YJS3箱座零件的加工工艺设计及数控加工程序
摘  要
箱座零件加工工艺及镗孔夹具设计是包括零件加工的工艺设计、工序设计以及专用夹具的设计三部分。在工艺设计中要首先对零件进行分析，了解零件的工艺再设计出毛坯的结构，并选择好零件的加工基准，设计出零件的工艺路线；接着对零件各个工步的工序进行尺寸计算，关键是决定出各个工序的工艺装备及切削用量。

Abstract
The box seat parts processing technology and fixture design is a boring process designing, including the parts processing process design and fixture three. In the process of design should first carries on the analysis to the components, parts of the process to understand the design of the structure and the choice of blank, processing base part, design part of the process route; and then on the part of every step of process dimension calculation, the key is to determine the craft equipment and the cutting dosage of each working procedure.
 
Keywords: process, process, cutting parameters
