Abstract
Recent industrial requirements for highly precise shape processing have brought the electric discharge machining (EDM) in great need. High precision in EDM is primarily achieved by high performance controllers. However there exists inherent precision loss due to structural deformation. On this background, we study structural deformation characteristics of wire cut EDM via finite element (FE) analysis and axiomatic design. Two different wire cut EDMs are selected as analysis models. 3D CAD package I-Deas is first used to construct FE models of wire cut EDMs, and then ABAQUS FE code is used for following structural analysis. Pertinency of FE mesh refinement is discussed in terms of
본 연구에서는 유한요소해석을 통한 와이어 방전가공기의 설계검증을 위하여 두 모델을 선정하여 CAD 패키지 I-DEAS를 이용하여 3차원 유한 요소모델을 모델링한 후 상용 유한요소해석코드인 ABAQUS로 각 모델의 가공위치에 따른 해석을 수행하였다. JW-35A와 JW-60A 두 모델의 상호 비교 타당성 여부를 확인하기 위하여
