Abstract

Specifies the nomenclature appropriate to each part of the machine (in English and French, and the eqivalent terms in German, Spanish, Italian and Swedish) and the geomatrical tests for these turning lathes, and gives the corresponding permissible deviations which apply to machines of general purpose use and normal accuracy. It deals only with the verification of the accuracy of the machine. It does not apply to the testing of the running of the machine nor to its characteristics which should generally be checked before accuracy is tested. Does not impose any practical test.
