This standard specifies the geometric accuracy inspection, CNC axis positioning accuracy and repeated positioning accuracy inspection, and machining inspection of CNC reciprocating wire electric discharge wire cutting machine tools formed in one cutting process. It also specifies the tolerance values corresponding to the above inspections. This standard also specifies the names of the main components of machine tools and names the coordinate axes in accordance with GB/T19660-2005. This standard is applicable to CNC reciprocating wire EDM machine tools formed by one-time cutting, including cross table single column machine tools and double column machine tools (hereinafter referred to as machine tools). The following normative references are essential for the application of this document. For dated references, only the dated version applies to this document. For undated references, the latest version (including all modification orders) applies to this document.
