Three dimensional free bending flexible forming technology is an important technological innovation in the international plastic forming field in recent years. This technology mainly controls the position and posture of the forming system in the three-dimensional space to achieve orderly and directional flow of materials to obtain three-dimensional complex components. The technology belongs to dieless forming, with fast forming speed, high forming precision and wide material adaptability. Germany, Japan and the United States have industrialized the free bending forming technology and equipment, and successfully applied this technology to their respective countries' aerospace, weapons and equipment, as well as various types of civil products, resulting in significant economic and military benefits. At present, the core and key technologies of foreign equipment have blocked our country
