摘　要
  设计内容：设计圆周支座零件的机械加工工艺规程及工艺装备，并绘制零件图、毛坯图、夹具装配图，填写工艺卡片，编制课程设计说明书。
设计意义：机械制造工艺课程设计是在全部学完机械制造工艺学及机床夹具设计课程，并进行了生产实习的基础是进行的一个教学环节。它要求学生全面地综合运用本课程及其有关先修课程的理论和实践知识进行工艺及结构的设计，也为以后做好毕业设计进行一次预备训练。

 
               ABSTRACT
  This topic is mainly design that designs the circular bearing to process the craft and tongses, adopting to design first in the design circular bearing processes the craft at according to process the craft to select by examinations the tongs of the project of the design and concrete design of the tongs;But the point of design is the design of the tongs.Because bore 17 of accuracy have high request, and position the size error margin small, for guarantee the position of the bore and process the accuracy we certainly at process the bottom to face of time pass to draw the line to find out the bottom to face of process the amount of remaining.Thus can with better assurance bore 17 of position and process the accuracy!Process the bore 14 of tongs was in processing the foundation that the bottom faces the furniture to add one 45 degrees of gradient plank in fact.Process the bore 17 of time is opposite for assurance to run parallel with B face of in the A we have to design accurately with the AN and B faces to settle for of tongs!Return in consideration of a degree of the work piece and the error margin of the cylinder degrees are small, the furniture that we design have to the bore 17 of tongs fixed position is accurate, and process the vibration of time small, that have to in the bore 17 of neighborhood seek a fixed position to step up the point!
