Scientific and Experimental Substantiation of the Key Geometric and Kinematic Parameters of Vibrocutting Machines

Abstract The process of cutting with a blade is largely applied in technological equipment used in the agricultural production complex and is used to process raw materials with different physical and mechanical properties. Nonetheless, the relation between the parameters of processing with vibroblade and the rheological properties of the processed material is insufficiently studied, while it is an important issue of practical significance.As a result of laboratory experiments, it became possible to obtain the power characteristics of vibrocutting of common reed, establish an optimal combination of factors: vibration amplitude, frequency and the speed of the blade delivery to ensure the minimum vibro-cutting force. As a desirable kinematic regime, 𝐾 =𝑉/𝑉𝜏 , the following relation of speed of delivery and vibration speed of the toothed blade: ≅ 0.004.
