The tool life control data can be cleared by

ing the

command. If a command for P is

given in the same block as

one group only

will be erased. (P = 1 to 128)

In other words, by entering the command

. ..., it will be possible to erase only the

group specified by P.

Notes :

(i) All previously registered data will be

executing G 124 ;.

If command G 122 is entered without

executing G 124, the following will occur.

(a) If tool numbers have already been registered

previous data will be erased and replaced with
new data.

If H and D are omitted in the block

in which T exists,

T will change to unregistered

(* mark).

(b) If tool numbers are unregistered, new data
will be registered in simple form.

If H and D

are omitted in the block in which T exists, T

change to unregistered ( * mark) .

If L is

omitted, L9999 will be stored.

(ii) Settings are possible in which “registration

will start after canceling all previously registered
data if command

is executed” .

(iii) The H and D codes can be omitted when not

being used.

(iv) Tool life L will be modal between G 122 and

G 123 so these commands can be omitted when
setting to the same tool life.

(v) The

life classifications can be set by

IO . . . . Controlling by time (1 to 9999 minutes)

11 . . . .

Controlling by counts (1 to 9999 counts)

12 . . . .

Controlling by distance (1 to 9999 mm,

1 to 9999 feet)

13 . . . .

Controlling by the drilling count (1 to 9999
counts)

(vi) Each of the addresses T, H, D, L, P, I has the follow-
ing commendable range. Any other command values will
cause in an error.

128>0< I

(vii) Commands G122 and G123 can be used in indepen-
dent blocks.

Do not enter commands (such as a shift command)

other than tool information in the G 122 ; . . . G123 ;
section. (Alarm will occur if such a command is entered.)

(ix) Do not switch over the mode to execute a manual
MDI command while executing G 122 ;. (Alarm will occur
if this is attempted.)

( x ) If I is omitted, the life classification originally speci-

fied in that group will remain unchanged.

A cleared group will generally become in the “minutes”

state.

2.9.32.4 EXECUTION

OF TOOL LIFE CONTROL

(1) Commands with the part program

Tool life control can be performed with commands
from the part program by using the T and H
codes shown in the table below.

Table 2.31 Tool Life Control by Part Program

Tape Format

TIOOO1;

H999;

D999;

DO;

Meaning

Tool life control ON mode will be set with
the M06 command of “tool group number

10000. “

The tool will be mounted on the main shaft
with the M06 command and time and distance
count will normally start thereafter.

The H-NO registered on the tools will be
selected with the H999 command.

The D-NO registered on the tools will be
selected

the H999 command.

Cancel D

HO;

Cancel H

Returns to normal T command

The tool on which life control is being carried
out with the

command will be removed

from the main shaft and counting of time and
distance will end.

M30

Machining ends.

Notes :

1. The T code command of the numerical value

of “tool life group number + 10000” with TIOOO1
to T 10128 controls tool life and outputs the
T codes registered in that group.

2. The H and D codes of the

being selected

will be selected by commands H999 and D999
with the tool life control function.

(2) Tool life count

(a) One of the following can be selected with

parameter #6020 on the tool on which life count
is to be performed.

. Counting of a tool in the latest T command

group of the M06 command.

, Counting of a tool in the T command group

just prior to the M06 command.

(b) Tool life count will not be performed by time,

distance or counts when the “tool life count dis-
regard input” is in ON state.

The control will count every second in which the
tool is actually used in the section between

and

of the table in para. (1) and, in the cutting

mode.

Life count will be increased by each

time one minute is exceeded.

However, the

t i m e

for

single block stop, feed hold, fast

feed and dual operation will not be counted.
