本文分析了发动机零件的结构特点,基于NX软件对两种建模方法进行了对比分析。并基于WAVE的关联工序建模方法,针对不同结构的发动机零件,给出了不同的建模思路。随着MBD技术在航空发动机行业的推广应用,设计部门开始采用全三维的发图模式向制造部门传递设计信息。依据纸质设计图编制二维工艺规程,指导现场生产的传统发动机零件工艺编制方式将面临严峻的考验。为了应对设计三维发图的形式,航空发动机制造部门开始研究三维工艺设计模
In this paper, the structural characteristics of engine parts are analyzed. Based on NX software, the two modeling methods are compared and analyzed. Based on the WAVE modeling method of association process, different modeling ideas are given for engine parts with different structures. With the MBD technology in the aviation engine industry promotion and application, the design department began to use full three-dimensional send model to the manufacturing sector delivery of design information. According to the paper design plan preparation of two-dimensional process rules, guide the site production of traditional engine parts technology preparation will face a severe test. In response to the design of three-dimensional map in the form of aero-engine manufacturing sector began to study the three-dimensional process design model
