中文摘要：

在复杂形状板材件的数控渐进成形中，各个形体的挤压顺序影响着成形质量。为了分析挤压顺序对成形质量的影响，在给出三种挤压顺序的基础上，研究了三种挤压顺序的数控渐进成形的三种成形轨迹生成方法，并以三种挤压顺序分别制作出板材件且分析了其成形质量。研究结果对挤压顺序的确定具有指导意义。

英文摘要：

The extrusion sequence of each characteristic affects the forming quality in the NC incremental forming of complicated shape sheet part. In order to analyze the impact of extrusion sequence on forming quality,on the basis of the three kinds of extrusion sequence,the generation method of the three kinds of forming paths in the three kinds of extrusion sequence of NC incremental forming was studied. The sheet parts were formed respectively by using the three kinds of extrusion sequence, and the forming qualities were analyzed. The research results have guiding significance for the determination of the extrusion sequence.
