典型回转轴类零件数控车削加工工艺设计与编程
摘要
本文主要针对回转轴类零件工艺进行数控加工工行分析，它意义深重，本文将对它进行讲述。零件的工艺设计内容主要有零件加工工艺过程设计、加工工序设计、程序设计，以及机床、刀具、夹具的选择等等。重点分析了零件的数控加工工艺过和和所采用的程序结构，例如如何合理运用常用复合循环指令进行零件的粗加工、精加工程序的编制。此外，在加工设计过程中也展开了相应的讨论，并且得出了此类回转型零件的一般加工步骤。

Abstract
In this paper, rotating shaft parts for CNC machining technology of the bank analysis, it profound meaning, this articlewill be about it. Part of the process design the content of main machining process planning, machining process design, process design, and machine tools, tools, fixtures, etc. choices. Analyzed Machining of parts and used over and the program structure, such as the reasonable use of G71, G73, G70, G92 and other commonly used parts combined-cycle instructions roughing, finishing the program design. In addition, the design process has started processing the corresponding discussion, and come back transformation of such parts of the general processing steps.
Keywords: dimensional accuracy of process design programming
