Process Analysis of Precision Press Forming by the Finite Element Method

유한요소법을 활용한 정밀전자부품 성형공정 해석

The multistage precision forming process for aperture of electronic guns consists mainly of drawing and swaging operations. The multistage forming sequence is analyzed in view of production industry, and based on the industrial investigation. The processes are simulated by the finite element code MARC. The elastic recovery, strain and stress distribution, and the die forces are summarized.
