The paper analyzes static stiffness of technological system machine tool - cutting tool - workpiece as one of factors affecting machined part accuracy.
Stiffness of technological system machine tool - cutting tool - workpiece is one of factors affecting final machined part dimensional and geometrical accuracy.
There are authors that analysed the complex mechanisms, relationships and requirements on performance of machine tools, sources of errors and they provided schemas named Machine tool structural “loop”, Machining error generating process, Factors affecting machined part accuracy, more in [1].
The schemas analyse and define the relations between individual factors.
To obtain moment of inertia of real end mill cross section, the software (Creo Parametric) and its function X Section Mass properties was used.

Paperboard used in this paper is anisotropic, and its mechanical properties include tensile strength and elongation.
According to the tensile properties shown in Table 2, the elongation in CD is about 1.5 times higher than that in MD.
And moisture is a vital factor influencing paperboard properties and deep drawing process.
Paperboard with high tensile strength, elongation and low basis weight has good deep drawing properties. 4.

The effect of nanoclay on mechanical properties were investigated by carrying out flexural and fracture toughness tests.
This reduction in mechanical properties for high clay loading were attributed to the increase of agglomeration and voids.
Mechanical Properties.
Flexural Properties.
It can be seen that both properties are affected in a similar fashion by clay addition.

It is important to evaluate the mechanical properties of copper foil to assess their reliability.
It is well known that the mechanical properties of metallic foil and film are different from those of bulk materials because of their unique microstructure.
However, the influence of microstructure of metallic foil on its mechanical properties is not clear because a lot of factors, such as foil thickness, grain size, specimen size, and loading condition, affect it.
After machining, heat treatment was conducted to adjust the grain diameter to 20 mm for each specimen to evaluate the influence of specimen thickness on their mechanical properties.
The mechanical properties of both specimens in a vacuum (SEM) agreed with those in air.

Mullite content affects the binding of friction modifier, it is contributed to the different properties of friction material
An aspect ratio of Cu fibers can be an important factor affecting the physical and thermal properties of the composite brake pad material.
The selection of binder depends upon the factors such as cost, application, material, manufacturing process etc.
But they did not possess the equitable mechanical properties.

The results show that oil volume per lubrication cycle, interval time per lubrication cycle and air pressure are three pacing factors that affect the temperature increase most significantly in ceramic motorized spindle with oil/air lubrication.
The Taguchi method is applied to analyze the effective factors.
Before determining the optimum lubrication conditions, the parameters must be identified, i.e., the effective factors which may affect the temperature increase.
Each of the four lubrication factors is designed with three levels, as shown in Table 1, because the influence of these factors on the results may vary nonlinearly.

The scale structure, microstructure, morphology and phase composition are
indicated as factors strongly affecting its growth mechanism.
Introduction Lifetime of the materials applied at high temperatures in aggressive gaseous atmospheres strongly depends on the properties of the formed reaction product and its compatibility with the substrate in terms of mechanical properties and on the interfacial product-substrate adhesion.
Scale growth mechanism is one of few factors substantially affecting materials properties during high temperature service exposures.

The combinations of these factors including high temperature, metallurgical alternations and plastic deformations, rather than the residual stress alone affect surface topography and surface integrity.
Eriksen [7] questioned the effectiveness of surface roughness on material’s mechanical strength properties.
The basic idea is: the data for mechanical properties given by material suppliers must be different from properties of machined components because the careful treatment of test specimens differs considerably from an ordinary industrial procedure.
Surface integrity factors Surface integrity is closely related with the functional performance of machined workpiece.

Fig. 6 presents the mechanical properties of composite joints FS welded using CSTPP tool.
Hence lower tensile properties were obtained at higher rotational speed.
Processing variables such as rotational speed and welding speed are the significant factors to be considered in joining of composite material to obtain defect free and good quality of joint.
