1 Scope and field of application

This Fart of iSO 3002 defines a nomenclature for cartain basic concepts concerning cutting tools; it is applicable to the geometry of every kind of cutting tool and emphasizes a known terminologyfor 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 end 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 IS0 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 end the tool and workpiece motions in clause 3, this Part of IS0 XI02 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 tiefine 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 performing the cutting operation. Clause 7 gives definitions relating to chip breakers.

IS0 3002/2 gives general conversion formulae to relate tool and working angles.

NOTE - In addition to terms used in Ihe three official IS0 languages (English, French and Russian), this Part of IS0 3002 gives the equivalent terms in German, Italian and Dutch; these have been included at the request of IS0 Technical Committee 29 and are puMished under the responsibility of the member bodies for Germany, F.R. (DIN), Italy (UN11 and the Netherlands (NNI). However, only the terms and definitions given in the official languages can be considered as IS0 terms and definitions.

3 General terms

3.1 Surfaces on the workpiece

3.1.1 work surface (figure 1) : The surface on the workpiece 10 be removed by machining.

3.1.2 machined surface (figure 1) : The desired surface produced by the action of the cutting tool.

3.1.3 transient surface (figure 1) : The part of the surface which is formed on the workpiece by the cutting edge (3.4.1) and removed during the following cutting stroke, during the following revolution of the tool or workpiece, or by the following cutting edge.

3.2 Tool elements

3.2.1 body (figures 3 to 5) : The part of the tool which holds the cutting blades or inserts, or on which are formed the cutting edges (3.4.1).

3.2.2 shank (figures 2a, 4 and 5) : The part of the tool by which it is held.

3.2.3 tool bore (figure 3) : That bore in a tool by which it can be located and fixed by a spindle, arbor or mandrel.

3.2.4 tool axis (figures 3,4 and 5) : An imaginary straight line with defined geometrical relationships to the locating surfaces used for the manufacture and sharpening of the tool and for holding the tool in use. Genemlly, the tool axis is the centreline of the tool shank or bore; it is usually parallel or perpendicular to the locating surfaces, although it could be the centreline of a conical surface as in the case of a taper shank. When not ob- vious, the tool axis must be defined by the designer.

3.2.5 cutting part (figure 2a) : The functional part of parts of the tool each comprised of chip producing elements; the cutting edges (3.4.1). face (3.3 1) and flank (3.3.2) are therefore elements of the cutting pert.

In the case of a multi-toothed cutter, each tooth has a cutting L part.

3.2.6 base (figures 2a, 12 and 18) : A flat surface on the tool shank, parallel or perpendicular to the tool reference plane t4.1 .l), useful for locating or orienting the tool in its manufacture, sharpening and measurement.

Not all tools have a clearly defined base.

3.2.7 wedge (figures 3 and 7) : The portion of the cutting part enclosed between the face (3.3.1) and the flack (3~3.2). It can be associated with either the major or minor cutting edge (3.4.1).

IS : 11522 (Part l)-1886 IS0 3002/l-tW2

3.3 Tool surf~es 3.3.3.2 flank profile (figure 2d) : The curve formed by the

intersection of flank A, with any desired plane. Normally this Each tool surface is provided with a symbol consisting of the

letter A with a suffix indicating the identity of the surface (for

example Ay, the face). When it is necessary to distinguish

clearly a surface associated with the minor cutting edge

(3.4.1.2) theappropriate symbol bears a prime (for example A,’ , the minor flank).

profile is defined and measured in the cutting edge normal

plane P, (4.15). If it is to be defined in any other plane this must be clearly specified.

3.4 Cutting edges

3.3.1 face Ay (figures 2a, 3, 4, 5 and 7) : The surface or sur-

faces over which the chip flows. When the face is composed of

a number of surfaces inclined to one another, these are designated first face, second face, etc, starting from the cut-

ting edge. These surfaces may be called lands and unless other-

wise specified it is assumed that these are associated with the

major cutting edge (3.4.1 .l).

