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.

The use of mulcher machines is a promisingmethod of preventing and combating forest fires. Whenpreparing forest areas with the use of mulcher machines the soil is crushed altogether with the vegetation growing on the surface, roots and otherwood inclusions, while the process of interaction of the working body with the soil requires significant energy costs. The analysis of the mulcher operating modes with a working body in the form of a drum-chopper has been carried out and, as the result, the operating modes of the mulcher machine have been determined. The mulcher machine operation mode when cutting woody vegetation has been examined. A computer program has been developed to determine the rational parameters and operating modes of the mulcher machine.
