Machine tools — Conditions for testing the accuracy of bridge-type milling machines — Part 2: Travelling bridge (gantry-type) machines

Specifies the nomenclature used for the principal parts of the machine and the designation of the axes (in English, French and Russian and the equivalent terms in German and Italian) and the geometrical and practical tests for these milling machines, and gives the corresponding permissible deviations which apply to machines of general purpose use and normal accuracy. It deals only with the verification of the accuracy of the machine. It does not apply to the testing of the running of the machine nor to its characteristics which should generally be checked before the accuracy is tested.
