle of the tuning fork [6-9] is well known to musicians: two prongs connected at one end make a resonator whose resonance frequency is defined by the properties of the material from which it is made and by its geometry.
The unique property of quartz resonators is such a huge equivalent inductance in a tiny volume [13].
The mechanical and electrical models of a tuning fork oscillator [12].
The Q factor adjusting of the QTF strongly affects to phase of output signal.

One of such tasks is the directed change of physical and mechanical properties of a surface of an initial product that provides possibility of its operation in the specified conditions.
The mechanical properties of the coatings and the glass substrates were measured using the NanoHardnessTester (CSM Instruments, Switzerland) under a load 20 mN.
The results of investigation of the mechanical properties of the coatings Al-Si-N formed by impulse magnetron sputtering are shown in Fig 3.
Researches of mechanical properties of glasses with Al-Si-N coatings showed that they have higher hardness and coefficient of elastic recovery in comparison with those for quartz glass without coatings.
The main factors affecting the mechanical properties are the crystallization of AlN and α-Si3N4 nanophases and the presence of high residual stresses in the II-AlSiN coating, due to the formation of a columnar structure.

Based on this study, the PEI, PC, and KCl inhibitors were found to be compatible with the drilling fluid as their interactions affected the optical properties but not the physical state.
Additionally, KCl has been found to improve the mechanical properties of shale samples, increasing their compressive strength and elastic modulus while decreasing their Poisson’s ratio [15].
This cation exchange can affect the surface charge, influencing the rheological properties [13], [14].

This factor reflects not only the comprehensive mechanical properties of copper materials for the production of the copper-cylinder, but also the processing operation and heat treatment which influence comprehensive performance of copper-cylinder.
Due to solid mechanical properties of copper-cylinder relates to temperature, when the temperature in which the standard copper-cylinder is used is different from the temperature in which the selection test is operated, this is bound to introduce the influence of temperature on the accuracy of pressure measuring.
The factors that affect the uncertainty of height measuring of copper-cylinder can mainly be divided into four categories
Systematically analysis measuring uncertainty factors that affects the standard copper-cylinder.
Primary pressure standard, height measuring of copper-cylinder, inconsistent individual deformation of standard copper-cylinder, inconsistent pressure sensitivity and the influence of temperature are five main factors that affect the measuring uncertainty of standard copper-cylinder.
