- Scope
- With reference to GB/T 17421.1-1998 and GB/T 17421.2-2000, this standard specifies the geometric accuracy inspection, numerical control axis positioning accuracy and repeat positioning accuracy and processing test. This standard also stipulates the tolerance value corresponding to the above inspection. This standard applies to single-column machine tools and double-column machine tools of the cross table type. This standard only involves the inspection of machine tool accuracy, and is not applicable to the inspection of machine tool operation tests (vibration, abnormal noise, crawling of parts, etc.) or its parameters (such as speed, feed rate, etc.). before proceeding. This standard specifies the terms used for the main components of machine tools and specifies the nomenclature of the coordinate axes with reference to ISO 841-2001 (see reference [1]).
