翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Blanking and piercing ： ウィキペディア英語版 Blanking and piercing Blanking and piercing are shearing processes in which a punch and die are used to modify webs. The tooling and processes are the same between the two, only the terminology is different: in blanking the punched out piece is used and called a ''blank''; in piercing the punched out piece is scrap.〔Degarmo, p. 427.〕 The process for parts manufactured simultaneously with both techniques is often termed "pierce and blank." An alternative name of piercing is punching. ==Characterization of part quality and potential defects== Burrs and die rolls are typical defects of trimmed surfaces. The surface finish will be lower in the so-called fracture zone, i.e. where the material is irregularly stripped away from the matching surface, at the end of the shearing operation. Die roll is a plastic deformation of the sheet edge, which causes permanent edge rounding. Burr height is typically used as an index to measure tool wear, because it is easy to measure during production. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Blanking and piercing」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
