TS ISO 3002-1

This Part of ISO 3002 defines a nomenclature for certain basic
concepts concerning cutting tools; it is applicable to the
geometry of every kind of cutting tool and emphasizes a known
terminology for them which is intended to provide a framework
on which the nomenclature and appropriate Standards for individual
types of cutting tool, such as Single-Points tools, twist
drills, milling Cutters and hand tools, tan be established.
However, the Standards for individual types of cutting tool will
not each require or use the full range of terms and definitions
set out in the basic nomenclature established in this Part of
ISO 3002.
The definitions are grouped into four clauses. After defining the
general terms for surfaces on the workpiece, certain elements
of the tool, surfaces on the tool, the cutting edges and the tool
and workpiece motions in clause 3, this Part of ISO 3002
defines, in clause 4, reference Systems of planes which are
subsequently used to define the .various angles which are included
in clause 5. Two reference Systems of planes are
necessary : one, the tool-in-hand System, is used to define the
geometry of the tool so that it tan be manufactured and
measured; the other, the tool-in-use System, is required to
define the effective geometry of the tool when it is actually performing
the cutting Operation. Clause 7 gives definitions
relating to chip breakers.
ISO 3002/2 gives general conversion formulae to relate tool and
working angles.
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 German, Italian and Dutch; these have been included
at the request of ISO Technical Committee 29 and are published
under the responsibility of the member bodies for Germany, F.R.
(DIN), Italy (UNI) and the Netherlands (NN% However, only the terms
and definitions given in the official languages tan be considered as ISO
terms and definitions.
