Bulatasov E.O., Popov V.P., Hanin V.P. MATHEMATICAL MODEL OF WOOD MILLINGThe complexity of the process of cutting wood creates objective difficulties of obtaining a complete and accurate analytical description of the relations between the baseline and performance indicators cutting. To ensure the adequacy of the laws established by theory and experiment, the analysis of the process of cutting the wood necessary to consider many factors, first and foremost — the viscoelastic characteristics of the material being processed. An analysis of the forces from the blade by a timber for cutting the three main directions found that using compressive and tensile stresses occurring in the material being processed in the interaction with a cutter, it is possible not only to describe the process of cutting the wood to cut the three principal directions, and significant differences explain why the cutting force values for these cases, without using such a thing as chopping wood when cutting. It is expected that after cutting the thinnest shavings sharp cutter, the thickness of which is comparable to the radius of the rounding of the blade for wood cutter action to a greater extent can be reduced to the action of the blade, and the action of the front face, since small quantities, can be neglected. The study the mathematical model developed using the mathematical apparatus of rheology, which in theory wood cutting is a new method of mechanics-mathematical analysis, a formula for determining the amount of force cutting wood.Key words: mathematical model, milling wood, rheological model, rheological equation, cutting force.
