5. Tool life count:
When the count result is for the used life value being more than or equal to the setting value
of the life data, the next tool group number selects the standby tool in the commanded selection
tool group and the new selected tool will be counted, the count will be continuously executed and
the system alarms to output to PLC when all tool life in the tool groups reaches and there is no
standby tools. Executing the counting in MDI mode is determined by No.002 Bit3 (MDITL).
002
MDITL
MDITL
=
0 Tool life management is invalid in MDI mode.
MDITL
=
1 Tool life management is valid in MDI mode.
The tool life count has two methods including time and number of times.
1). Time count
Use the time (minute) to count the tool life in cutting feed mode(such as G01, G02, G03,
G32, G33, G34 and so on), and do not count it in G00, G04, single block stop, machine lock,
auxiliary lock, dry run and so on.
2). Number of times count
There are two methods about the number of times count which is determined by No.002 Bit2
(LIFC).
002
LIFC
LIFC=0 Tool life management count mode 1
Execute the tool select (Txx99) to change the tool number, execute the count in the cutting
feed mode (except for machine lock, auxiliary lock, dry run state). The count is not executed
when the tool number is changed and the system is not in the cutting feed mode.
Application example:
Use 3 times in 01 tool group use once in 01 tool group
LIFC
=
1 Tool life management count 2
The tool group adds when the machining program runs to M30(M99), when the system
resets halfway, the number of time does not add, the count is not executed in machine lock,
auxiliary lock and dry run mode.
