The specification by studying the flange parts machining accuracy and its structure characteristics, to guarantee the machining accuracy of the part, using existing now manufacturing technology, based on the positioning for machine design and manufacturing of our learning based on the principles and clamping principle, formulated a set of reasonable fixture model, fast processing the existing manual for analysis and parison of all kinds of positioning and clamping device, the calculation of clamping force and location error checking, guarantee the machining accuracy of the the same time, analysis and calculation of clamping force, ensure the parts in clamping state whether meet the clamping of the workpiece does not generate deformation.Keywords: fixture design, flange, positioning, clamping目 錄第1部分：法蘭盤加工工藝規(guī)程1 工件的簡要分析 1 工件的用途 1 工件的工藝性分析 12 確定毛坯 2 毛坯材料 2 確定毛坯技術(shù)要求 2 鑄件機(jī)械加工余量確定與毛坯圖 23 基面的選擇 6 粗基準(zhǔn)的選擇 6
