The creation of laboratory equipment that provides a clear demonstration of the studied technological processes while ensuring the possibility of its use for research purposes by students is an urgent task. Purpose of the work: development of a stand design for a visual demonstration to students of the process of the impact of the cutting working body on the workpiece while ensuring the possibility of fixing the characteristics of the cutting process. In the course of the work, on the basis of system analysis, the classification of laboratory equipment for studying the cutting process was carried out, its features were studied, highlighting the advantages and disadvantages, and an original design of the stand was proposed. The design of the stand provides an opportunity to study the characteristics of the cutting process with a fixed fixation of the workpiece and the movement of the cutting tool, which clearly simulates the real cutting process and allows you to determine its parameters.

An analysis of the use of modern technologies based on the use of physical phenomena, namely, vacuum and microwave effects in the dehydration of food products, is given. On the basis of generalization and analysis of studies of domestic and foreign scientists it was shown that these technologies are promising for such plant raw materials as fruits and vegetables, and their effectiveness depends on the characteristics of the raw materials being enriched

The article presents a method for searching for new technical solutions. The method is based on a functional-technological analysis of a system, including pointing out its separate elements and studying the interaction between them. The efficiency of the presented method is shown on an example of improvement of an increment borer construction. Application of a functional-technological analysis allows bringing technics development to a new level.

The article describes the construction of a modern forest instrument for forest inventory operations. The equipment consists of a caliper and a built-in marking device. The developed construction allows conducting two operations simultaneously: determination of a trunk diameter and marking a measured tree trunk. The suggested construction leaves visual marks on measured tree trunks automatically, that allows avoiding doubling of measuring results.

The article examines the existing methods for coupe demarcation and the ways of fixation of wood plots at an area for future logging works. A new method is suggested, based on using RFID-technologies. Fixation of borders in this method is realized using RFID-tags with recorded information placed into the ground. Using the suggested method will allow lowering the labour intensity of coupe demarcation, fixing of exact borders of a logging site at an area, eliminating logging works out of the bounds of cutting areas, etc.
