UD cloth, namely unidirectional fiber cloth, is a composite matrix composed of unidirectional fibers arranged in parallel, which can provide the characteristics of high strength and low elongation. With the continuous improvement of the requirements for the dimensional accuracy and efficiency of composite parts, the precise cutting technology of UD cloth has become a research hotspot. The traditional manual cutting method is not only inefficient but also difficult to ensure the cutting accuracy, resulting in material waste and increased production costs.
