Machining accuracy depends not only on geometric precision, but also on machine tool spindle error motions. This is particularly important for machining with high rotational speed. Spindle error movements are precisely defined and the method of their measurement methodology is standardized (ISO 230-7 and B89.3.4). Also devices for measuring the error movements are generally known. The main problem is the development of algorithms to ensure the proper measurement, interpretation accordingly to the standards, especially considering so called sensitive and non-sensitive directions. This paper presents an approach and algorithms of spindle errors movements measurement. The proposed methodology is more reliable than commercial solutions.
