在对管切割中影响尺寸精度和相贯线形状的误差源进行分析的基础上，提出了一种示教再现的误差补偿切割方案，并建立了相应的误差分离模型。
Based on the analysis of the error sources that affect the dimensional accuracy and the shape of the intersecting lines in the pipe cutting, an error compensation cutting scheme for teaching reproduction is proposed and a corresponding error separation model is established.
