The article deals with the problem of the development of materials science. The author pays special attention to the issue of the development of new materials, which is associated with the increasing requirements to boost the level of their physical, chemical, technological and operational properties and the creation of technologies for obtaining and production. The idea is substantiated that the development and production of instrumental materials is of particular scientific and practical interest. It is known that in mechanical engineering and other industries, labor productivity and the quality of machining of machine parts largely depends on the applied cutting ceramics (СС). The choice of material for the cutting part of the tool over the centuries has been a priority for science, technology and has been closely associated with the development of metallurgy, and more recently with powder metallurgy, the influence of concentrated energy flows, as well as physics and chemistry of solids.

The technological principles of increasing the physical and mechanical characteristics of oxide and nitride ceramics plates by surface treatment, combining various options of abrasive action and coating are revealed in this article. The author carried out the analysis of wear-resistant coating compositions for various operating conditions of ceramics and provided information about their effect on strength characteristics and the distribution of residual stresses in the surface layer.

New technical solutions for logging, patented by Petrozavsk State University in 2018-2020, are considered. The main directions of patenting these solutions are shown.

The specifics of training of students of forest profile of bachelor 's degree in discipline "Technology and equipment of discontinuous and low-volume cuttings" are considered. There is a list of questions for the front survey of students.

The most important factor in providing people with the required volumes and quality of food in the formation of effective systems of end-to-end technologies for the harvesting of food raw materials and the production of functional foods. The role of transport in these systems is considered.

An increase in the volume of felling of forests and reforestation will improve the breed composition of plantations, its commodity structure in the Republic of Karelia. At the first stage of the intensification, in addition, more than 1 million cu. m of wood, first of all, balance raw materials.

The complex of objects of intellectual property in the field of protection of linear objects and prevention of forest fires is shown by cutting trees and bushes with continuous movement of the machine.

A brief review of the research aimed at improving technologies and equipment for the removal of trees and bushes on felling and line facilities is carried out. Particular attention is paid to the machines for performing these operations with the continuous movement of the machine.

A brief review of the research aimed at improving the technology and equipment for removal of stumps on felling and linear objects is performed. Given perspective technical solutions.

The opinion was expressed and the need to accelerate the development work to solve the problem of cutting trees and bushes with the continuous movement of the forest machine.

In recent years, the system of preparation of logging areas for timber exploitation has been substantially transformed in Russia. The technique of formation of schemes of rational allocation of cutting areas and the order of their development is offered. The technique is worked out on the example of the timber enterprise "Shuyales".

New patents of intellectual property patented by Petrozavodsk University on the construction of equipment for protecting linear objects and preventing forest fires by cutting trees and bushes with continuous movement of the machine are given.

It shows that the development of technology for continuous cutting of trees and shrubs is going towards the creation of multi-functional machines fit into the flexible technology of timber production.

Results of researches of authors group in the field of increase at cutting efficiency by the ceramic cutting tool in the conditions of the automated manufacturing are given in this publication. Main types of cutting ceramics destruction are analyzed. Recommendations about the choice of failure criterion of the ceramic cutting tool in the automated manufacturing are made. The method of calculation of the main characteristics of the ceramic tool reliability, such as failure rate, probability of non-failure, probability of tool failure is developed.

Considered a range of studies carried out in Petrozavodsk university, is provided in the beginning of the study brush cutter, and then devices for continuous cutting of trees and bushes on the linear objects.

An overview of the work aimed at evaluating research in the study of technology removal of trees and bushes in the continuous cutting of them.

Describes an approach to the creation of multi-functional equipment for performing a wide range of works on the cutting area. Its advantage is the use of a single base - crawler tractor.

Considered various technical solutions for continuous cutting wood-brush vegetation in forest industry, construction and maintenance of linear structures

New design of trussed beams of the new cutting. The calculations of all its elements and determined the cost of steel. Built appropriate tables and graphs for various variants of the design.
