INFLUENCE OF THE PARAMETERS OF THE SAW TEETH ON THE QUALITY OF SPRAYING OF HARD-BROAD WOOD

Abstract

The article covers issues related to the influence of saw tooth parameters on the quality of sawing hardwood. It is shown that in Ukraine, hard hardwoods make up about 30%, and the most common of them are oak, beech and ash. These types of wood differ significantly in their physical and mechanical characteristics from the wood of soft deciduous and coniferous species. Such basic indicators of the physical and mechanical properties of hardwood wood as density, strength limit during compression along the fibers, static hardness are approximately several times higher than, for example, in pine. Such increased values of the physical and mechanical indicators of hard hardwood wood lead to an increase in the specific work of cutting, as well as a more intense dulling of saw teeth, which negatively affects the quality of sawing.
