Introduction
The purpose of this document is to standardize the inspection methods for conventional precision and general-purpose wire-cut EDM machines (one-way wire type).
In this document, the tolerances of G1, G2, G3, G4, P1, P2, P3, P4, P5 have changed compared with GB/T 19361-2003.
Wire EDM (one-way wire type)
Accuracy check
1 Scope
This document refers to ISO 230-1, ISO 230-2 and ISO 230-4 to specify general-purpose, conventional precision wire EDM machine tools
(One-way wire type) geometric accuracy inspection, CNC axis positioning accuracy and repeat positioning accuracy inspection, processing inspection and circle inspection. This document also
The tolerance value corresponding to the above-mentioned inspection is specified.
This document applies to cross-sliding table type machine tools and double-column type machine tools.
This document only relates to the verification of machine tool accuracy, and it is neither applicable to machine tool operation tests (such as vibration, abnormal noise, component crawling, etc.).
Inspection is also not applicable to the test of machine tool performance (such as speed, feed, etc.). The above-mentioned inspection is usually completed before the accuracy of the machine tool.
This document specifies the terminology of the main parts of machine tools and specifies the naming of coordinate axes with reference to ISO 841.

3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Electro-dischargemachines
The machine tool uses the pulse discharge method between two conductive electrodes (tool electrode and workpiece electrode) to ablate materials in the insulating working fluid.
The discharge is independent in time and randomly distributed in space, and the discharge energy of the two poles is controllable.
3.2
Wire electrical-dischargemachines
The machine tool uses the electrode wire to ablate material through EDM to manufacture prismatic or more complex shaped workpieces.
