I so insert nomenclature training

welcome to the iso carbide insert

nomenclature worksheet and we're going

to instruct you on this right now this

worksheet is partially developed from

the kena metal catalog 2090 micro

machining tooling the iskar catalog

complete mate machining solutions 2006

and the Kyocera cutting tools catalog

2007-2008 those are the references that

we use plus we used a couple other

catalogs not all of this information

will be found in a single catalog again

we combine several catalogs to give you

as much information as possible the ISO

standard for inserts most people who

work on the machines will understand a

see CMT they know it's may be needed

agree insert but they don't know what

all these letters and numbers designate

about the insert and we're going to go

over this and we're going to show you

exactly what they are and how you're

going to use this sheet and the ISO tool

holder nomenclature worksheet to match

your tools with your inserts and we'll

go over why in just a little bit the

first position as we see as a see if we

look down the list our first letter is a

see it tells us that this holder is an

80-degree diamond that's the first

position holds an 80 degree diamond

insert now if you have a V BMT insert

you're going to look down a V is 35

degree or if it's DC MT D is a 55 degree

and there's going to be some other

inserts in here we may not even use but

it's used on several other machines it's

an 85 degree 82 degree 55 degree

parallelogram a rectangle diamond

octagonal you'll you'll notice all these

inserts are listed here our standards

5535 80 degree are covered within here

as well and they're highlighted the

second position is the relief angle okay

we have a C so we go up the list it's

highlighted it tells us that it's a 7

degree packet now 7 degree clearance

angle or a relief angle it's from the

cutting tip down to the base of the

insert or the bottom of the insert so

there's a 7 degree relief all the way

around the insert this is very important

because your tool holder must also have

the matching degree angle on it in the

pocket okay the insert is a 7 degree

so our holder has to have a 7 degree

pocket this information was developed

because of one of our customers while

doing a training session had an operator

change an insert and install a new

insert and then have it fall apart he

couldn't hold size couldn't hold length

and it took a while to figure out that

what had happened was he had pulled out

an insert which was a CCM t as listed

here but not paying attention he pulled

out an insert from another holder and it

turned out that that insert was a CP as

actually was a CP GT the P if we look in

the second position the P is an 11

degree so he put an 11 degree insert

into a 7 degree pocket which means that

only the bottom of the insert the very

base would sit in the pocket so even

with a set screw when tightened down

we're still moving and rocking around

because there was no support for it

so once we figure that out we developed

a sheet so operators and setup men can

actually reference insert verses holders

to be sure they have the correct one ok

so anyways with this one here we know we

have an 80 degree diamond because of our

first letter C our second letter C tells

us it's a 7 degree pocket the M tells us

our tolerance on the manufacturing in

that insert alright the tolerance of M

we look down the list is two to four

thousandths on our inscribed circle and

five thousandths on the thickness okay

dad's going to come into play in just a

little bit here

okay so rope here we go to insert type

which is the T so we look up at the T

and it's a partial cylinder why

time chip break countersink okay it's

the center screw style because it has a

countersink one time chip break which

means it's a single sided insert if you

were using CMG where this would actually

be a G in here you would look it up

cylindrical two times chip break which

means it's a two-sided two-sided insert

both with chip breakers on both sides

for our for this insert here we're using

a t so the T tells it's partial cylinder

one time chip break and it has a

countersink which is a Center screw now

the next position I have a - there's

nothing there that's just a placeholder

the number-5 okay right here part of our

iso standards is the insert size or the

inscribed circle which we already listed

before part of the tolerances on the

inscribed circle on an M it's two to

four thousandths this tells us it's a 3

Series insert the 3 Series says it's 3/8

okay so the inscribed circle or the

circle that runs around the center

section of the insert if you're looking

at the top and goes from edge to edge is

3/8 if we were running a two sides

insert which is a smaller one you'll

notice the two says it's a quarter inch

inscribed circle the sixth position

insert thickness it's 2.5 we look at the

2.5 and it is 5 30 seconds that's the

actual thickness of the insert or the

depth of that pocket that that insert

sits in to get it back to Center or near

Center number 7 corner radius now this

says it's a point five look down the

list of point five point five tells me

it's an eight thousand OHS radius now

one thing you got to remember on these

corner radiuses like any of these

inserts you know their menu for int just

like we do and they are manufactured to

print but there's a tolerance on them

now I don't have listed what the

tolerance of tolerances are on these

inserts but they on these bigger ones

they do vary like

on an 8000 without and a half until you

get down to the zeros which would be

like a 30 to 50 or you go down to the X

zeroes

all right the X zero is only a thousand

1/2 nose radius they will be within five

tenths the same thing with the zero they

are usually within five tenths either

side of four and it's not until you get

to the larger inserts that they kind of

have more tolerance on them and they'll

actually kind of go up or down by a sour

so so looking at this insert that we

have listed at least right here for

right now up to number seven we know

that number one is a sea

so it's an 80-degree we know that it's a

7 degree relief angle we know it's

tolerances at two to four thousands on

the inscribed circle five thousandths on

the thickness we know that it's a

partial cylinder one-time chip breaker

with a countersink because it's a center

screw we know that the insert size it's

a 3/8 inscribed circle we know that the

two-and-a-half tells us it's a 5/32 deep

or with on the insert we know station

seven that it's a point five that it's

an eight nose radius up to this point

it's pretty easy and all the

manufacturers are going to follow that

same format all rights all iso standard

the next positions from here our iso

standard but they're not used because so

much because they're optional they're

optional information and you're going to

notice that it changes a little bit

between manufacturer in this case we

have number eight is listed through iso

as a writer left-hand of the insert okay

now you're going to see in this note up

here most others use number eight as the

edge prep and nine and ten as the chip

form and right or left-hand okay

kena metal kind of flip there's around a

little bit they're not using number

eight but in nine and ten they're using

our cutting edge condition or chip

control features which the others use as

in number eight

so kena metal kind of skips ate and then

goes to 9 where the other manufacturers

use 8 and skip 9 so in the skin of metal

insert it's an LF chip breaker so this

is the cutting edge condition or chip

control features we go to the LF L F is

light finishing you're gonna notice in

the iskar catalog or the Kyocera catalog

they're going to tell you whether it's a

honed edge or a ground edge and what

type of chip breaker they have on them

and stuff like that and that's going to

be some of these other numbers that

you're going to see so that's 9 and 10

we get to 11 12 and 13

it's the teal and with again this is

optional you will only find it on some

of the inserts not all of them

oh four is gonna equal four thousandths

oh it is going to equal an eight

thousands no also have the metric

numbers there as well four millimeters

after 11 12 and 13 you have 14 and 15

which is a teal and angle now again this

is optional if the symbol is going to be

10 for a 10 degree 15 for a 15 degree

all the way up to 30 for a 30 degree and

then the 16th position is again it's

going to be optional you don't find it

on all the inserts MT is multi tip M as

mini tip d is two-sided mini tip again

positions 8 through 16 are only

partially partially used by the

manufacturers normally it's just 8 9 10

that are used the rest again are

optional for other style of inserts so

we know that this insert here again is

an 80 degrees 7 degree angle or

clearance angle we know it's a and M

which is 2 to 4 thousand a $5 ensign

thickness we know that the T tells us

that it's a partial cylinder one-time

chip break we know that it's a 3/8

inscribed circle insert we know that

that it's a 5/32 wide we know that it's

got an 8 nose radius and it's using a

nun for Kenna metal and LF chip breaker

or light finishing that's what's

recommended and Swiss machine you know

it's used as rougher and semi rougher

and finisher
