Abstract

Up to the 1980s most standards on test conditions for machine tools, which represented most of the production of the MTE/1 (BSI) and TC39 (ISO) technical committees, were made following the same principle; they 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 demand from industry for different tests for assessing more thoroughly the machine performance. Also, ten years ago, over 90% of BSI's standards were purely national, today, the tables have turned with over 90% of BSI's standards being either dual numbered or harmonized with European or International standards. This paper describes the current status of the relevant BSI and ISO standards on machine tool testing and previews how, increasingly,
