In the production of net-shape parts, the challenge is a constant process behavior and product quality, even if the properties of the semi-finished parts are affected by uncertainty.
When using single stroke bulk metal forming processes like closed-die forging, the geometric properties of the product are strongly depending on the volume of the blank.
Apart from the influence factors described by [3, 4] the aim is to examine if the movement pattern has an influence as well.
The influencing factors are the infeed per revolution, the inclination angle and the movement pattern.
In terms of control theory, adjusting just one system variable without affecting the other is called decoupling.

Many studies have been done about the effects of various factors on the fatigue crack growth of γ-TiAl alloys.
For the mechanical properties of metals at room temperature, the grain size is finer, and the strength and hardness is higher, and the ductility and toughness as possible.
Based on the theoretical derivation, the mechanical properties of TiAl alloy under the same heat treatment is the same.
In order to find more TiAl alloys suitable for aerospace, it is meaningful to study the influence of different factors on fatigue crack growth.
Microstructure has vital influence on the material properties.

Plastics reinforced with fibers show the dependence of mechanical characteristics on linear dimensions - the scale factor [11-13], moreover, the significant influence of the technology of manufacturing and preparing a specimen on its mechanical characteristics is observed [14-17].
This phenomenon has been simulated by setting the degradation coefficient of material properties.

Deposition of polyaniline/silica nanocomposite coating on stainless steel; study of its corrosion properties M.
These materials possess electrical conductivity, electronic and optical properties such as metals while retaining processability and mechanical properties usually associated whit conventional insulating polymers.
In the present case, the barrier properties are improved no doubt due to the nano-size of the PANI–SiO2.
The nano-size additives are known to improve the barrier properties of polymers for diffusion of solvent/gases by a factor of 10 or even higher[15].

They were affected by some factors such as tool wear or change of tool geometry.
Some other factors such as diamond coating delamination and cutting vibrations may also cause unstable milling process and result surface damages, which need to be confirmed in further study.
This may be caused by the changes of tool tip geometry or some other factors such as cutting vibration.