Where it is necessary to distinguish the faces associated with

the major and minor cutting edges (3.4.1.1 and 3.4.1.21, that

part of the face which intersects the flank (3.3.2) to form the

major cutting edge is called the major face and that part of the

face which intersects the flank to form the minor cutting edge is called the minor face, for example major first face, minor first

face, etc.

3.4.1 cutting edge : That edge of the face which is intended to perform cutting.

3.4.1.1 tool major cutting edge S (figures 2a, 3, 4, 5 and

7) : That entire part of the cutting edge which commences at

the point where the tool cutting edge angle K, is zero (5.1.1.1)

and of which at least a portion is intended to produce the tran-

sient surface on the workpiece. In the case of tools having a

sharp corner (3.4.21 at which the value of K, may be considered

to pass through zero, the major cutting edge commences at

that corner. In the case of tools for which the value of K, does

not decrease to zero at any point on the cutting edge, the entire

cutting edge is the tool major cutting edge as, for example, in the case of a slab milling cutter.

3.3.1.1 reduced face A, (figure 2c) : A specially prepared surface or surfaces separated from the rest of the face by a step

and designed in such a way that the chip contacts only the

reduced face.

NOTE - A reduced face should not be confused with the land associated with a groove or step intended to induce chip breaking nor with multiple faces of the tool. The symbol A, has been adomed to designate the reduced face and to distinguish it from lands on the tool face which are designated by A,,,, A,Q, etc.

3.3.1.2 chip breaker (see clause 7) : A modification of the

face A,,, to control or break the chip, consisting of either an integral groove or an integral or attached obstruction.

3.3.2 flank A, (figures 2a. 3, 4, 5 and 7) : The tool surface or

surfaces over which the surface produced on the workpiece

passes. When a flank is composed of a number of surfaces in-

clined to one another, these are designated first flank, second flank, etc., starting from the cutting edge. These surfaces may

be called lands and unless otherwise specified it is assumed

that these are associated with the major cutting edge (3.4.1.1 I.

Where it is necessary to distinguish the flanks associated with the major and minor cutting edges (3.4.1 .l and 3.4.1.2). that

part of the flank which intersects the face to form the major

cutting edge is called the major flank and that part of the flank

which intersects the face to form the minor cutting edge is

called the minor flank, for example major first flank, minor first

flank, etc.

3.4.1.2 tool minor cutting edge S’ (figures 2a, 3,4 and 5) : The remainder of the cutting edge, if any, and where present

commences at the point on the cutting edge where K, is zero

15.1.1.1) but extends from this point in a direction away from

the tool major cutting edge. It is not intended to produce any of the transient surface on the workpiece. Some tools may have

more than one tool minor cutting edge as, for example, in the

case of a cutting-off tool.

3.4.1.3 working major cutting edge S, (figure 2b) : That entire part of the cutting edge which commences at the point

where the working cutting edge angle K,~ is zero (5.2.1.1) and of which at least a portion produces the transient surface on

the workpiece. In the case of tools having a sharp corner (3.4.2)

atwhich the value of K,, may be considered to pass through

zero, the working major cutting edge commences at that cor-

ner. In the case of tools for which the value of K,, does not

decrease to zero at any point on the cutting edge, the entire

cutting edge is the working major cutting edge as, for example,

in the case of a slab milling cutter.

3.4.1.4 working minor cutting edge S,’ (figure 2b) : The

remainder of the cutting edge, if any, and where present com-

mences at the point on the cutting edge where K,~ is zero,

(5.2.1.1) but extends from this point in a direction away from

the working major cutting edge. It does not produce any of the

transient surface on the workpiece. Some tools may have more

than one working minor cutting edge, as for example, in the

case of a cutting-off tool.

