摘　　要：板料零件数控渐进成形工艺是一种通过数字控制设备,采用预先编制好的控制程序逐点成形板料零件的柔性加工工艺。文章利用数控实验机床(CNC)对热浸渡钢板H180YD+Z的渐进成形性能进行研究,测试了成形极限角和成形性能曲线。结果表明,该材料在渐进成形过程中,其零件厚度分布基本符合t=t0cosθ的规律,成形性能好,可适用于汽车钣金件的渐进成形,为板材的渐进成形工艺提供了理论依据。NC incremental sheet metal forming is a flexible process which forms the parts point by point with NC forming machine according to the prepared program .The experimental tests about the formability ,namely the maximum forming limit angle and the forming limit diagram ,was done for hot galvanized automotive steel sheets H180YD＋Z .The experimental results show that , in the incremental sheet metal forming process , the thickness distribution obeys the cosine law t= t0cosθ. The material H180YD＋Z ,which can be used in incremental forming for automotive sheet parts ,has good formability .This paper provides a theoretical basis on sheet incremental forming .
