While in the cutting process, particularly when the workpiece hardness is higher than HRC55, the tool is vulnerable to suffer the wear, resulting in the reduction of its durability[2].
Conclusions In order to improve tool life, reduce processing costs and improve processing efficiency, this paper aims at dealing with the relation between the axial force and the cutting parameters, thus a regression model of the axial cutting force based on the experimental data is established.

From the strain data can be seen in Figure 2, three measuring points in the initial curing concrete are generated compressive strain, which is due to thermal effect of hydration of cement, and concrete expansion due to heat generated, while the outer layer of concrete expansion has been constrained.
However the center point and the base of the measuring point are relatively slow cooling, with the reduction of swelling, as an result the compressive strain gradually decreases.

The intensity in white line in the case of sample 3B is minimum which may indicate the minimum iron oxide yield and the reduction into metallic Fe.
In order to quantify the amount of each phase in the samples, the linear combination fit were calculated using XANES data of standard reference materials.

Since acetic acid is one of the major components in bio-oil, it has often been used as a model compound of bio-oil and study of acetic acid can provide valuable data for hydrogen production from the real bio-oil.
By increasing WAMR, hydrogen and CO2 concentration could be increased along with a reduction in CO and CH4 concentration.

According to the relevant data, set the input rotation rate 477rpm and the power 90KW.
CONCLUTIONS This paper established the wheel edges of gear reducer, and a simulation model of a planet gear and supporting bearing is analyzed by the planetary gear damage percentage, bending stress, contact stress and Ann area coefficient, The results show that the simulation analysis, wheel edges all the reduction gear reducer to meet the required strength, and the bearing life is long, low damage.

The reduction of chipping during dicing, which is the ultra-precision sawing process of silicon wafer in the die form, is becoming more and more important, since the smallest chipping can cause damage to the circuit [3].
It shows the important of dicing process of silicon wafer as waveguide transfer mechanism for the data transfer in electronic device and other functionality.

Introduction
Since the past decades, incremental sheet metal forming has been investigated with a great attention due to its potential for the rapid prototyping of sheet metal parts in terms of flexibility, formability and cost reduction compared to conventional processes.
In this study, MINITAB 14 was used to statistically analyze the data [10].

Unfortunately, it is difficult to binarize WEM directly through applying most existing binarization algorithms which require the input data being the form of image.
One available solution is transforming WEM into the image form, which means the high dimensional equalization vector needs to be compressed into the one-dimensional form by an effective dimensionality-reduction method.

A serious, reliable assessment of FCG and residual life of a component can only be carried out on the basis of a sufficient set of experimental material data from both stable crack growth and threshold regions, whereas scatter has to be considered, too.
Load shedding method was used for pre-cracking, i.e. stepwise reduction of load range according to standard recommendations.
