This part of GB/T 23480 specifies, with reference to GB/T 17421.1—1998 and GB/T 17421.2—2000, geometric tests, tests of accuracy and repeatability of numerically controlled positioning axes and machining test for general purpose and normal-accuracy small hole high speed drilling electro-discharge machines. It also specifies the applicable tolerances, corresponding to the above-mentioned tests.
This part of standard is applicable to small hole high speed drilling electro-discharge machines, hereinafter referred to as machine.
This part of standard deals only with the verification of accuracy of the machine. It does not apply to the testing of the machine operation (vibrations, abnormal noises, stick-slip motion of components, etc.) or the checking of its characteristics (such as speeds, feeds, etc.), which should generally be checked before the testing of the accuracy.
This part of standard provides the terminology used for the principal components of the machine and t
