Study on the effect of friction rolling additive manufacturing process parameters on deposition height and molding quality
摘要
The challenging problem of quantitatively regulating friction rolling additive manufacturing (FRAM) process parameters to optimize forming quality and morphology is addressed in this study. A quadratic regression orthogonal combination method is employed to establish the relationship between process parameters, deposition height, and forming quality, thereby constructing a theoretical model of single-pass cross-section deposition. The results indicate that during FRAM multilayer deposition, the deposition height tends to stabilize as the number of layers increases. Among the process parameters, tool head speed has the most significant impact on deposition height. Additionally, the lift-off amount should be smaller than the deposition height to effectively prevent the formation of interlayer defects. This research facilitates stable control of FRAM deposition morphology and layer height and provides valuable guidance for selecting process parameters.
