In the process of design should first understand the analysis of parts, parts of the process to design a blank structure, and choose the ponents 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 ponents of the design, such as connecting parts positioning device, clamping element, guiding element, clamp and machine tools and ponents; positioning error is calculated when the fixture, analysis the rationality and ing of fixture structure, improve and design in later. Keywords: process, process, cutting, clamping, positioning, error 沈阳工学院毕业论文 IV 目录摘要····································································································· II Abstract ··································································································· III 第 1章绪论··································································
