Abstract：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 higher than single point incremental forming.
