This work is devoted to creation of static atomic model of two surfaces contact during electric diamond
grinding: single-points diamond and material grinded are among them. In the heart of the work there are issues of
computerized visualization of these surfaces on the molecular level, since traditional mathematical description does not
give sufficient visualization to demonstrate some aspects of the atomic tribology of metal cutting as the simultaneously
occurring processes, by their physical nature, are different. And in the electric diamond grinding effect combains
several processes simultaneously: mechanical, electrical and electrochemical. So the simultion technique proposed by
the authors is still the only way to see what happens at the atomic level,when the single-point diamond for material
cutting is applied.
Design package Blender© is not only a professional package for creating three-sizeal computer
graphics, as it is the best free-of-chaghe software.
The programming package includes functionality unit that allows to manipulate multiple systems
particles, wherein the particles are, as a rule, limited only by the computer hardware capacity. Modern
processors equipped with this programme successfully process up one million of particles, the amount
equals about 50 cubic micrometers. This amount (Fig. 1) of particles is quite advisable for the molecular
dynamic simulating [1 – 5].

The particles in the programme Blender© are not the polygon objects used for traditional three-sizeal
modeling. The particle is just a point (coordinate) in three-sizeal virtual space and has a radius similar to the
radius of the ion or electron cloud. This radius is used to count the other particles interaction [5]. However,
for the better understanding participle-to-particile interaction they may be displayed in the form of any
polygonal object, and this factor doesn’t influence on the interatomic interaction.
In the programme Blender© there is integrated physical engine Bullet Physics Library© allowing to
simulate simple physical processes, such as the global gravity and collisions between objects and particles.
