从分析异形铸件的加工工艺入手,介绍利用UG NX自上而下装配建模与自下而上装配相结合方式对其进行专用成套夹具三维设计到二维工程图的一般过程。
Starting with the analysis of the processing technology of profiled castings, this paper introduces the general process of using the three-dimensional design of the complete sets of fixtures to the two-dimensional engineering drawings with UG NX top-down assembly modeling and bottom-up assembly.
