Abstract

The geometric accuracy of conventional machine tools is tested, in general, in accordance the principles proposed by Schlesinger ^, who established a system of test charts for a range of metal working machine tools. With the advent of NC and CNC machine tools, however, it has been found necessary to extend the basic Schlesinger tests which have now been incorporated in many National and International Standards. Certainly, up to the 1980's most standards on test conditions for machine tools, which represented most of the production of the MTE/1 (British Standards Institution [BSI]) and TC39 (International Organisation for Standardisation [ISO]) technical committees, only dealt with geometric accuracy and. in order to provide some information on the cutting performance, with finishing cuts. However, since that period, the emphasis has widened with the increased complexity of CNC and by de
