The center hole of the automobile disc is typical round hole burring piece with axis-symmetric shape. In this paper, the deformation of such part is analyzed by computer simulation and the distribution regularities of strain, stress change in the round hole burring process investigated. The key parameter affects hole burring——the angle of anode mode is optimized.
