NBN ISO 13041-1:2021

This document specifies, with reference to ISO 230-1, the geometric tests on normal accuracy numerically
controlled (NC) turning machines and turning centres with horizontal work spindles as defined in 3.1
and 3.2. It also specifies the applicable tolerances corresponding to the above-mentioned tests.
Where applicable, this document also applies to horizontal spindle turret and single spindle
automatic lathes.
This document explains different concepts or configurations and common features of NC turning
machines and turning centres. It also provides a terminology and designation of controlled axes.
This document deals only with the verification of the accuracy of the machine. It does not apply to the
operational testing of the machine (e.g. vibration, abnormal noise, stick slip motion of components) nor
to machine characteristics (e.g. speeds, feeds) as such are checks generally carried out before testing
the accuracy.
