Based on all above, through the experiment the cold precision forging forming lawswas discussed, and according to the laws, the better mould structures were designed, in the end the aimed forming effect was gained.
On the basis of material mechanical test and forming limit analysis,the metal flow of the dangerous parts in trunk lid inner panel during the stamping process are studied by grid strain analysis technique,meanwhile the forming effects of two steel sheet are evaluated.
Investigation shows that nonedie explosive forming is the most effective manufacturing method of such parts,having the advantages of good forming results,high dimensional accuracy and simplicity of the process,thus exploring a new forming method for the spherical parts.
The differences of forming results between circular scanning and linear scanning and the influences of sheet metal geometry on forming effectness had been discussed. During the experiments, sector, ring sector and rectangle mild steel sheets with thickness of 0.8mm served as workpieces.
Objective To investigate the shaping effects of three nickel titanium rotary instruments on preparing curved canals in posterior teeth Methods 64 curved mesial canals of extracted lower molars, embedded in the Branmante models, were randomly assigned to four groups: ①Flexofile;
Its environment-forming effect manifests itself most strongly in the phytogenic field of living trees, where edaphic conditions similar to those in primary larch forests are formed within ten years after the fire.
- The apical cells show their tubuli forming effect only if they are in immediate cell contact to the imaginal cells; on the other hand it is not necessary for the tubuli forming cells to be in connection with the reservoir.
The molar ratio of 12HSA/12HS-Na for obtaining optimal gel forming effect was 100:1.
This is caused by the directed structure-forming effect of the zinc ions (ionotropic effect).
The forming effect in type B samples is compared with the forming effect in the conventional MIM sandwich structure (type A).
It takes a socio-political perspective on understanding the shaping effects of spatial arrangements on work practices, and seeks to identify some of the key CSCW issues that can be addressed in spatial terms.
Pulse shaping effects in Q-switched laser oscillators
How a child's genetic endowment is expressed will depend on the shaping effects and opportunities of the environment and nurture she experiences.
In the traditional adaptive beamforming model proposed by widrow there are K elements and KL weight coefficients. It is necessary that each of KL weight coefficients are iterated in every sample period.
A clinical analysis of 104 cases of malignant tumor in eyelid is reported. Meibomian gland carcinoma accounted from 44.2%, basal cell carcinoma, 42.3% in the 104 cases. Other cases were squamous epithelial carcinoma and malignant melanoma etc. Meibomian gland carcinoma is highly malignant.
