ISO 8636-2:2007 specifies, with reference to ISO 230-1, ISO 230-2, and ISO 230-7, geometric tests, machining tests, and tests for checking accuracy and repeatability of positioning of numerically controlled axes for general-purpose normal accuracy bridge-type milling machines with a travelling bridge (gantry-type). ISO 8636-2:2007 also specifies the applicable tolerances corresponding to the above-mentioned tests.
ISO 8636-2:2007 is applicable to machines with travelling bridge and fixed table. It does not include single-column (open sided) machines and those with fixed bridge and moving tables.
ISO 8636-2:2007 deals only with the verification of the accuracy of the machine. It does not apply to the testing of the machine operation (vibration, abnormal noise, stick-slip motion of components, etc.) nor to machine characteristics (such as speeds, feeds, etc.), which should generally be checked before testing the accuracy.
ISO 8636-2:2007 provides the terminology used for the principal components of the machines and the designation of the axes with reference to ISO 841.