3.3.3 Profiles of the face and flank

3.3.3.1 face profile (figure 2dl : The curve formed by the in tersection of the face A, with any desired plane. Normally this

profile is defined and measured in the cutting edge normal

plane P, (4.1.5). If it is to be defined in any other plane this must be clearly specified.

NOTE - A distinction must be made between the tool major cutting

edge and the working major cutting edge because the points at which

~~ ad 6e can be considered to be zero are not, In general. coincident.

3.4.1.5 active cutting edge (figure 2b) : That portion of the

working cutting edge which is actually engaged in cutting at a particular instant generating both the transient and machined surfaces on the workpiece.

3

IS : 11522 (Part l)-1886 IS0 3002/1-l 982

3.4.1.5.1 active major cutting edge S, : The portion of the active cutting edge measured along the cutting edge from the point of intersection of the cutting edge and work surface to the point on the working cutting edge at which the working cutting edge angle K~ (5.2.1.1) may be considered to be zero.

3.4.1.5.2 active minor cutting edge S,’ : The portion of the active cutting edge measured along the cutting edge from the point at which the working cutting edge K,, 62.1 .I) may

be considered to be zero to the point of intersection of the working minor cutting edge and the machined surface.

3.4.2 corner (figures 2 to 6a) : The relstively small portion of the cutting edge at the junction of the major and minor cutting edges; it may be curved, straight or the actual intersection of these cutting edges.

3.4.2.1 rounded corner (figure 6a) : A corner having a curved cutting edge.

3.4.2.2 chamfered corner (figure 5a) : A corner having a straight cutting edge.

3.4.3 selected point on the cutting edge : A point selected on any part of the cutting edge in order to define, for example, the tool or working angles at that point (5). The selected point may be on the major cutting edge or on the minor cutting edge. When the selected point is so chosen as to be ldc8ted on the minor cutting edge, the planes and angles associeted with this point are so designated (4 8nd 5).

3.4.4 rounded cutting edge : A cutting edge which is formed by 8 rbundd transition between the face, A,, and the flank, A,.

3.45 interrupted cutting edge (figure 6b) : A cutting edge having discontinuities of sufficient magnitude 8s to prevent chip formation from taking place 8t the locations where they occur. (Such discontinuities are often used to reduce the &ze of the individual chips produced by 8 tool such as 8 slab milting cutter. 1

3.4.6 tool profile : The curve formed by the orthogonal projection of the tool cutting edge, S, on any desired plane. Nor- mally this profile is defined 8nd measured in the tool reference

plane P, (4.1.1). If it is to be defined in another plane, this shall be clearly specified.

3.5 Dimensions

The dimensions of the cutting edges are measured in the con- ventional manner but additional definitions are required and are given below.

3.5.1 corner radius rC (figure 58) : The nominal radius of a

rounded corner measured in the tool reference pi&e, P, (4.1 .l).

3.5.2 chamfered corner length b, (figure 5a) : The nominal length of a chamfered corner measured in the tool reference plane P, (4.1.1).

3.5.3 land width b, and b, (figure 71 : The width of a land on the major face is designated by b, and the width of a land on the minor face is designated by b,,’ .

The width of 8 land on the major flank is designated by 0, and the width of a land on the minor flank is designated by 0,’

The identification number of the land together with the suffix used to identify the plane of measurement may be added if necessary, for example, bvn2, !I,,,, f~,,’

3.54 rounded cutting edge radius fn: The nominal radius of a rounded cutting edge measured in the cutting edge normal plane, P, (4.1.5).

3.5.5 width of reduced face $, (figure 2c) : The width of a

reduced face is designated by 0, and is measured in the cutting

edge normal plane P, (4.1.5). If it is to be defined in any other plane this must be specified clearly : the suffix indicating the plane of measurement should be added to the basic symbol, i.e. ?&.

NOTE - The width of a reduced face should not ba confused with the width of a land on the face. The symbol FY has been adopted to designate the width of a reduced face to distinguish it from the width of a land on the face which is designated by b,.

