vibrations can be attributed to inertial forces generated by the crank-slider mechanism, since the slide undergoes acceleration and deceleration during each cycle, the bearings are subjected to fluctuating dynamic loads. These inertial loads manifest as vibration bursts synchronized with the reversal points of slide motion. Under loaded conditions (Figure 7b), the same phenomenon is present; however, in the radial directions of the shaft, an additional response arises from the impact between slide and block. From the obtained results, it can be concluded that slide acceleration signals enable monitoring of the stamping process and its phases. These signals reflect the dynamic response of multiple press components to the excitations generated during stamping. Combined with frequency-domain analysis, accelerations can be used to assess the struc tural integrity of components. Furthermore, the di ff erent loading conditions have a strong influence on the measured vibrations, allowing detection of di ff erent operating conditions and changes in applied load. The vibrations observed throughout the press arise from the motion of shafts, connecting rods, and the slide, as well as impacts, inertial e ff ects,
