Description
Summary:To achieve high machining efficiency in optimal surface integrity manufacturing, a relationship model between rolling depth and rolling force was established based on Hertz contact theory, and a theoretical model of impact characteristics was established according to the indentation geometry to evaluate the machining efficiency. Subsequently, the plane ultrasonic rolling experiment of 7075 aluminum alloy was carried out to verify the relationship between rolling depth and rolling force; meanwhile, the mapping between process parameters and surface characteristics, impact characteristics, and surface morphology were studied, respectively. On this basis, the surface integrity prediction model was established by using nonlinear curve fitting method, and the optimal parameter solution was obtained by using quantum genetic algorithm (NSGA-II). The results show that the rolling force increases linearly with the increase in rolling depth. The impact characteristics increase with the increase in static force and amplitude, and decreases with the increase in step and feed speed, and the impact characteristics is negatively correlated with the processing efficiency. The optimization results provide a reference for engineering applications.
