Abstract：The optimization process of aviation sheet metal is introduced. Through CAD/CAM and laser cutting technology, the stamping bends are exactly unfolded for near end shape and to increase the utilization rate of the materials. To cancel the allowance process and decrease the manufacturing cost, the near end shape bend forming technology is investigated with stamping instead of brazing. And the percent of pass for once brazing is increased through the technical increase of stamping and brazing process.
