This part of ISO 230 defines four tests, which are:

- an environmental temperature variation error (ETVE) test;

- a test for thermal distortion caused by rotating spindles;

- a test for thermal distortion caused by moving linear axes;

- a test for thermal distortion caused by rotary motion of components.

The tests for thermal distortion caused by moving linear axes (see clause 7) are applicable to numerically controlled (NC) machines only and are designed to quantify the effects of thermal expansion and contraction as well as the rotational deformation of structure. For practical reasons, the test methods described in clause 7 apply to machines with linear axes up to 2 000 mm in length. If they are used for machines with axes longer than 2 000 mm, a representative length of 2 000 mm in the normal range of each axis should be chosen for the tests.

The tests correspond to “drift test procedure” as described in A.4.2 of ISO/TR 16015, applied for machine tools.

This document specifies, with reference to ISO 230‐1 and ISO 230‐7, the geometric tests for general‐purpose, numerically controlled (NC) turning machines and turning centres with vertical workholding spindles, as well as the corresponding applicable tolerances.

This document explains different concepts or configurations and common features of NC turning machines and turning centres with vertical workholding spindles. It also provides a terminology and designation of controlled axes (see Figures 1, 2, 3, and 4).

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). Tests not concerning the geometric accuracy of the machine are dealt with in other parts of ISO 13041.
