摘要

工艺学是以研究机械加工工艺技术和夹具设计为主技术学科，具有很强的实践性，要求学习过程中应紧密联系生产实践，同时它又具有很强的综合性，
本次设计的课题是法兰盘加工工艺规程及某一工序专用夹具设计，主要内容如下：
首先，对零件进行分析，主要是零件作用的分析和工艺分析，通过零件分析可以了解零件的基本情况，而工艺分析可以知道零件的加工表面和加工要求。根据零件图提出的加工要求，确定毛坯的制造形式和尺寸的确定。
第二步，进行基面的选择，确定加工过程中的粗基准和精基准。根据选好的基准，制订工艺路线，通常制订两种以上的工艺路线，通过工艺方案的比较与分析，再选择可以使零件的几何形状、尺寸精度及位置精度等技术要求得到合理的保证的一种工序。
第三步，根据已经选定的工序路线，确定每一步的切削用量及基本工时，并选择合适的机床和刀具。对于粗加工，还要校核机床功率。
最后，设计第三道工序—设计夹具。先提出设计问题，再选择定位基准，然后开始切削力、夹紧力的计算和定位误差的分析。然后把设计的过程整理为图纸。
通过以上的概述，整个设计基本完成。

ABSTRACT
A specialized main specialized course that " mechanical manufacturing engineering is studied " is machinery , rely mainly on studying machining technology and jig to design technological discipline , have very strong practicality , require that should contact production practices closely in the learning process, at the same time it has comprehensive the very strong one,
The subject of this graduation project is that lathe ring flange processing technology rules and special-purpose jig of a certain process are designed, the main content is as follows:
First of all, analyse , it is mainly analysis of the function of the part and craft analysis to the part , through part analyse can find out about basic situation of part, and craft analyse may know the processing surface of the part and is it require to process. The processing demand put forward according to the part picture, confirm the manufacture form of the blank and sureness of the size.
The second step, carry on the choice the base , confirm thick datum and precise datum in the processing course. According to the datum chosen , make the craft route , usually make the craft route of more than two kinds, with analysing through the comparison of the craft scheme, and then choosing be able to make such specification requirements as the precision of geometry form , size of the part and precision of position ,etc. get a kind of process of the rational assurance s.
The third step, according to the already selected process route, confirm for every steps of cutting consumption and basic man-hour , choose suitable lathe and cutter. To rough machining , will check the power of the lathe .
Finally , design the third process - the jig getting into the hole of the ring flange. Put forward the question of designing first , and then choose to orient the datum , then the calculation that begins to cut strength , clamp strength and analysis of the localization error. Then put the design course in order as the drawing.
Through the summary of the above, design and finish basically entirely.

1绪论
设计是我们在学完大学的全部课程后进行的，是我们对大学四年的学习的一次深入的综合性的总考核，也是一次理论联系实际的训练，这次设计使我们能综合运用机械制造工艺学中的基本理论，并结合实习中学到的实践知识，独立地分析和解决工艺问题，初步具备了设计一个中等复杂程度零件的工艺规程的能力和运用夹具设计的基本原理和方法，拟订夹具设计方案，完成夹具结构设计的能力，也是熟悉和运用有关手册、图表等技术资料及编写技术文件等基本技能的一次实践机会。因此，它在我们大学生活中占有重要地位。就我个人而言，我也希望通过这次设计对自己未来将从事的工作进行一次适应性心理，从中锻炼自己分析问题，解决问题的能力，对未来的工作发展打下一个良好的基础。由于能力所限，设计尚有许多不足之处，恳请各位老师给予指教。
