The article proposes a design for a specialized testing machine intended for the local evaluation of strength characteristics of metallic and composite materials using the controlled drilling method. The working principles of the setup are examined, including the systems for recording axial force, torque, and temperature fields in the cutting zone. Special attention is given to data processing techniques that enable the determination of specific fracture energy, shear strength, and dissipative properties based on the analysis of kinematic and force parameters of the drilling process. A mathematical model of drilling has been developed, and the results of a numerical simulation in SimInTech software are presented, confirming the feasibility of the concept. The advantages of the proposed method over traditional destructive testing techniques are discussed, including the ability to minimize material damage zones and automate measurements. The developed concept can be used to create both stationary laboratory setups and portable devices for real-time monitoring of structural materials in industrial environments.
