The automotive industry is undergoing continual transformation in response to evolving market demands. In pursuit of enhanced operational efficiency and extended service life of cutting tools, a novel device for the measurement of cutting forces has been developed. Central to this system is a three-axis piezoelectric force sensor, which facilitates improved monitoring of the cutting process and contributes to increased durability of the cutting tool. The development process encompassed all stages—from conceptual design to the realisation of a fully functional prototype—while adhering to the dimensional constraints imposed by machine tool installations. The design and functionality of the individual components comprising the measuring device are systematically presented. Upon completion of the design phase, a numerical model of the device was constructed using the finite element method (FEM). This enabled an analysis of the sensitivity drop experienced by the force sensor due to its integration within the mechanical structure of the device. Furthermore, the measurement equipment and experimental methodologies employed are described in detail. The device was subjected to experimental testing to validate its performance and to assess its practical applicability in force measurement during cutting operations.
