1、底板零件的机械加工工艺规程及铣床夹具设计摘要：在生产过程中，使生产对象（原材料，毛坯，零件或总成等）的质和量的状态发生直接变化的过程叫工艺过程，如毛坯制造，机械加工，热处理，装配等都称之为工艺过程。在制定工艺过程中，要确定各工序的安装工位和该工序需要的工步，加工该工序的机车及机床的进给量，切削深度，主轴转速和切削速度，该工序的夹具，刀具及量具，还有走刀次数和走刀长度，最后计算该工序的基本时间，辅助时间和工作地服务时间。机械工业是一种基本工业形式，对于我们国家来说，它关系到国计民生的方方面面。近年来机械工业领域向着高精度、高质量、高效率、低成本方向发展，数字化，自动化水平日
2、益提高。同时由于机械工业的发展，其他各工业部门也向着高深度迈进，机械工业的发展日趋重要。机械制造过程及检测，检验中，都要使用大量的夹具夹具是能够使产品按一定的技术要求准确定位和牢固夹紧的工艺装置，它的主要用于保证产品的加工质量、减轻劳动强度、辅助产品检测、展示、运输等。因此，如何设计好机床夹具则成了机械制造的一项重要任务。机床夹具是夹具中的一种，将其固定到机床上，可以使被加工件对刀具与机床保持正确的相对位置，并克服切削力的影响，使加工顺利进行。机床夹具分为通用夹具和专用夹具两种。 此次论文，主要是对普通卧式铣床上槽类零件的专用夹具进行研究、分析。 关键词：工序；工艺；定位
