  • indicators of surface quality for machine working;
  • forces, vibrations, acoustic emission and temperature during difficult-to-machine materials cutting.

Our developments

The Scientific and Educational Center developes and uses methods for measuring the Modulus of elasticity, speed of sound, logarithmic decrement of vibrations of composite materials, as well as the strength under dynamic loading of small samples by means of Hopkinson-Kolsky measuring rods.

An automated unite based on a lathe was created, which is capable to measure the temperature in the cutting zone, the components of the cutting force, vibration parameters, acoustic emission signals during cutting, as well as the roughness and waviness of the processed surface.

Optimization of the technology of using diamond tool materials in the processing of copper, aluminum and titanium alloys, drilling of carbon and fiberglass with original drills made of diamond-hard alloy plates, and fine turning of non-ferrous alloys with diamond single crystals was carried out. Studies of the effect of cutting modes on the performance of cutters made of composites based on cubic boron nitride during fine turning of hardened and 15 steels were carried out.

The physical and mechanical properties of impact-resistant boron carbide ceramics were investigated.
