ActiveSheet metal formability and test methods - Part 6: Conical cup test
金属薄板成形性能与试验方法 第6部分：锥杯试验
Application Summary AI generated
This standard specifies the conical cup test method for evaluating the formability of sheet metal, particularly its stretch-flangeability and resistance to edge cracking. It is applied in the automotive, aerospace, and appliance industries to assess the suitability of metal sheets for deep drawing and stamping processes. The test involves forming a conical cup from a circular blank to measure limiting drawing ratio and failure modes under controlled conditions.
