适用范围：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 in-dividual types of cutting tool, such as single-points tools, twist drills, milling cutters and hand tools, can 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 in-cluded 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 can 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 per-forming 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 in-cluded 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 (NNI). However, only the terms and definitions given in the official languages can be considered as ISO terms and definitions.
