In this study, cutting
stresses, residual stress and tool life are explicitly described as functions of tool geometries, cutting
speed, chip load, cutting fluid properties, interface tribological conditions, and the cutter/workpiece
material constants.
Therefore, the individual factors as well as the interrelated connections between these factors are deemed important.
The tool flank wear rate is estimated by considering the thermo mechanical responses of abrasion, adhesion, and diffusion wear mechanisms as functions of material properties, tool geometry, and cutting conditions.
For tool wear modelling, cutting velocity was seen to be the dominant factor for tool wear progression.
A slight change in one parameter will affect the other physical attributes of the machining process.

The orientation of the fiber and the fiber-matrix bond relationship are important factors that affect the performance of UHPFRC.
Fibers are incorporated in Ultra-High Performance Concrete (UHPC) matrix to enhance the fracture properties of the composite.
And the properties and performances of UHPFRC can be affected by fiber type, content, orientation and distribution [5, 6].

The impact of preparation parameters and the dosage of anti-fogging and anti-dropping masterbatch on the mechanical properties and non-dropping properties of the film has been investigated by versatile mechanical testing machine, atomic force microscope(AFM), contact angle tester, water bath acceleration method.
Results and Discussion The mechanical properties of greenhouse film is shown in table 1.
Mechanical properties of greenhouse film Group A B C D Tensile strength[Mpa] 23.346 22.011 21.600 24.501 Elongation at break[%] 901.58 901.01 882.41 1009.94 The results of mechanical properties testing shows that with the addition of anti-fogging and anti-dropping masterbatch, the mechanical properties of the film decreased, but the degree of the decrease is not big.
In consideration of the two factors, to add 10% of this masterbatch is the most appropriate.
In some occasions which demand less on the mechanical properties of the greenhouse film, the addition of anti-fogging and anti-dropping masterbatch can be increased properly.

They are related to the polymer properties and surface roughness of the etched
mold.
It is expected that the duplication properties can contribute to molding process of surface pattern in injection molding.
And, conventional CAE systems such as Moldflow and C-Mold can not support analysis of the surface pattern property, since it is influenced by many factors such as polymer types, molding conditions and roughness of the etched mold, and so on. [5, 6] In this paper, injection molding of the surface pattern is investigated experimentally for duplication property on polymer types; amorphous polymer, crystalline polymer.
It means the friction of mold surface affect the duplication property.
The duplication properties of surface pattern are affected with the thickness of specimen, roughness of the etched pattern, and types of polymeric materials substantially.

The main goal of this paper is to make the selection of optimal metalization procedures, group of filler materials and metalization technology definition, based on the results of structural and mechanical properties of samples, experimental model hardfacing.
Experimental research indicates a linear dependence of abrasive wear resistance and mechanical properties of materials.
Specifically, based on the mechanical properties, especially hardness can be predicted as behavior of metals in the conditions of wearing.
Microstructural components in proportion to its hardness, the relative share and distribution affect the level of resistance to wear. [2-4, 8] Based on previous research, the following factors can be concluded for the intensity of abrasive wearing affect: the nature and characteristics of the abrasive, aggressive working environment, the operating speed and load, and material properties of working parts, or their contact surfaces [2-4, 7, 8].

Negligible factors in bulk materials, such as grain-size effects, have proven inappropriate to be neglected for micro-forming processes.
The Procedure Mechanical properties analyses on thin sheet metal had received vast studies worldwide covering some popular engineering material [3].
Apart of determination of mechanical properties through uniaxial testing which was conducted on each strip, measurement of grain structure is also important because grain size does have an influence on the material mechanical properties [2-4].
This has resulted in a lesser grain density, which may be affecting its mechanical properties.
Discussions – Size Effect and Material Stress–Strain Relation Many investigations have been conducted elsewhere [3] and have shown that sheet metals of different grain sizes show different mechanical properties.
