Southwest university of science and technology本科毕业论文叉形叶根刀R刀片加工效率提升问题研究学院名称制造学院专业名称机械设计制造及其自动化学生姓名学号指导教师二〇一三年六月叉形叶根刀R刀片加工效率提升问题研究摘要：可转位刀具是使用可转位刀片的机夹刀具。也即是将预先加工成形并带有多个切削刃的多边形刀片，用机械夹固的方法夹紧在刀体上的一种刀具。当在使用过程中一个切削刃磨损后，只要将刀片的夹紧元件松开，转位或更换刀片，使新切削刃进入工作位置，再经夹紧就可以继续使用。[1]可转位刀片是可转位刀具的切削部分。虽然可转位刀具的结构简繁多样，但是可转位刀片却是其至关重要的零件，刀刃磨钝后，只需转位或更换可转位刀片便可继续进行切削。本文研究的R刀片是针对汽轮机大叶片叉形叶根结构加工的机夹铣刀专用刀片。在原始加工工艺工时较长，生产效率低，不利于批量生产的情况下，经过对车间生产实际情况进行综合分析，通过原始加工工艺的改善和机床专用夹具的设计，运用机械制造技术及相关课程知识，解决R刀片在加工中的定位、夹紧以及工艺路线的安排等方面的相关问题，在保证零件的加工质量基础上，提高其生产加工效率。关键词：可转位刀具；可转位刀片； R刀片；加工工艺；专用夹具；加工效率Power roller line design and researchAbstract：Indexable cutting tool one kind of machine clip cutter which use indexable blade. That is, the pre-forming process and having a plurality of cutting edges of the polygon blade through mechanical clamping clamped on a tool. When a cutting edge weared in the course, as long as release the clamping elements, transfer, or replace the blade, so that the new cutting edge into the operative position, and then clamp the blade ,the cutter can continue to be used. [1] The Indexable blade are cutting parts of indexable cutter. Although there kinds of indexable cutting tools, but indexable blade is its essential parts, blade blunted, we just need simply index or replace the blade cutting can proceed. The R-blade in this is one king of dedicated blade which is used in the machine folder milling cutter for turbine large blade fork blade root structure. In the original process work longer hours, low productivity, is not conducive to mass production circumstances, and after the workshop production of a comprehensive analysis of the actual situation, through the improvement of the original process and machine dedicated fixture design, the use of mechanical manufacturing technology and related courses knowledge to solve R blade in the processing of positioning, clamping and routing arrangements and other aspects related issues, while ensuring machining quality, increase its production and proc
