Foreword Iso (the International Organization for Standardization) is a worldwide federation of national standards bodies (iSO member bodies). The work of preparing International Standards is normally carried out through ISO'technical committees. Every member body interested in a subject for which a technical committee has been established has mentai and non-governmentai, in iaison with iso, aiso take part in the work. the member bodies for approval before their acceptance as International Standards by least 75 % approval by the member bodies voting. International Standard ISO 3002/3 was prepared by Technical Committee ISO/TC 29 Smalltools. ?

IS0 3002/1 under the following clauses as indicated: primary motion, see 3.6.1 Scope and field of application direction of primary motion, see 3.6.1.1 This International Standard defines a nomenclature for certain cutting speed vc, see 3.6.1.2 basic concepis concerning the machining and grinding of feed motion, see 3.6.2 materials. This part of Iso 3002 deals specifically with direction of feed motion, see 3.6.2.1 geometric and kinematic quantities in cutting. It should be read in conjunction with part 1 of this International Standard which feed speed Vt, see 3.6.2.2 is more general. resultant feed motion, see 3.6.3 It is generally applicable to all machining operations, including resultant cutting speed Ve, see 3.6.3.2 grinding. For grinding however, several additional geometric NOTES and kinematic quantities are defined in IS0 3002/5. Definitions of all concepts mentioned or used in this part of The definitions are divided into six main clauses which deal ISO 3002 are printed in italics; they can be found either in the body of with feed, cutting edge and related quantities, engagement, this part or in part 1, to which the reader is referred. the cut and its dimensions, the pass and its dimensions, and Ail quantities defined in IS0 3002/1 may vary in time: they are thematerialremovalraterespectively defined and should be measured as instantaneous quantities at a cer- tain instant in time, unless clearly specified otherwise.
