This International Standard defines a nomenclature for certain basic concepts concerning the machining and
grinding of materials. This part of ISO 3002 establishes and defines those terms used for forces, energy and
power in connection with cutting. It should be read in conjunction with ISO 3002/1 which is more general.
It is generally applicable to all machining operations, including grinding. Flowever certain terms specifically
for grinding are defined in ISO 3002/5.
The definitions
1) are divided into five main clauses: the first two deal with forces and torques exerted by a tool
or by the cutting part on the workpiece, the next two are concerned with energy and power for a particular
operation on a specific machine tool, and the last gives details of individual quantities where these may differ
from the basic quantities.
NOTE — In addition to the terms given in the three official ISO languages (English, French, Russian), this part of ISO 3002
gives the equivalent terms in German, Italian and Dutch; these terms have been included at the request of Technical
Committee ISO/TC 29, and are published under the responsibility of the committee members for Germany, F.R. (DIN),
Italy (UNI) and the Netherlands (NNI). However, only the terms given in the official languages can be considered as ISO
terms.
