Tool change
Automatic tool change
Refer to your machine manual.
The tool change function can vary depending on the
individual machine tool.
If your machine tool has automatic tool changing capability, the
program run is not interrupted. When the control reaches a tool call
with
TOOL CALL
, it replaces the inserted tool by another from the
tool magazine.
Automatic tool change if the tool life expires: M101
Refer to your machine manual.
The function of
M101
can vary depending on the
individual machine tool.
When the specified tool life has expired, the control can
automatically insert a replacement tool and continue machining with
it. Activate the miscellaneous function
M101
for this.
M101
is reset
with
M102.
Enter the respective tool life after which machining is to be
continued with a replacement tool in the
TIME2
column of the tool
table. In the
CUR_TIME
column the control enters the current tool
life.
If the current tool life is higher than the value entered in the
TIME2
column, a replacement tool will be inserted at the next possible
point in the program no later than one minute after expiration of
the tool life. The change is made only after the NC block has been
completed.
NOTICE
Danger of collision!
During an automatic tool change with
M101
, the control always
retracts the tool in the tool axis first. There is danger of collision
when retracting tools for machining undercuts, such as side
milling cutters or T-slot milling cutters!
Use
M101
only for machining operations without undercuts
Deactivate the tool change with
M102
After the tool change the control positions the tool according to
the following logic, unless otherwise specified by the machine tool
builder:
If the target position in the tool axis is below the current position,
the tool axis is positioned last
If the target position in the tool axis is above the current position,
the tool axis is positioned first
