Analysis of a Process Sequence in Precision Press Forming of Aperture and Construction of Design System

정밀 전자총 부품 Aperture 성형공정 해석 및 설계 시스템 구축

A process sequence in precision press forming of electrnic components is investigated by the finite element method. Aperture, a key component of electronic gun, is formed through a sequence of about 15 operation, among which the beading & bending, the first piercing, the first coining, and the second coining operations are expected to be most critical in view of industrial experts opinions. Thus, the analysis per- formed by a commercial code MARC focuses on the three operations, and comparisons are made between the results of the analysis and the measurements of experimental forming of the component.
