摘　　要：公司新型发动机缸盖火花塞孔使用了三维空间角的设计,车间五轴机床加工基准和图纸基准不一致,本文将提供一种三维空间角从图纸基准到加工基准的转换方法,这种方法使用Unigraphics NX实现,直观便捷,省去繁琐的计算过程,能解决复杂产品中不同基准下尺寸转换的问题。The company's new engine cylinder head spark plug hole uses a three-dimensional space angle design.Workshop 5-axis machine tool processing reference and drawing reference are inconsistent.This paper will provide a method for converting the three-dimensional space angle from the drawing reference to the machining reference.This method is realized by Unigraphics NX,which is intuitive and convenient,saves the tedious calculation process,and can solve the problem of size conversion under diff erent standards in complex products.

关 键 词：三维空间角 尺寸转换 Unigraphics NX
