In a milling operation there are many factors that can affect the cutting force.
In this paper these are selected as design factors while other parameters have been assumed to be constant over the experimental domain.
The experimental results are analyzed with analysis of variance, which is used for identifying the factors and the experimental errors significantly affecting the performance measures.

The use of the homologous temperature T/Tm makes it possible to compare under corresponding conditions a number of the physical properties of crystalline materials determined by, for example, the self-diffusion phenomenon, but not the mechanical properties of crystals with different types of interatomic bonding and different crystalline structures.

This seems to occur because real contact area between specimen and mating ball was affected by the specimen hardness.
Introduction It is well-known that wear is a phenomenon affected by surface properties and can be repressed according to the hardening of a surface [1].
One of the advantages using the induction-hardening method is in that it can harden just a part of a surface without affecting the inside of the material.
Then, the ball-on-disk wear test was performed to determine the changes in the wear properties of SPS5 steel according to the induction-hardening treatment.
That is, the actual surface of contact, which is a factor that greatly affects wear properties, cannot be increased over a certain level and thus the coefficient of friction decreases.

Introduction The interfaces between carbon fiber and polymeric matrices in composite play an important role in controlling some of the mechanical properties of composites [1].
The sizing layer as the additional phase drastically affects the final mechanical properties of composites.
The effect of emulsion type sizing agents on processability of carbon fiber and mechanical properties of carbon fiber/resin composites were investigated.
To obtain stable emulsion，the content of emulsifiers and other factors must be adjusted when the resin ratio is various.
But if the sizing rate is high, not only it is a waste of materials and increases costs, but also thick sizing layer may affect the interfacial properties of composites.

Considering aerodynamics, structural mechanics, artistic style and some other factors, profile generally needs to be bent into certain curvature [2-4] and the bending quality becomes a key technology which influences assembly accuracy and service life of modern cars and aircrafts, directly relating to the research development and guarantee of device performance.
The A6N01S-T5 mechanical properties are shown in Table 1 and the section of given profile in Fig.1.

Effects of Bending Radius on the Forming Quality Bending radius is another important parameter affecting the accuracy of shape.
Springback is another key factor affecting the forming accuracy and the research of springback has drawn a number of conclusions [7-8].

SEM images of coating cross sections are presented in Fig. 2, mechanical properties of the coatings are summarized in table 3.
Table 3: Mechanical properties of HVOLF (K2) sprayed coatings.
The stress distribution in the coating/substrate interface is a factor which affects the coating adhesion.
Consequently coating properties are strongly affected by this circumstance.
High Velocity Suspension Flame Spraying of nano oxide (n-Al2O3, n-TiO2/TiC, n-Cr2O3) containing suspensions leads to fine structured coatings with improved mechanical properties.

It depends on the TPU's crystalline and products of size and many other factors.
The existence of internal stress in products will drop the regular mechanical properties, surface crazing or even deformation and cracking during the storage and use.
Annealing not only could eliminate the internal stress, but also may enhance the mechanical properties.
The above factors, select project-level experimental thermoplastic polyurethane elastomer as the main material, ensure dimensions and performance meet the preparation requirements.
e) Heat treatment Research found that in 110～130℃ the thermodynamic properties of TPU has obviously changed.

Flexible pipes are constructed in a layer structure in which each layer adds specific properties to the pipe such as; collapse strength, fluid integrity, tensile strength etc. [1].
The objective is to find the influential factors by means of production testing and FEA.
Roll forming has been successfully modelled in literature [4-6], but the carcass winding process is not easily idealized because of several factors that affect profile deformation that are not easily accounted for.
The observations suggest that tongue height and inlet angle with respect to the mandrel is affecting the QL deformation.
Mandrel size related factors such as profile pitch angle and entry angle are expected to affect dividing point movement - also through increased profile strains.

Based on the multi-phase hydration dynamic model, taking into account the factors such as chemical composition of cement, curing temperature, water-cement ratio, the final hydration degree and fineness of cement, a theoretical hydration kinetics equation is established in this paper.
Cement hydration model Influence factors of cement hydration kinetics include the chemical composition of cement, the water-cement ratio, cement fineness, curing temperature, etc.

In addition, the key factors of influence on water-absorbency including the amount of activated carbon and formaldehyde as well as the concentration of sulphuric acid have been discussed.
Poly (vinyl alcohol), a non-toxic water-soluble synthetic polymer, has a wide commercial application due to its good physical and chemical properties.
Therefore, it is necessary to convert PVA into a completely insoluble material with high mechanical properties.
