文档介绍：摘要
在机械设计中，采用各种机械加工方法将毛培加工成零件，再将这些零件装配成机器。其中使各种材料、半成品成为产品的方法和过程，则称为工艺。本次毕业设计的课程是中间齿轮加工工艺，主要内容如下：
首先，进行零件的分析，主要是零件作用的分析和工艺分析。根据零件图提出的加工要求，确定毛胚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第一种工序。
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***。对于粗加工，还要校核机床功率。
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分析。然后把设计的过程整理为图纸。
通过上述，整个基本设计完成。

Abstract
Through using the gearbox，all kinds of mechanical processing method will gross-pui processed into parts, then these parts assembled into the machine. Method of making all kinds of materials, semi-finished products and processes, it is called a process. The course of this graduation design is the intermediate gear processing technology, the main contents are as follows
First of all, on the analysis of the parts, mainly the parts function analysis and process analysis. According to part drawing processing requirements, determine the determination of hair embryo shape and size of manufacturing.
The second step, select the base surface, determine the crude benchmark in the process of machining and fine benchmark. According to choose good benchmark, make two or more of the process route, through the comparison and analysis of technological scheme, then choose can make the parts of the accuracy of the geometric shape, size and the location precision technology for the first step of reasonable assurance.
The third step, according to the already selected process route, determine the cutting parameter and basic man-hour of each step, and choose the suitable machine tools and cutting tools. For rough machining and checking machine power.
Design questions, and then select locating datum, and then start cutting force, clamping force calculation and the analysis of positioning error. Then the design process for drawings.
Through the above, the basic design completed
Key words: intermediate gear, process design, fi
