1、本科生毕业设计（论文）摘要本论文的题目是底座零件工艺工装设计及CAD/CAM，题目来源于锦州双菱精密铸造有限公司。根据该公司的生产能力和设备情况，设计完成了零件的熔模模具、零件的工艺规程及典型专用夹具。在此基础上，基于CAD/CAM技术，完成了夹具的机构仿真。论文在介绍了熔模铸造、机械加工工艺规程制定总过程、模具CAD/CAM及其优势的基础上，详细的叙述了熔模模具设计、工艺规程设计及机床夹具设计内容及方法。其中模具设计主要有零件毛坯的三维造型设计，模具的分型面设计，模具的开模干涉分析，浇注系统、定位及锁紧机构的设计；工艺规程设计包括加工方法的选择，定位和夹紧方式的选择，机
2、床和刀具的选择，切削用量的计算和工艺路线的制定；而夹具设计则解决了定位误差和夹紧力等问题的分析。最后，论文介绍了工件装夹机构的仿真。包括机床和刀具选择，切削参数的设定，加工过程的仿真和主轴运动速度的分析等内容。综上，本论文以零件工艺工装设计理论为依据，进行了底座零件的熔模模具和工艺工装设计及CAD/CAM技术的实际应用。关键词：三维实体模型；熔模模具；工艺；夹具；机构仿真VI本科生毕业设计（论文）AbstractThetopicofthisgraduationdesignisthedesignofprocessingplanning，toolingdevicesandCA
