Modeling the technological process of cutting northern reindeer antlers

The objective of the study is to simulate the technological process of cutting reindeer antlers for the development of new technological equipment. Tasks: study of physical parameters of reindeer antlers; mathematical description of the antler cutting process; determination of the main parameters of the technological equipment for cutting reindeer antlers. The object of the study is reindeer antlers harvested in the Surindinsky Experimental Farm of the Evenk Municipal District. The subject of the study is the technological parameters of the equipment for cutting reindeer antlers. The physical parameters of reindeer antlers were studied by measuring the main parameters of 31 freshly cut antlers and their subsequent processing using statistical methods. It was found that the mathematical equation of the relationship between the antler mass and the cut diameter, the mass and length of the antlers has a linear dependence, the tightness of the relationship by the correlation coefficient is r1 = 0.8, r2 = 0.79, which shows a high tightness of the relationship between the variable parameters. Mathematical modeling of the technological process of cutting antlers was carried out using the theory of deformation and cutting, and the coefficient of elasticity primarily depends on the diameter along the cutting line, as well as the period of cutting the antlers. To solve the problem of squeezing in order to reduce the blood loss of the animal, longitudinal deformation is not needed, to ensure a gentle technology for cutting antlers, it is necessary to ensure the continuity of the cutting process, and the sharpening angle of the cutting surface is important to ensure the squeezing process. The results of the conducted research showed that the main technological parameters for designing new technological equipment are the average size of the antler cut diameter (D = 45 mm), the compression force of the cutting mechanism (F = 2500 N), the sharpening angle of the cutting mechanism blade (δ = 60°) to ensure the process of squeezing the outer surface of the antler diameter with the possibility of squeezing blood vessels.
