The aim of this part of ISO 3002 is to apply the basic terminology defined in ISO 3002, parts 1 to 4, specifically
to grinding operations and to define additional quantities specific to grinding.
NOTE — In addition to terms used in the three official ISO languages (English, French and Russian), this part of ISO 3002
gives the equivalent terms in the German, Italian and Dutch languages; these are published under the responsibility of the
member bodies for Germany, F. R. (DIN), Italy (UNI), the Netherlands (NNI) and Belgium (IBN). However, only the terms
given in the official languages can be considered as ISO terms.
For the purposes of this part of ISO 3002 the meaning of the word grinding is considered in a limited sense as
a material removal operation in which the tool is a grinding wheel.
The primary motion
1) is the rotation of the grinding wheel which causes a considerable peripheral speed in
the contact area with the workpiece.
A feed motion
1) is applied to the tool or workpiece to obtain a continuation of the removal of workpiece material
in the form of small chips by the action of individual cutting edges
1).
The feed motion may consist of several components. The machine surface is generated by the combined effect
of the shape of the grinding wheel and the path of the motion components.
