In the process of design should first understand the analysis of parts, parts of the process to design a blank structure, and choose the good components the processing datum, designs the process routes of the parts; then the parts of each labor step process size calculation, is the key to decide the craft equipment and the cutting process of the various design parameters; then the special fixture, the fixture selection for the various components of the design, such as connecting parts positioning device, clamping element, guiding element, clamp and machine tools and other components; positioning error is calculated when the fixture, analysis the rationality and shortcoming of fixture structure, improve and design in later. Keywords: process, process, cutting, clamping, positioning, error 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc419023074 摘 要 PAGEREF _Toc419023074 \h II HYPERLINK \l _Toc419023075 Abstract PAGEREF _Toc419023075 \h III HYPERLINK \l _Toc419023076 第1章 序 言 PAGEREF _Toc419023076 \h 1 HYPERLINK \l _Toc419023077 第2章 零件的分析 PAGEREF _Toc419023077 \h 2 HYPERLINK \l _Toc419023078 2.1零件的形状 PAGEREF _Toc419023078 \h 2 HYPERLINK \l _Toc419023079 2.2零件的工艺分析 PAGEREF _Toc419023079 \h 3 HYPERLINK \l _Toc419023080 第3章 工艺规程设计 PAGEREF _Toc419023