3.6 Tool and workpiece motions

All motions, directions of motions and speeds are defined

relative to the workpiece.

3.6.1 primary motion : The main motion provided by a

machine tool or manually, to cause relative motion between the

tool and workpiece so that the face of the tool approaches the

workpiece material. In a lathe, this motion is provided by the rotary motion of the workpiece; in drilling and milling

machines, it is provided by the rotary motion of the tool; in a planing machine it is provided by the longitudinal motion of the

table. The primary motion is only able to cause chip removal for more than one revolution or stroke if there is a feed motion as

defined in 3.6.2.

Usually, the primary motion absorbs most of the total power re-

quired to perform a machining operation.

3.6.1.1 direction of primary motion (figures 6 to 11) : The direction of instantaneous primary motion of the selected point

on the cutting edge relative to the workpiece.

3.6.1.2 cutting speed vc (figures 8 to 1 II : The instantaneous velocity of the primary motion of the selected point on the cutting edge relative to the workpiece.

3.6.2 feed motion : A motion provided by a machine tool or manually, to cause an additional relative motion between the

tool and workpiece, which, when added to the primary motion,

leads to repeated or continuous chip removal and the creation of a machined surface with the desired’geometric charac-

teristics. This motion may proceed by steps or continuously; in either case it usually absorbs a small proportion of the total

power required to perform a machining operation.

In certain machining operations, for example screw tapping and broaching, a feed motion as defined above is not required, the creation of the desired machined surface being achieved by the provision of an array of cutting edges which are arranged to

approach the workpiece in an ordered manner. In such cases, the feed motion is defined as the motion which an imaginary single cutting edge would have to be given by the machine tool to produce the same result as the array of cutting edges with which the tool is actually provided.

3.6.2.1 direction of feed motion (figures 8 to 1 I) : The direction of instantaneous feed motion of the selected point on the cutting edge relative to the workpiece.

3.6.2.2 feed speed vf (figures 8 to 11) : The instantaneous velocity of the feed motion of the selected point on the cutting edge relative to the workpiece.

When the feed is intermittent, for example in the case of a pianing operation, the feed speed is not defined.

3:‘.3 resultant cutting motion : The motion resulting from simultaneous primary motion and feed motion.

3.6.3.1 resultant cutting direction (figures 8, 9 and II) : The direction of instantaneous resultant cutting motion of the selected point on the cutting edge relative to the workpiece.

3.6.3.2 resultant cutting speed v, (figures 8, 9 and 11) : The instantaneous velocity of the resultant cutting motion of the selected point on the cutting edge relative to the workpiece.

3.6.4 feed motion angle cp (figures 8 to II) : The angle between the directions of simultaneous feed motion and primary motion. It is therefore measured in the working plane P,, (4.2.2).

In certain machining operations such as in planing, shaping and broaching this angle cannot be defined.

3.6.5 resultant cutting speed angle q (figures 8, 9 and II) : The angle between the direction of primary motion and the resultant cutting direction. It is therefore measured in the working plane P,, (4.2.2).

4 Reference systems

Reference systems of planes are necessary for defining and

specifying the angles of a cutting tool. One system (the tool-in-

hand system) is needed for defining the geometry of the tool

for its manufacture and measurement. A second system (the

tool-in-use system) is needed for specifying the geometry of

the cutting tool when it is performing a cutting operation.

NOTE -- A third reference system of planes (called the machine

reference system) is required to define the orientation of a cutting tool

with respect to the machine tool. This third reference system is defined

in IS0 3002/2.

The planes used in the first system. are termed tool-in-hand

planes, their titles, with two exceptions (4.12 and 4.1.5) each

include the word “tool”. The planes used in the second system

are termed tool-in-use planes; their titles, with one exception

(4.2.5). all include the word “working”.

