Abstract

In recent years British and International standards have been expanded to cover most aspects of machine tool calibration. Standards now exist for straightness and angular calibration as well as the more conventional linear positioning calibration. Although the standards provide comprehensive guidelines for measurement and analysis of the individual error components they do not define how these errors will affect machine performance. Angular errors in particular are difficult to quantify in terms of how they will affect machine tool accuracy, as this is a function of a numb
