And the axial cutting feed is the core factor that affects the milling force.
Introduction Titanium alloy is widely used in the fields of aviation, aerospace and automobile industries for its excellent properties such as high specific strength, high heat intensity, and corrosion resistance and so on.
To investigate the influences of milling parameters in UVA milling on machining accuracy of titanium alloy thin-walled parts, L16 orthogonal experiments with 5 factors and 4 levels were designed and conducted.
Selections of factor and level are listed in Table 2.

Further step, effect of pouring temperature on microstructures and tensile properties of castings was researched in the introduced process.
Microstructures and mechanical properties of rheo-diecasting samples are investigated.
It is mainly caused by two factors, one is heat loss of slurry during processing as mentioned above, the other is the sensitivity of solid fraction to temperature changes which becomes very high below 570 ºC[11,12] .
With the aim to analyze the factors affecting solid volume fraction, the number of primary particles per unit area is selected to represent the density of primary particles because of randomly observed area.

Warpage is an important factor affecting on product quality.
Liao et al. [4] indicated that the optimal process conditions were different for the shrinkage and the warpage because during the injection process, the mechanisms affecting shrinkage or warpage were different.
In order to determine the influence and relative importance of the factors, ANOVA was performed.
The contribution of each factor to the warpge and volumetric shrinkage of control factors can be determined by performing analysis of variance (ANOVA) based on Eqs. (4) - (7).
However, most previous researches on warpage concluded that the packing pressure as the most significant parameter [13, 20], which probably due to different material properties and geometry effect.

Mechanical properties results indicated that a chromites mold under low vacuum condition has the optimal value.
It was caused that changing of thermophysical properties of mould affected changing of heat transfer process between casting and mold.

Real composite components are usually affected by the presence of a large number of voids and defects, which cannot be reproduced in numerical models; this leads to a variability of the mechanical properties of materials, with particular reference to elastic moduli and density.
An increasing in the damage detection capability could improve significantly the design philosophy, resulting in lower safety factors.
Their presence enlarges the variability range of the materials mechanical properties, with reference special focus on elastic moduli and density.
Material properties.
In this paper a DoE analysis has been carried out to understand the effects of the variability affecting the composite material properties on the propagation mechanisms of guided waves.

Timber is one of the most used materials for roofing of ice arena because of its very good mechanical properties and low weight.
Newly developed mathematical and physical model using CFD simulation is used for simulation of hygrothermal stress in chosen part of the ice arena roof construction, which substantially affects quality, utility properties and life time of timber roof components.
Not only the long-term action of liquid condensed water, but also the increased air humidity in the surrounding of cooled timber constructions are the cause of a decrease in biological resistance and a deterioration of the mechanical properties of wood mass.
To assess long-term risks of wood degradation and changes in mechanical properties due to an increased moisture, it was necessary to create a simplified 2D model for solving time-steady heat and humidity transfer in timber constructions taking the ice rink radiation into account.
In publication [4] it is stated that for wood with a moisture content between 8% and 20% an approximately linear dependence between moisture and mechanical properties can be considered.

In order to decrease the packaging thermal stress, correlations of packaging thermal stress with the material properties, curing temperature and geometrical size of adhesive layers of adhesive materials were discussed.
The simulation results show that the Young’s modulus, thermal expansion coefficient, curing temperature and geometrical sizes of adhesive layers are important influencing factors for packaging thermal stress and the warpage of the chip.
As one of the key processes in packaging, SMT usually generates thermal stress which is one of the primary factors affecting the accelerometer’s reliability and availability.
Hence, the influencing factors for the reliability of packaging and the performance of the device, such as thermal mismatch, stress, strains during the SMT process, should be analyzed and predicted before packaging.
In this paper, the finite element analysis method has been used to reveal the relations among properties of the adhesive material, its curing temperature, geometric parameters of adhesive layers, thermal stress and resonance frequency of the resonator, so as to research the effect of the SMT process on this accelerometer.
