poor, the plex, prone to deformation, in the process of arrangement when it needs to the surface of the main crude Finishing processes to separate and focus on processes. Gradually reduce Jiagongyuliang, cutting force and the role of stress and deformation of the amendment process, will be able to reach parts of the final technical requirements. Design-valve rocker bearing parts of the machining process of order and milling 3mm groove equipment fixture design process, I learned a lot of machining expertise and practical content.Р目录Р1零件的分析?1Р1.1零件的作用?1Р1.2零件的工艺分析?1Р2.1确定毛坯种类?1Р2.2确定毛坯的尺寸公差和机械加工余量:?2Р2.3绘制铸件零件图:?3Р3、拟定零件工艺路线?3Р3.1定位基准的选择:?3Р3.2表面加工方法的确定:?3Р3.3加工阶段的划分:?4Р3.4工序的集中和分散:?4Р3.5工序顺序的安排:?4Р3.5.1、机械加工工序?4Р3.6确定工艺路线:?5Р3.7选择加工设备及刀、夹、量具?5Р4、切削用量、时间定额的计算?6Р5、机床夹具设计?7Р6、学习体会?8Р7、参考文献?10
