摘　　要：本文结合开发国产化软件的实践,详细论述了trimmed体系下CAD/CAM曲面造型系统中几何元素的数据结构及其曲线、曲面的构造方法,导出了trimmed体系下各种参数曲线、曲面的数学描述,进而指出基于trimmed体系的曲线、曲面造型的优越性和灵活性。Aiming at nationalizing computer software, the author discusses the data structures of CAD/CAM geometric factors and ways of construction of curves under trimmed system. The paper also deduces mathematic description of various curve lines and curve surfaces , which shows the advantages and flexibility in the curve-modelling within the trimmed surface system.
