This part of ISO 1701 specifies, with reference to ISO 230-1, both geometric and machining tests on general purpose, normal accuracy, horizontal-spindle milling machines with table of variable height. It also specifies the applicable tolerances corresponding to the above-mentioned tests.
NOTE Milling machines with table of fixed height are covered by ISO 1984.
This part of ISO 1701 deals only with the verification of accuracy of the machine. It does not apply to the testing of the running of the machine (vibration, abnormal noise, stick-slip motion of components, etc.), nor to machine characteristics (such as speeds, feeds, etc.), as such checks are generally carried out before testing the accuracy.