Since angles and other geometric features vary from point to

point along the cutting edge of a tool, it is necessary to locate the reference system at whatever point one desires to be able to

define the tool geometry. Each plane is therefore defined, with respect to a selected point on the cutting edge. The title of the

plane may include an indication of whether the selected point is

located on the major or minor cutting edge: for example, at a selected point on the major cutting edge, there is the tool cutting edge plane (4.1.4) and at a selected point on the minor cut-

ting edge, the corresponding plane is termed the tool minor

cutting edge plane.

Each plane is provided with a symbol consisting of P with a suf-

fix indicating the plane’s identity (for example P,, the tool cut-

ting edge plane).

For the planes defined below the selected point on the cutting edge is considered to be located on the major cutting edge.

When it is necessary to distinguish clearly a plane passing

through a selected point on the minor cutting edge, the ap-

propriate symbol bears a prime (for example P,’ , the tool minor cutting edge plane).

When the cutting edge, face or flank is curved, the tangents or tangential planes through the selected point should be used in the reference systems of planes.

The symbol used for a plane in the tool-in-use system bears the additional suffix e, for “effective” (for example P,,, the working

cutting edge plane) to distinguish it from the corresponding

toolLin_hand plane (for example P,, the tool cutting edge plane).

4.1 Tool-in-hand system (figure 12)

4.1.1 tool reference plane P, (figures 12 to 17) : A plane

through the selected point on the cutting edge, so chosen as to be either parallel or perpendicular to a plane or axis of the tool convenient for locating or orienting the tool for its manufacture, sharpening and measurement.

The plane must be chosen and defined for each individual type

of cutting teal so that it meets the conditions prescribed above

and is generally oriented perpendicular to the assumed direc-

tion of primary motion.

For ordinary lathe, planer and shaper tools it is a plane parallel

to the base of the tool. For a vertical shank or tangential tool or

for a horizontal shank planer tool it is a plane perpendicular to the tool axis. For a side and face milling cutter, for drills and

screwing taps it is a plane containing the tool axis.

4.1.2 assumed working plane P, (figures 12 to 17) : A plane

through the selected point on the cutting edge and perpen-

dicular to the tool reference plane P, and so chosen as to be

either parallel or perpendicular to a plane or an axis of the tool convenient for locating or orienting the tool for its manufac-

ture, sharpening and measurement.

The plane must be chosen and defined for each individual type of cutting tool so that it meets the conditions prescribed above

and is generally oriented parallel to the assumed direction of

feed motion.

For ordinary lathe tools and planer tools it is a plane perpendicular to the tool axis. For drills, broaches, facing tools,

parting-off and cutting-off lathe tbols it is a plane parallel to the

tool axis. For milling cutters it is a plane perpendicular to the

tool axis.

4.1.3 tool back plane P, (figures 12 to 17) : A plane through

the selected point on the cutting edge and perpendicular both to the tool reference plane P, and to the assumed working

plane P,.

4.1.4 tool cutting edge plane P, (figures 12 to 17) : A plane tangential to the cutting edge at the selected point and perpendicular to the tool reference plane P,.

4.1.6 cutting edge normal plane P, (figures 12 to 17) : A

plane perpendicular to tl-@ cutting edge at the selected point on the cutting edge.

4.1.6 tool orthogonal plane P, (figures 12 to 17) : A plane


dicular both to the tool reference plane P, and to the tool cut-

ting edge plane P,.

4.1.7 tool face orthogonal plane P, (figure 13) : A plane

through the selected point on the cutting edge and perpendicular both to the face A, and to the tool reference plane P,.

4.1.8 tool flank orthogonal plane P, (figure 13) : A plane


dicular both to the flank A, and to the tool reference plane P,.

5 Tool and working angles 5.1 Tool angles

The angles are necessary for the determination of the geometrical position of the tool cutting edge, the face and the flank.

The tool angles are defined with the aid of the tool-in-hand reference system of planes (4.1).

One set of angles is needed for defining the angles of the tool as an entity in itself, that is, for the tool-in-hand; these angles are designated tool angles and, with one exception (5.1.3.11, have the prefix “tool” in their titles. These angles are necessary for manufacturing, sharpening and measuring the tool.

