The evolution of cutting force depends on material properties, machining parameters such as cutting speed, feed and depth of cut.
The cutting force is essentially corresponds to the product of feed, depth of cut and specific cutting pressure and further it depends on cutting tool geometry, cutting conditions, types of cutting tools and properties of workpiece materials [21, 22].
This phenomenon could be attributed from the effect of radius of cutting tool edge in machining and also the interactions between cutting tool edge configuration, machining conditions and the properties of work piece constitute behavior.
The performance factors are calculated with an accuracy of 10-2.

The magnetization curves were measured by a single sheet tester-type magnetic property analyzer.
Introduction Duplex stainless steels (DSS) represent a series of alloys characterized by high mechanical properties and corrosion resistance.
The properties of stainless steels can be studied by traditional microscopic, magnetic methods and modeling techniques as well [1, 2, 3, 4].
It was found that the substitution of Ni with a combination of Mn and N did not affect phase balance in LDSS [5].

Furthermore, many of the mineralized tissues formed by organisms have amazing mechanical properties [1,2].
However, the mechanical properties of Ca- Ps are far from being close to those of human bone, which limits their applications.
These materials combine a degradable behaviour with an interesting combination of mechanical properties [98,99,101].
These molecules may affect the surface properties of the materials by adsorbing before or simultaneously to the calcium-phosphate layer formation.
The factors that affect ion release from thin-film coatings include Ca-P chemistry, coating roughness, and extent of coating strain.

The experimental results demonstrated that the temperature of the substrate does not affect the chemical composition of the deposited thin films.
In our study of the bulk MAX phases of Cr2AlC- V2AlC solid solutions, we found their mechanical and electrical properties are superior to their end members[7].
In this study we will synthesize the (Cr,V)2AlC thin films and investigate the effects of deposition conditions, as well as the properties of the deposited films.
It is reasonable to conclude that, at least in this system, the substrate temperature does not affect the final chemical compositions of the deposited thin films.
Secondly, the gas phase scattering is an important factor that influences the composition of the thin film deposited, since some atoms, such as C, travels in the Ar gas in straight paths while the other atoms may be thermalized and experience sufficient collisions before reaching the target, which was concluded from the case of Ti2AlC film deposition.

The selection of appropriate mortar mixtures is an important research problem once four main factors should be considered in their design - durability, flexural resistance, compatibility and, consequently, economy.
In terms of physical properties, mortar samples were used for capillary water absorption determination – capillary coefficient in terms of initial capillary absorption velocity and the asymptotic value in terms of total capillary absorption [12, 13].
Lime-based mortars flow consistency seems to not be affected by the usage of waste fibers.
LF1, with 0,25% of waste fibers, presents one of the most well-adjusted mechanical behavior.

To describe the state of the material, the properties are determined at the very surface.
This indicates that the underlying assumptions regarding the scatter of the surface properties as well as their superposition over all finite elements are appropriate.
It needs to be investigated whether the ECM specimens with R = −1 are subjected to significant plastification, as this would affect the determination of R0w, 50% and vc
