Since diamond tools possess excellent mechanical properties such as extreme hardness, lower frictional coefficient, they can achieve very sharp cutting edges, which are crucial for machining precision components [7,8].
In some researches, tool path length has been found to be a major influencing factor to the total machining time.
Tools wear is also a very important factor as small tool wear may lead to significant degradation of surface quality.
Surface roughness of optical surface is a key factor, which affects the dispersion of lens.
quality and form accuracy are affected by machining parameters.

These regions may have less advantageous mechanical properties; nevertheless they can serve as lubricant in the wearing process.
Experimental results Due to the numerous factors influencing the behaviour of the tribological system the evaluation of tribological test data supposes a very careful treatment.
SiC, complex oxides, etc.) are assumed to be created during heat treatment that caused significantly different properties (HV, E) in closely neighbouring areas of the specimens.

Introduction At present, the general area, buildings, schools, industrial and mining enterprises generally realized the water, electricity, gas, heat divided metering mode, table are mostly located in the house, the general need special meter reading personnel into people's homes, this way to the residents of inconvenience and interference greatly, even has the security hidden danger, in terms of management, there are low efficiency, manpower and material resources, human factors, management and many other issues.
Reading through a series of products, can meet the needs of different levels, such as the simple meter reading in households displaying, wired networking reading, wireless networking reading etc., to choose according to the actual situation, can meet the property management, industry management, school students in water and electricity management, industrial and mining enterprises staff management and other kinds of needs. 3.
There are many factors affecting the accuracy of meter reading, there are three main factors, one is the sensor element, meter counting on sensor can accurately transfer metering pulse metering, otherwise the result is not accurate, this is reflected in the metering especially.
Second is the anti jamming performance of products, because the pulse acquisition circuit is long, so inevitably there will be some interference exists, if the meter reading device cannot shield the interference, will inevitably affect the accuracy of meter reading.

Introduction The use of Powder Metallurgy (P/M) aims to obtain orthopedic implants with almost net-shaping and adequate mechanical properties and surface porosity.
This TNZT has excellent non-toxic components with good mechanical properties and workability [5, 6, 7].

In this way, the analyte in all air holes is detected which can be affected through the evanescent field.
The energy overlap factor is defined as the percentage of energy propagating in the six big holes with respect to total mode energy.
The energy overlap factor is 0.00389 when holes are filled with air, and that is 0.0121 when holes are filled with water.
The optical properties of the PCF has been studied and some future design also been proposed especially on the biosensing performance, which can potentially operate on biochemical detecting applications and is useful for improving higher sensitivity.

It is the functional liquid material which exhibit normal liquid behavior coupled with magnetic properties.
Currently, viscosity characteristics of the ferrofluid reflect its rheological properties which are very useful and can be applied to many applications.
Researchers believe that the factors influencing the viscosity of ferrofluid are pH, surfactant, solid content, particle size and temperature.
Temperature model correlated with change of the behavior of ferrofluid was build and it was strongly shown that the temperature is one of the factors that change the viscosity.
In our opinion, thickness of the coating layer was increased with the increasing of oleic acid and for that reason the ferrofluid properties are affected.

Introduction Owing to its high melting point, high hardness, good toughness and stable chemical properties, the VN coating has a very wide range of applications and long-term prospects[1].
The Chinese Geyang Li’s research group creates a series of nano-multilayer of VN/SiO2[6] and AlN/VN[7] in the multi-target sputtering instrument, and studies their microstructures, mechanical and antiwear properties using the transmission electron microscope, microhardness tester and precise dimple grinder.
It can clearly be seen that the best process parameter can’t be reoccurred accurately and quantitatively because of many random factors.
It indicates that VN is a conductor with good metal properties.
As the distribution of the DOS of Si atoms is very uniform and relatively lower, the distribution trend of total DOS was less affected.

There are various factors influencing the MIM process.
The selection of appropriate powder and binder system, mixing of the powder and the binder system and its viscosity will affect the product.
This study will focus on what are the characterization and rheological properties of the stainless steel 316L based feedstock.

Another physical property is the high crystallinity index of NCC (nanocrystalline cellulose), which is an essential factor for the increased mechanical strength when applied as reinforcement or filler to nanocomposite films and nano-membranes with PVA (Polyvinyl Alcohol) matrix [7, 8].
The main goal of this work focus on the morphological and physical properties of NCC.
The change of band located at 1630 cm-1 to 1690 cm-1 was shows hydrophilicity properties.
The crystallinity index affects the mechanical strength of the composite when used as a reinforcement in the polymer matrix.