5.1.1 Orientation of cutting edge

5.1.1.1 tool cutting edge angle K, (figures 24, 26, 27 and 28) : The angle between the tool cutting edge plane P, and the assumed working plane Pr measured in the tool reference plane P,.

A second set of angles is needed for defining the angles which affect the action of the tool in the cutting process, that is for the tool-in-use; these angles are designated working angles and, with one exception 15.2.3.1). have the prefix “working” in their title.

6.1.1.2 tool approach angle; tool lead angle /USA/ vr (figures 24,26,27 and 281 : The angle between the tool cutting edge plane P, and the tool back plane P, measured in the tool reference plane P,.

Since tool and working angles vary from point to point along the cutting edge, the detinitions of the angles given below refer always to the angles at the selected point.

u/, is defined only for the major cutting edge. Thus at any selected point on the major cutting edge the sum of vr and K, is always 9o”.

When the cutting edge, face or flank is curved the tangents or tangential planes through the selected point are used in the reference systems of planes used to define the angles.

5.1.1.3 tool cutting edge inclination I, (figures 24, 27 and .28) : The angle between the cutting edge and the tool reference plane P, measured in the tool cutting edge plane P,.

Each angle is specified, where appropriate, with reference to a particular cutting edge on the tool, depending upon the lo- cation of the selected point on the cutting edge. The title of the angle may include an indication of whether the selected point is located on the major or minor cutting edge (for example, at a selected point on the major cutting edge, there is the tool normal rake and at a selected point on the minor cutting edge the corresponding angle is termed the tool minor cutting edge normal rake).

5.1.1.4 tool included angle cr (figures 24, 26, 27 and 28) : The angle between the tool cutting edge plane P,, and the tool minor cutting edge plane P,’ measured in the tool reference plane P,.

Thus, K, + q + K,’ = l&o0

5.1.2 Orientation of face

Each angle is provided with a symbol consisting of a Greek letter with a suffix, the suffix indicating the plane in which the angle is measured (for example Y,.,, the tool normal rake).

5.1.2.1 tool normal rake yn (figures 24, 27 and 281 : The angle between the face A,, and the tool reference plane P, mea&red in the cutting edge normal plane P,.

For the angles defined below the selected point on the cutting edge is considered to be located on the major cutting edge. When it is n ecessary to distinguish clearly angles defined with respect to a selected point on the minor cutting’edge, the appropriate symbols bear a prim0 (for example yn’ , the tool minor cutting edge normal rake).

5.1.2.2 tool side rake yr (figures 24, 27 and 28) : The angle between the face A,, and the tool reference plane P, measured in the assumed working plane P,.

The symbol used for a working angle bears the additional suffix e for “effective” (for example yne, the working normal rake) to distinguish it from the corresponding tool angle (for example yn, the tool normal rake).

5.1.2.3 tool back rake y,, (figures 24,27 and 28) : The angle between the face A,, and the tool reference plane P, measured in the tool back plane P,.

When the face or flank is composed of e number of surfaces inclined to one another, these surfaces are numbered con- secutively starting from the cutting edge. The number of the land is used as an additional suffix to the appropriate symbols to associate the rake or clearance angle with its particular Iand (for example ynl; yn2; Ynl’ ; yd’,; a,~; ad; 11,~’ ; ah’ 1.

5.1.2.4 tool orthogonal rake y0 (figures 24,27 and 28) : The angle between the face A, and the tool reference plane P, measured in the tool orthogonal plane P,.

5.1.2.5 tool geometrical rake yg (figure 251 : The angle between the face A, and the tool reference plane P, measured in the tool face orthogonal plane P,. It is the maximum angle be tween the face A,, and the tool reference plane P,.

When the face or flank has only one surface the suffixes 1, 2, etc. are not used.

m sign conventions of the various angles are given in 5.3.

