Abstract

The development of mechanical engineering in the woodworking industry places new and high demands on the creative potential of specialists. In addition to professional training, scientists and research engineers are increasingly faced with the necessary tasks, such as knowledge of methods for processing observation results, experiment planning, mathematical modeling and optimization methods. In addition, it is important to note that experimental research methods in woodworking play an important role.

To date, several studies have been conducted on the development of new models of milling cutters for processing wood and lumber. However, with the creation of new machines with digital control and the improvement of the design of milling tools, new research is needed related to the optimal and economical use of material and energy resources and the improvement of the technological mode of operation of equipment. Thus, it is possible to save foreign currency assets of enterprises, thereby replacing imports and increasing the competitiveness of manufactured products.

In the presented work, the results of experimental studies of a new design of a milling tool were obtained, which determined the effect of the axial rotation of the knife on power indicators when milling pine wood as the most common species in furniture woodworking enterprises. Research allowed to establish the maximum value of the axial angle, equal to 34°, at which the power consumption decreased by 41%.
