With the rapid development of spinning technology, the spinning forming of LED radiator parts has important significance for the development of parts manufacturing technology. This paper is based on the characteristic analysis of deformation zone and the mathematical analysis of stress field in LED radiator parts forming, with the principal stress method in the theory of metal plastic forming and consider the influence of material thickness change and work hardening to establish mathematical model of stress field and calculation formula of spinning force, and use SIMUFACT simulation and MATLAB calculation to further analysis.
