本文以航空发动机某典型对开机匣为例,介绍了航空机匣的主要结构特点,并简单介绍了NX软件在机匣类零件上经常使用的同步建模和多轴铣加工两个典型的设计和加工模块。通过NX同步建模功能对该典型零件数控模型修改的应用实例,以及多轴铣加工模块在零件外型大面和清根加工的应用实例,论述了NX软件在机匣加工工序模型创建和多轴数控程序编制中高效的实用性。
In this paper, taking a typical aero-engine splitter box as an example, the main structural features of aero-box are introduced, and two typical designs of synchronous software and multi-axis milling And processing module. Through the application of the NX synchronous modeling function to the modification of the typical part NC model and the application example of the multi-axis milling module in the machining of large parts and clear roots of parts, Axis CNC programming in the efficient and practical.
