Among micro and mini manufacturing processes, micro forming has economical and ecological benefits due to high production rate, low material scrap rate, net shape production, and improved mechanical properties through work hardening.
The material used in this analysis is copper - zinc alloy with anisotropic properties.
There are multiple factors that affect the mini-part geometry during forming process as: blankholder force, punch rounding radius, and side wall angle.
There are many factors which affect springback, such as anisotropy of the material, shape of the final mini part, friction conditions and process parameters.
By varying the values of all factors simultaneously, a statistically validated estimate of the results for every possible combination of the factors is possible.

Effects of particle size and binding materials on shear strength were analyzed by comparing shear properties of undisturbed and remolded soils with the same dry density, water content and vertical loads.
The results show that all the angle of internal friction () and most of soil cohesion () of undisturbed soils are bigger than that of remolded soils; The final shearing stress also comply with the law above; The main factors affecting shear strength are soil particle size and binding materials.
Other soil physical properties were tested: soil bulk density-core cutter method (100 cm3), natural soil water content-Time Domain Reflector (TDR).
Loose soils also were taken from the land use types above, dried in wind, and sifted through 2 mm for further measurement of soil physical properties and mechanical behaviors.
It is also the main factor influencing the cohesion.
