Test conditions for machining centres - Evaluation of thermal distortions Ingestion-build-143074 BS 5106 on ‘spiral anti-extrusion1 Scope This part of ISO 10791 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 a rotating spindle; thermal distortion caused by moving linear axes. There is no intention of assigning any numerical tolerances
