3、序进行尺寸计算，关键是决定出各个工序的工艺装备及切削用量；然后进行专用夹具的设计，选择设计出夹具的各个组成部件，如定位元件、夹紧元件、引导元件、夹具体与机床的连接部件以及其它部件；计算出夹具定位时产生的定位误差，分析夹具结构的合理性与不足之处，并在以后设计中注意改进。关键词：工艺、工序、切削用量、夹紧、定位、误差。全套图纸，加-23-AbstractAbstractThisdesigncontenthasinvolvedthemachinemanufacturecraftandtheenginebedjigdesign,themetal-cuttingmachinetool,thecom
