The soil that is a geological material is easy to be disturbed in the sampling process, which results in large discrepancy between the laboratory test value and the actual value of soil parameters.

The mechanical properties of the workpiece and tool materials were set by choosing the appropriate metal from the library of materials available in the software package for steel 45 (HB 210 MPa) (Fig.4).
For this, the program has a choice of several sets of material properties data that can be modeled and analyzed: • Plastic properties of materials • Elastic properties of materials • Thermal processing data • Diffusion data • Grain growth or recrystallization model • Data on the hardness of materials • Material fragility data These parameters make it possible to specify the required output values ​​of the simulation, which increases the accuracy of the obtained data and reduces the time of their calculation.
However, the mechanism of wear here is determined by the seizure bridges, which arise when the contacting pair approaches, when the pressure exceeds the elastic limit of one or both materials.

In the case of conventional analysis, the polycrystalline materials should be considered continuous and isotropic, while in the case of nanometric cutting the materials should be considered as being composed of multidirectional single crystal grains and anisotropy.
These results justified that the effect of crystallographic orientation of crystal materials exerts a great influence on the chip formation mechanism in nanometric machining process.
As most engineering materials are polycrystalline, microcutting force variation can’t be avoided.
However, the crystallographic nature of cutting force variation can be minimized by the proper choice of substrate materials and machining process.
