Abstract

Machine tool manufacturers and users will be well versed in the determination of accuracy and repeatability of their machines according to the major national and international machine performance standards. These standards are concerned with measuring the repeatability and accurate positioning of moving parts of a numerically controlled (NC) machine along or around each of the linear and rotary axes in turn. Since the publication of the international standard some 9 years ago, coupled with the knowledge of many thousand machine tool calibration exercises world-wide and new recommendations from ISO Geneva, the working group (ISO / TC39 / SC2 / WG2) charged with revising the international standard made further wide-ranging recommendations on the subject of how to measure machine tool accuracy and repeatability. These recommendati
