This part of ISO11090 specifies, with reference to ISO230-1 and ISO230-2, geometric and machining tests and tests for checking accuracy and repeatability of numerically controlled positioning axes for normal accuracy and general-purpose die sinking electro-discharge machines (die sinking EDM). It also specifies the applicable tolerances corresponding to the above-mentioned tests.
This part of ISO11090 is also applicable to single-column machines of cross-slide table type and fixed table type.
This part of ISO11090 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 to the checking of its characteristics (such as speeds, feeds, etc.), which should generally be checked before the testing of the accuracy.
This part of ISO11090 provides the terminology used for the principal components of the machine and the designation of the axes with reference to ISO841:2001.
NOTE In addition to the terms used in the official ISO languages (English and French), AnnexA of this part of ISO11090 gives the equivalent terms in the Dutch, German, Italian, Swedish, Persian, and Japanese languages. These are published under the responsibility of the national member bodies for Netherlands (NEN), Germany (DIN), Italy (UNI), Sweden (SIS), Iran (ISIRI), and Japan (JISC). However, only the terms given in the official languages can be considered as ISO terms.
