In the process design, the parts are analyzed first, the process of the parts is redesigned and the structure of the blank is redesigned. The process datum of the parts is selected and the process route of the part is designed. Then the size calculation of the working procedure of the parts is calculated, the key is to determine the process equipment and the cutting amount of the various working order; then, the key is to determine the amount of the process equipment and the cutting amount. The design of the special fixture is carried out, and the components of the fixture are designed, such as the positioning element, the clamping element, the guiding element, the connecting parts with the machine tool and the other parts. The positioning error is calculated when the fixture is positioned, and the rationality and inadequacies of the fixture structure are analyzed, and the design is injected in the future. It is intended to be improved.Key words: cutting amount clamping positioning error.目 录 摘要II第1章 序 言1第2章 计算生产纲领、生产效率分析22.1生产纲领22.2 生产效率分析22.3 生产类型2第3章 零件的分析43.1 零件的作用43.2 零件的工艺分析4第4章 工艺规程设计54.1 确定毛坯的制造形式54.2 基面的选择54.3 制订工艺路线64.4 确定各工序的加工余量74.5 基本工时的确立8第5章 车床夹具设计345.1 专用夹具的提出345.2 定位装置设计345.3定位元件的选择345.4定位误差分析345.5 切削力的计算与夹紧力分析355.6 夹具设计及操
