In the process of design should first carries on the analysis to the components and parts of the process to understand the design of blank structure, and choose the good components the processing datum, designs the process routes of the parts; then the parts of each step of process dimension calculation, is the key to decide the craft equipment and the cutting dosage of each working procedure; design then the special jig, fixture for the various components of the design, such as the connecting part positioning device, clamping device, guide device, clamp and the machine tool and other components; the positioning error calculate fixture positioning, analysis of the rationality and deficiency of fixture structure, pay close attention to the improvement and design in later.Keywords: process, process, cutting, clamping, positioning error目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc466901830 摘 要 PAGEREF _Toc466901830 \h II HYPERLINK \l _Toc466901831 Abstract PAGEREF _Toc466901831 \h III HYPERLINK \l _Toc466901832 目 录 PAGEREF _Toc466901832 \h IV HYPERLINK \l _Toc466901833 第1章 序 言 PAGEREF _Toc466901833 \h 1 HYPERLINK \l _Toc466901834 第2章 零件的分析 PAGEREF _Toc466901834 \h 1 HYPERLINK \l _Toc466901835 2.1零件的形状 PAGEREF _Toc466901835 \h 1 HYPERLINK \l _Toc466901836 2.2零件的工艺分析 PAGEREF _Toc466901836 \h 2 HYPERLINK \l _Toc466901837 第3章 工艺规程设计 PAGEREF _Toc466901837 \h 3 HYPERLINK \l _Toc466901838 3.1 确定毛坯的制造形式 PAGEREF _Toc466901838 \h 3 HYPERLI
