Abstract

This article is devoted to theoretical research in the field of vibrational destruction of materials in order to find ways to increase the wear resistance of wood-cutting milling tools. When processing wood and wood-based materials at high speeds, the use of vibration cutting makes it possible to change the conditions for the interaction of the "tool-work material" system, which opens up new opportunities for the use of various hardening tool technologies based solely on the creation of wear-resistant coatings.

The use of vibration cutting in the process of wood processing on CNC woodworking equipment allows you to influence the dynamics of the wood cutting process and has a positive effect on the possibility of using tool materials with low impact strength in the manufacture of wood cutting tools.

The theoretical studies carried out have shown that vibrations caused by the cutting process with the optimal frequency and amplitude of oscillations make it possible to improve the quality indicators of the process of mechanical processing by milling by adapting to the conditions for creating destructive stresses in the cutting zone. This will reduce the energy intensity of the processing process and increase the technological durability of the cutting tool, using various hardening technologies.
