两件轴套配合件
摘要
本文研究的是设计零件的工艺编制及编程,所用的图纸是学校指定的练习用图,设计零件的类型为轴类,加工设备的一般是以通用的数控车床为主。
首先分析设计零件的零件图,再介绍设计零件进行工艺编制时要注意的地方,然后确定毛坯形式,再对零件加工的工艺进行拟定、分析并对零件加工中的主要零件的工艺,对刀具的选择,切削用量的确定进行详细说明,最后再对零件的加工进行编程。
由于设计零件是轴类配合件,装夹时较难,加工难度大,它的精度要求又比较高。因此在安排工序的时候,需要注意各个工序的加工顺序及各工序加工时基准的选择。
关键词:工艺设计、编程、精度要求、数控车床
Abstract
In this paper, the process of designing parts and programming is studied, the drawing used is the practice drawing designated by the school, the type of design part is shaft class, the machining equipment is generally based on the general numerical control lathe.
The paper first analyzes the part drawing of the design part, then introduces the place that should be paid attention towhen the design part carries on the craft compilation, then determines the blank form, then carries on the formulation to the part processing technology, analyzes and carries on the technology to the main part in the part processing, The selection of cutting tools and the determination of cutting parameters are described in detail. Finally, the programming of the machining of the parts is carried out.
Because the design part is shaft fit, it is difficult to assemble and process, and its precision isvery high. Therefore,when arranging the process,we should pay attention to the processing sequence of each process and the selection of the standardwhen each process is processed.
Keywords: process design, programming, precision requirements, CNC lathe
