Abstract / scope
ISO 10791-10:2007 specifies, with reference to ISO 230-3, tests for the evaluation of thermal distortions of the machine structure and positioning system, up to 2 000 mm in length, of machining centres. It gives three test methods: environmental temperature variation error, thermal distortion caused by rotating spindle, and thermal distortion caused by moving linear axes.
There is no intention of assigning any numerical tolerances associated with the tests specified.
