In the process of design should first of all parts to analyze, understand parts of the process and then design a blank structure, and choose the good parts of the machining datum, designs the process routes of the parts; then the parts each step process dimension calculation, the key is to determine the process equipment and cutting the amount of each working procedure design; then a special fixture, fixture for the various components of a design, such as the connecting part positioning device, clamping element, a guide element, clamp and the machine tool and other components; the positioning error caused calculate fixture when positioning, analysis of the rationality and deficiency of fixture structure, pay attention to improving and will design in.Keywords: process, process, cutting, clamping, positioning,目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc418710404 摘 要 PAGEREF _Toc418710404 \h II HYPERLINK \l _Toc418710405 Abstract PAGEREF _Toc418710405 \h III HYPERLINK \l _Toc418710406 第1章 序 言 PAGEREF _Toc418710406 \h 1 HYPERLINK \l _Toc418710407 第2章 零件的分析 PAGEREF _Toc418710407 \h 2 HYPERLINK \l _Toc418710408 2.1零件的形状 PAGEREF _Toc418710408 \h 2 HYPERLINK \l _Toc418710409 2.2零件的工艺分析 PAGEREF _Toc418710409 \h 2 HYPERLINK \l _Toc418710410 第3章 工艺规程设计 PAGEREF _Toc418710410 \h 4 HYPERLINK \l _Toc418710411 3.1 确定毛坯的制造形式 PAGEREF _Toc418710411 \h 4 HYPERLI
