Abstract: The complex for the removal and analysis of experimental data contains a unit for obtaining the coefficients of rigidity of the cutting tool elements and a unit for removing the values of vibration accelerations and recording the values of roughness (the unit is mounted on the basis of the EqiptopETM-510 machine with the Fanuc 01-MB CNC system). Using the above-mentioned units, it was possible to obtain arrays of values necessary for the dynamic analysis of the cutting tool and their further mathematical processing that determine its dynamic behavior include the reduced mass, reduced stiffness coefficients, and damping coefficients. These coefficients were determined through direct and indirect measurements, as described below. The complex for the removal and analysis of experimental data contains a unit for obtaining the coefficients of rigidity of the cutting tool elements and a unit for removing the values of vibration accelerations and recording the values of roughness (the unit is mounted on the basis of the EqiptopETM-510 machine with the Fanuc 01-MB CNC system). Using the above-mentioned units, it was possible to obtain arrays of values necessary for the dynamic analysis of the cutting tool and their further mathematical processing. To determine the cutting forces and establish their further connection with the processing modes, the complex included a three-axis dynamometer, the UDM-600. The assessment of the stability of the cutting tool's operation was carried out using the well-known algebraic Rauss-Gurwitz criterion [6], which is still relevant. The assessment of the stability of the cutting tool during the preparation stages of mechanical engineering production allows for the selection of advanced tool designs for further processing, thereby increasing their durability (reducing the time required for tool changes) and improving the accuracy and quality of the final product.
