ISO 3070-2:1997 PDF

Scope: This part of ISO 3070 specifies, with reference to ISO 230-1 and ISO 230-2, geometric tests, tests and tests for checking accuracy and repeatability of positioning by numerical control, on general purpose, normal accuracy, table type boring and milling machines with horizontal spindle. These types of machine tools are defined in sub-clause 3.1 of ISO 3070-0:1982. This part of ISO 3070 also specifies the applicable tolerances corresponding to the above mentioned tests. These machines can be provided with spindle heads of different types corresponding in most cases to figures: 4(spindle head with sliding boring spindle and milling spindle) 5(spindle head with sliding boring spindle and with facing head) 6(spindle head with ram or milling ram) of ISO 3070-0:1982. In addition, it should be noted that this part of ISO 3070 concerns machines which have both longitudinal (W-axis) and transverse (X-axis) movement of the table, a vertical movement of the spindle head (Y-axis) and may include a rotary or indexing table. This International Standard deals only with the verification of the 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.
