Purpose. To create a mechatron model of vacuum tube vibration system for rock cutting by flat auger tools based on physical and mechanical properties of processed array and kinematic characteristics of the instrument. Methodology. The analytical model of the fracture process of rock cutting by tool vibration considering plastic properties of the massif was developed. The main technological parameters of massif vibrating cutting with normal variations were modelled: dependences of normal and tangential pressure in the zone of working body interaction with the medium, normal and shear stresses in the zone of destruction, rock characteristics of the medium, vibration parameter dependences on the characteristics of mechatronic system geometry of the contact area of flat chisel treated with medium. Findings. The choice of the computational model of the vibration rock cutting with the normal to the direction of movement of the working body fluctuations was substantiated considering the processes arising from destruction: the occurrence of compressive and tensile stresses. The main stages and interconnection options in the simulation of vibration cutting were established. Originality. Scientific novelty lies in the development of a method of analysis of contact interaction of roller working body molding machine with an array taking into account the changes in the stabilization process of physical and mechanical properties of the treated medium, the aim of which is to predict the required voltage and depth of the formed layer. Practical value. The theoretical basis of rock cutting by flat auger tool taking into account the normal component of the vibration with regard to the movement direction allowing for the deformation of the rock mass and the contact interaction with the working body was established, that allows improving the technology of drilling wells by reducing the power consumption of the cutting process. The results enable us to determine the parameters of power and kinematic conditions for the occurrence of the vibration cutting.