5.1.2.6 tool face orthogonal plane orientation angle 6, (figure 25) : The angle between the assumed working plane P, and the tool face orthogonal plane P, measured in the tool reference plane P,.

5.1.4.6 tool flank orthogonal plane orientation angle 0,

(figure 25) : The angle between the assumed working plane P,

and the tool flank orthogonal plane P, measured in the tool

reference plane P,.

5.1.5 Relationship between the tool angles

The sum of the tool clearance, tool wedge angle and the tool

rake measured in any one of the following tool-in-hand planes - cutting edge normal plane, tool back plane, tool orthogonal

plane or assumed working plane - is equal to 90°.

a, + /3” + y” = 9o”

ap + BP + yp = 80°

a, + & + y. = 80°

af + bf + yf = 80°

In practice, the tool rake, tool clearance and tool cutting edge

inclination are usually acute angles.

5.3 Sign convention for angles

The sign convention for tool cutting edge orientation angles is defined with respect to planes and directions of motion defined

at a selected point on the cutting edge located at a corner

which is assumed to be sharp.

When a tool has more than one corner (for example, a cutting off tool, certain broaches, slot milling cutters or slotting tools

used in sharpening or planing) the angles of the cutting edges

and. their sign must be defined in relation to the particular cor-

ner under consideration. At each corner there is a set of major and minor cutting edge angles and major and minor cutting

edge inclinations. Each set of angles completely defines the cutting edge geometry at that particular corner.

When a cutting edge has no corner (for example, a slab milling

cutter) then one end of the major cutting edge is taken as a

reference. In such cases the .reference end is that from which the rotation of the tool relative to the workpiece is seen to be

clockwise.

In the case of a Vee-shaped threading tool, the point of

intersection of the projection of the straight portions of the cutting edge can be regarded as the selected point at a sharp cor-

ner and the orientations of the straight portions of the cutting

edge defined with respect to that point.

The sign convention for angles which defines the orientation of

the face and flank is defined with respect to planes and direc-

tions of motion at a selected point on the cutting edge, located

at any point where the face and flank orientation is required to

be specified.

5.3.1 Tool angle convention

5.3.1.1 The tool cutting edge angle K, (see 5.1.1.1) is

always positive. The appropriate angle of the two possible

angles defined by the intersecting planes is the one which is

measured from the portion of Pr containing the assumed direc-

tion of feed motion towards that part of the major cutting edge

away from the tool corner being considered or away from the reference end of the major cutting edge in the case of a slab

milling cutter (see 5.3).

The tool minor cutting edge ahgle K’ r (see 5.1.1.1) is usually acute and its sign is determined from the relationship

K, + cr + K’ r = 180”. where e, is always Positive and measured within the boundaries of the cutting part.

IS : 11522 (Part l)-1986 IS0 3002/1-l 982

5.3.1.2 The tool approach angle w, (see 5.1.1.2) is

always acute and its sign is determined from the relationship

K, + I)/, = 90’.

5.3.1.3 The tool cutting edge inclination 1, (see 5.1.1.3) is

always acute. The angle is positive if the cutting edge, when

viewed in a direction away from the selected point at the tool

corner being considered, lies on the opposite side of the tool

reference plane P: from the assumed direction of priman/ motion.

5.3.1.4 Tool rake ahgles Y”, Yf, y,,, yO, y, (see 5.1.2.1 to 5.1.2.5) are always acute. The angle is positive if, when looking

across the face from the selected point and along the line of

intersection of the face and the plane of measurement, the

viewed line of intersection lies on the opposite side of the tool

reference plane P, from the assumed direction of primary motion.

5.3.1.5 Tool cleirance angles a,, at, ap, a,, ab (see 5.1.4.1 to 5.1.4.5) are always acute. The angle is positive if, when looking across the flank from the selected point and along the line

of intersection of the flank and the plane of measurement, the

viewed line of intersection lies on the opposite side of the tool

cutting edge plane P, from the assumed direction of feed motion.

