摘   要

 
 在制定工艺过程中，要确定各工序的安装工位和该工序需要的工步，加工该工序的机车及机床的进给量，切削深度，主轴转速和切削速度，该工序的夹具，刀具及量具，还有走刀次数和走刀长度，最后计算该工序的基本时间，辅助时间和工作地服务时间。
本次设计的主要内容是泵体加工工艺规程及孔镗孔夹具和孔的钻孔夹具的设计。首先对泵体的零件进行分析，通过对泵体进行的研究和分析，描述了泵体零件的加工工艺的制定，各工序的加工工艺的分析以及切削用量和工时的计算等相关内容。为了提高劳动生产率，降低劳动强度，保证加工质量，与指导老协商后，觉得用夹具比较合适。

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 t can replace the heavy labor in order to achieve the production mechanization and automation, and can work in dangerous working environments to protect the personal safety, Therefore widely used in machine building, metallurgy, electronics, light industry and atomic energy sectors.of the direction, and only one direction 48 hole feed.This paper introduces the basic principle and the classification of interpolation, principle of point by point comparison method, the visual of development environment and drawing function introduction. Using the top framework of visual in of, based on the 12 hole developed a parabolic interpolation of point by point comparison method, which can further the understanding to the characteristics of point by point comparison method and the further understanding of the development tools, for the further numerical fields.Under the global economic development environment,China's various industries in other countries by the advanced technology of impact at the same time.
