高精度孔系框架类零件的精密加工

Precision Machining of Frame Parts With High Precision Holes

以具有较高同轴度和相交垂直度孔系的框架类零件为研究对象 ,抽象出有代表性的特征零件。

Among frame parts having precise holes (the requirement on whose co_axiality and cross _perpendicularity is high),representative parts are abstracted. The precision machining and measuring of these parts are analyzed.