Tool minor cutting edge clearance angles a,‘, af’, ap’, a,‘, ab’ (see beginning of clause 5J are always acute. The angle is

positive if, when looking across the minor flank from the

selected point and along the line of intersection of the minor

flank and the plane of measurement, the viewed line of in-

tersection lies on the same side of the tool minor cutting edge

plane P,’ as the line of intersection of the face and the plane of

measurement.

5.3.2 Working angle convention

The same physical bases and directions of measurement which

define the sign convention for tool angles must be maintained

to define the convention for working angles, in conjunction _

with the tool-in-use reference system of planes and the direc-

tions of primary and feed motions.

7 Chip breaker

Repeat of the definition given in 3.3.1.2:

with an increase in the distance of the point of measurement away from the minor cutting edge.

chip breaker: A n&ification of the face A,, to control or

break the chip, consisting of either an integral groove or an in-

tegral or attached obstruction.

7.1 defined point on the chip breaker (figures 33,34,35) : The point of intersection of the cutting edge normal plane P, (through the selected point on the major cutting edge) with the

top edge of an attached chip breaker or with the rear edge of an

integral chip breaker.

7.6 chip breaker wedge angle era (figures 33, 34) : The

acute angle between the face A, of the tool and the active face

of’the chip breaker measured in a plane perpendicular to the

top edge of the chip breaker and through the defined point on

the chip breaker. Where the chip breaker face is curved the

wedge angle is measured between the tangent to this face at the same defined point and the face of the tool. This angle is

usually defined only for obstruction type chip breakers.

7.7 chip breaker radius rR (figure 34) : The nominal radius

7.2 active face of the chip breaker (figures 33, 34, 35) : That surface of the chip breaker which is intended to come into

contact with the chip.

of the curved surface of an obstruction type chip breaker

measured in a plane perpendicular to the top edge of the chip

breaker and through the defined point on the chip breaker.

7.3 chip breaker distance I,, (figures 33, 34, 3511) : The

distance from the selected point on the major cutting edge to

the projection of the defined point on the chip breaker on the

face A,, measured in the cutting edge normal plane P,.

7.4 chip breaker height ha (figures 33, 34, 3511) : The distance from the face A,, to the defined point on the chip

breaker measured in a direction perpendicular to the face. This

distance is usually defined only for obstruction type chip breakers.

7.5 chip breaker angle ~a,, (figures 33, 34, 35)‘) : The acute

angle between the major cutting edge and the projection on the

face A, of the top or rear edge of the chip breaker measured in

the face. Where the major cutting edge or the top or rear edge

of the chip breaker are curved, the angle is measured between

the tangent to the cuttingsdge at the selected point and the tangent of the projection of the top or rear edge of the chip

breaker at the projection of the defined point.

The angle is positive if the distance between the major cutting

edge and the top or rear edge of the chip breaker decreases

7.8 chip breaker groove radius ran (figure 35) : The

nominal radius of a groove type chip breaker measured in the

cutting edge normal plane P,.

7.6 chip breaker groove depth ca, (figure 3511) : The max-

imum depth of the groove type chip breaker measured from the

plane of the face A,, and in the cutting edge normal plane P,.

7.10 chip breaker land width da, (figure 3511) : The

distance from the selected point on the major cutting edge to the nearest point of intersection of the groove type chip breaker

and the face A, measured in the cutting edge normal plane P,.

7.11 chip breaker distance from corner of tool dBv

(figures 33 and 3511) : The distance measured in the plane of

the face A, and in a direction parallel with the tool cutting edge

plane P,, between a plane tangential to the end of the chip

breaker and perpendicular both to the tool reference plane P,

and to the tool cutting edge plane P, and a plane tangential to

the tool corner and perpendicular both to the tool reference

plane P,, and to the tool cutting edge plane P,.

1) When thk tool has more than one face, the face from which or in which the measurement is made must be specified.
