设计简介
缸体的加工质量将直接影响机器的性能和使用寿命。本次设计旨在提高缸体的加工效率，由此我们首先对缸体的结构特征和工艺进行了仔细的分析，然后确定了一套合理的加工方案，加工方案要求简单，操作方便，并能保证零件的加工质量。全文加工工艺规程分为五个部分，第一部分为分析零件，简单介绍零件的
作用和工作原理；第二部分为选择毛坯；第三部分为设计工艺规程：包括制定工艺路线，选择基准面等；第四部分为工序设计：包括选择机床，确定加工余量，工序尺寸及毛坯尺寸，确定切削用量及计算基本工时等；第五部分为编制工艺文件。

Abstract
Cylinder machine processing quality will directly affect the performance and service life. The cylinder is designed to improve processing efficiency, this we first of all the structural features of the cylinder and the process was carefully analyzed, and then determine a reasonable processing program, processing program requires simple, easy, and can ensure machining quality. Full-text processing of order is divided into five parts, the first analysis of the parts, a brief parts the role and working principle; second part selection blank; third part design process planning: including the development of process route, select datum, etc.; fourth part is the design process: including the selection of machine tools, determine the allowances, working finally size, determine the amount and calculation of cutting the basic working hours; the fifth part of the process for the preparation of documents.
