摘　　要：针对单点渐进成形几何精度差的问题,提出了一种双点渐进成形加工技术。以1060铝为研究对象,确定目标零件,从成形轨迹和进给量两个方面编制双点渐进成形工艺和单点渐进成形工艺。然后根据编制的工艺在渐进成形设备上编制数控程序,制作了单点与双点渐进成形样品。再使用FARO便携式三坐标测量仪,测量了双点渐进成形与单点渐进成形样品的几何精度。最后,提出了一种对比分析数据的方法,对单点渐进成形和双点渐进成形的几何精度进行了定量的对比分析。实验结果表明,在工艺参数相同的前提下,双点渐进成形的几何精度远高于单点渐进成形的几何精度。Aiming at the poor geometric accuracy of single point incremental forming for aluminum alloy sheet, two points incremental forming technology was presented. With aluminum 1060 as the research object, samples of single point incremental forming and two point incremental forming were made in the same process parameters. Then, the geometric accuracy was measured by FARO three coordinates measuring instrument. Finally, a method was proposed to analyze the data and the analysis of the contrast experiment was done quantificationally. The results indicate that, with the same process parameters, the geometric accuracy of two points incremental forming is obviously hi^her than single ooint incremental forming_
