文档介绍：CA6140型普通车床刀架中部转盘机械加工工艺规程
摘要
在机械加工中使用着大量的夹具,用以安装加工对象,使之占有正确的位置,以保证工件的加工质量。
根据零件本身的特点、生产类型以及零件在具体工作时的作用选择工艺规程和夹具。在工艺规程方面:通过对普通车床的研究对刀架中部转盘及工艺参数采取一个优化策略,研制一个好的转盘。从而缩短生产周期,降低制造成本,提高加工精度,延长刀具寿命,而且依据优化了的工艺及刀具参数,可以建立或完善高速切削工艺数据库,将切削工艺实践中积累的合理选择切削参数与刀具的经验和数据收集起来,为现场加工提供准确及优化的高速切削数据,从而更大程度上提高切削加工水平,获得更大的经济利益;在夹具设计方面,因为是盘类零件,加工两侧面,选择立式铣床加工,考虑诸多因素拟订最优方案:有效的减少工件加工的基本时间和辅助时间、提高劳动生产率、有效减低工人劳动强度,最终完成本次设计。

Abstract
In machining use a large number of fixture to install processing object, to have the correct position, to ensure that the processing quality.
According to the characteristics of itself, production parts and parts in the specific work type the role of selection process planning and fixtures. In the process planning aspects: based on the research of the ordinary lathe tool central wheel and the process parameters to take a optimization strategy, developed a good turntable. So as to shorten the production cycle, reduce manufacturing costs and improve machining precision and extend the life of cutter, and based on the optimization of process parameters and tools. Can establish or perfect process database high-speed cutting, cutting process will accumulate in practice the reasonable selection of cutting parameters of the tool and the experience and data collected, and the processing to provide accurate and optimization of high speed cutting data, more degree increase cutting processing level and get more economic interests;The fixture design, because it is dish parts processing, two side, choice of vertical milling machine, so considering many factors draw up the optimum scheme: reduce the processing of prime time and auxiliary time, improve labor productivity, reduce labor intensity, plete the design.
Key words: turntable;Making up the process of machine workmanship;Special jig design
