Stamping is a widely used method for manufacturing parts from metal, plastic, and other materials. This method allows obtaining parts with high precision of dimensions and shape, as well as with good mechanical properties. However, stamping is often accompanied by surface defects and insufficient product accuracy. These defects can lead to a decrease in the quality of parts and their operational characteristics. One of the ways to improve the surface quality of parts in stamping is the use of vibrations. Vibrations can affect various factors that influence the surface quality of parts, such as friction force, material distribution, and deformation. The article examines the influence of broadband micro-amplitude vibrations on the surface quality of parts in stamping. The authors of the article developed three mathematical models that describe the behavior of friction force, material distribution, and deformation under vibration conditions. The research results showed that vibrations can improve the surface quality of parts in stamping, especially for soft materials. Vibrations can reduce the friction force between the tool and the workpiece, which can lead to a reduction in burrs and other surface defects. Vibrations can also improve the material distribution in the stamping zone, which can help increase product accuracy, enhance surface quality, and improve the productivity of the technological process. The authors of the article assert that the mathematical models developed within their research are useful tools for predicting the impact of vibrations on the surface quality of parts. These models can be used to optimize stamping parameters to achieve the best surface quality of parts.
