摘要：本篇设计是沉降片加工工艺设计及组织性能分析。沉降片零件的主要加工表面是上下左右表面几各圆弧缺口部位和孔在加工。一般来说，保证平面的加工精度与保证孔系的加工精度相比，保证平面的加工精度比较容易。孔径加工都是选用专用钻夹具，夹紧方式一般选用手动夹紧，夹紧可靠。因此生产效率较高。能够满足设计要求。

文章的重点在于对沉降片的工艺性和力学性能分析，对加工工艺进行合理分析，选择确定合理的毛坯、加工方式，并对其组织性能进行分析，对沉降片应在何种组织状态下使用作出准确的结论，经过实践证明，这一课题在选择对后续在类似零件在加工工艺在制定和组织性能在分析是有现实意义的。

Abstract：Enable producing the target in process of production raw materials, the blank , state of quality and quantity on part become always  take place direct course of change ask craft course, if the blank is made, machining, heat treatment , assemble etc. and call it the craft course. In the course of making the craft , is it confirm every erector location and worker step that process need this of process to want, the locomotive of processing , this process , and the entering the giving amount of the lathe, cut depth , the rotational speed of the main shaft and speed of cutting, the jig of this process.
At present, part of the processing of domestic have begun to close to the  machine tool, but also need to clamp the workpiece, that is to say, although the technology has been greatly improved but his nature has not changed much, on the flip side, because of his skill and precision is high, so a high quality tool holder of  machine tools is an absolute necessity. As everyone knows, because our technology in the unceasing development, technical requirements for processing of the knife is also more and more high.
