Abstract The technological process analysis method for cylindrical part production in machine building industry adopts the annular material to be deformed plastically into cylindrical wall as research object, adopts the width b, thickness t, drawing deformation characteristic factor b/d and 1g b/t as main expression factors, and combines the parameters of cylindrical part, die, material performance, etc. into a mathematical expression to simulate the relationship among the various factors. The present invention makes it possible to determine via calculation once forming limit, depth-drawing force, edge-pressing force, blank correction, notch formation, hem in inner hole, etc., accurately and practically.
