    Abstract: Structured surface, known for its excellent drag reduction and lubrication properties, has become an important means of enhancing the functional performance of mechanical equipment surfaces. In order to fabricate a structured surface on the cylindrical workpiece, this paper proposes the method of creating surface structures through the sinusoidal motion rolling of steel balls. To implement this method, a sinusoidal rolling motion model was established. Computer simulations were used to analyze the influence of rolling motion parameters on the formation of the structured surface morphology. The research results indicate that the designed steel ball sinusoidal motion rolling method can effectively achieve the manufacturing of structured surfaces on cylindrical exteriors. During the axial feed rolling process, by adjusting the vibration frequency, amplitude and axial feed speed, the characteristics of the structured surface can be altered. By selecting the appropriate vibration frequency, amplitude, and axial feed rate, a uniform mesh structure can be obtained.
