3、刀具与夹具 切削加工及刀具是装备制造业的基础工艺，是制造业重要工业部门如汽车工业、家电制造业、航空航天、能源工业、模具工业等发展的关键技术。 现代切削技术经过近百年的快速发展，到 20 世纪末，随着数控机床、数控系统、刀具材料、涂层技术等制造技术的全面进步，达到了新的水平，使切削加工进入了高速切削的新阶段，其主要技术特征表现为切削速度有 5 10 倍的提高。高速切削技术的出现，对制造领域又提出了高要求。一是机床本身刚性、精度高，二是装夹系统刚性、精度高。三是刀具的材料性能和加工精度要高。四是冷却效果要好。 。

4、专用钻床 夹具 是针对特定零件孔加工时使用的夹具。此类钻床夹具能较易保证孔之间的位置精度，提高生产效率。应用此钻模能 极大地提高劳动生产率、降低操作工人的劳动强度 ,减小钻头的损耗 ,长刀具的使用寿命 。 在夹具设计工作中，一般具有下列特点： 1、夹具的设计周期较短，一般不进行强度和刚度计算； 2、专用夹具的设计，对产品零件有较强的针对性； 3、确保产品加工质量，提高劳动生产率是夹具设计工作的首要任务； 4、夹紧装置的设计对整个夹具的结构具有决定性的影响。夹具设计的原则是经济和实用，夹具设计的基本要求有以下三方。
