旋压是用于成形薄壁空心回转体零件的一种金属压力加工方法。作为一种特殊的塑性加工工艺,旋压加工属于无切削连续局部回转成形范畴[1~3]。具有加工变形抗力小、节约材料、产品质量好等优点,被广泛用于航空航天、武器装备、工程机械制造等领域[4]。用软件模拟旋压过程可节省时间和实际开销,模拟出的 Spinning is a metal pressure machining method used to form thin-walled hollow rotating parts. As a special plastic processing technology, the spinning process belongs to the category of non-cutting continuous local rotary forming [1 ~ 3]. Has the advantages of small processing deformation resistance, material saving, good product quality, etc., is widely used in aerospace, weapons and equipment, construction machinery manufacturing and other fields [4]. Simulation of the spinning process with software saves time and money and simulates it
