Choose the correct processing methods, design the reasonable process. In addition to the stuffing box cover part two process designing special fixture.Machine tool fixture of many kinds, among them, the most widely used common fixture, size specifications have been standardized, and a professional production plant. While widely used in batch production, specially for a workpiece processing services for the fixture, it needs each factory according to workpiece machining technology to design and manufacture. In this paper, fixture design are the main contents of design of fixture for grinding center.Key words: scaffold, processing technology, processing method, process documentation, fixture PAGE 5目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc344995884 摘 要 PAGEREF _Toc344995884 \h 2 HYPERLINK \l _Toc344995885 Abstract PAGEREF _Toc344995885 \h 3 HYPERLINK \l _Toc344995886 目 录 PAGEREF _Toc344995886 \h 4 HYPERLINK \l _Toc344995887 1 绪 论 PAGEREF _Toc344995887 \h 6 HYPERLINK \l _Toc344995888 2 零件的分析 PAGEREF _Toc344995888 \h 5 HYPERLINK \l _Toc344995889 2.1零件的工艺分析 PAGEREF _Toc344995889 \h 5 HYPERLINK \l _Toc344995890 2.2 零件的工艺要求 PAGEREF _Toc344995890 \h 5 HYPERLINK \l _Toc344995891 3 工艺规程设计 PA
