BS 4361-14:1988

Accuracy, geometrical tests and terminology.

This International Standard specifies the nomenclature appropriate to each part of the machine and, with reference to ISO 230-1, the geometrical tests for routing machines, and gives the corresponding permissible deviations which apply to machines of general purpose use and normal accuracy.

NOTE In addition to terms used in the three official ISO languages (English, French and Russian), this International Standard gives the equivalent terms in the German, Spanish, Italian and Swedish languages in an Annex; these have been included at the request of Technical Committee ISO/TC 39 and are published under the responsibility of the member bodies for Germany, F.R. (DIN), Spain (IRANOR), Italy (UNI) and Sweden (SIS). However, only the terms given in the official languages can be considered as ISO terms.

This International Standard deals only with the verification of the accuracy of the machine. It does not apply to the testing of the running of the machine (vibrations, abnormal noises, stick-slip motion of the components, etc.), nor to its characteristics (speeds, feeds, etc.) which should generally be checked before the accuracy is tested.

This International Standard does not impose any practical test. For routing machines, practical tests are an exception and need be performed only where there is prior agreement between the manufacturer and the user.

This International Standard applies to those machines designated by the number 12.315.12 in ISO 7984.

The Annex does not form an integral part of this International Standard.
