It affects the blade cooling, thus affects the tool's durability.
Under the same tool material conditions, the values of cutting speed, feed and depth ​​are not determined by one factor, the ceramic processing methods, processing requirements and parts material properties etc should be considered, to get the optimized best value.
Feed is the main factors to the parts surface roughness, smaller feed must be selected to improve the surface quality [8].
Cutting speed is the main factor to affect the machining performances.

Slurry preparation is of paramount importance in chemical mechanical planarization (CMP) process.
It couples the combination effects of chemical and mechanical ones.
The rheological properties of polishing slurries affect the material removal ratio (MRR) and surface quality of the wafer.
The slurry characteristics, such as the solid particle size, the particle hardness and concentration, coupling with some other factors, for instance, the slurry viscosity, the dispersant, the lubricant etc., have important influences on the reduction of the surface roughness Ra, the waviness Wa, scratches, pits, etc.

By Combining Taguchi method and injection molding simulation software – Moldflow, this paper studied FBGA and PBGA warpage deformation in the POP, setted four design factors, such as the mold temperature, melt temperature, injection pressure and injection time , find out the minimum warpage combination of design and critical design factors affecting the warpage.
Select four factors as the main parameters that affecting warpage, the mold temperature as A, the melt temperature as B, injection pressure as C and the injection time as D, arrange the orthogonal experiment refer to the orthogonal table L9 (34), table 1 is the level table for the selected factors.

Finally, the change of the stress intensity factors along the crack front was investigated based on simulation results.
The global mesh is not affected by the changing of local mesh size.
Improvement need to be made for simulation since Paris coefficient C, initial crack length and other material properties cannot be treated deterministically.

Rolling temperature is an important factor affecting mechanical properties of hot rolled strip significantly.
Introduction Rolling temperature plays a critical role in mechanical properties of hot rolled strip, and higher precision control of coiling temperature is highly related with good material properties.
Control of temperature during cooling is essential for achieving desired mechanical and metallurgical properties of steel [1].

In order to study the effect of these factors on the forming properties and thickness distribution of molding bottle, the article builds the physical model and finite element model of PET bottle’s stretch blow molding process, and simulates stretch blow molding process by using POLYFLOW software for analyzing the thickness distribution of molding bottle.
There are many influencing factors in blowing process, such as the velocity of stretching rod, pre-blowing pressure and inflation pressure.
If a large number of entity experiments should be depended, there exists a lot of blindness due to many influence factors in the blowing process.
It can more comprehensively describe the behavior of PET materials under high elastic state of stress-strain, especially the stress relaxation properties of materials.
The mentioned conditions are unfavourable for the overall mechanical properties of the bottle.

It is believed that microstructural features such as amorphous phase, grain boundary, secondary phase and intergranular pores contribute significant additional magnetic anisotropy and demagnetizing fields, thus affecting the initial permeability accordingly.
However previous literatures focused more on the effect of the composition-dependent-magnetic properties as compared to that of microstructure-dependent-magnetic properties of ferrites [2, 3].
The wide use of these materials and the general believe that their preparation conditions would affect their physical properties have motivated us to study the effect of sintering temperature on the evolving magnetic and thermo-magnetic behaviour of YIG.
In fact, resistivity is a result of the combined influence of several factors such as crystal structure perfection, grain size, microstructural homogeneity, and Fe2+ ion concentration [19].
