The more you increase the value of
BT, the smaller
will be the effect of an extended program duration
through
M101. Please note that this will delay the
automatic tool change!
To calculate a suitable initial value for
BT, use the
following formula: BT = 10 : average machining
time of an NC block in seconds . Round up to the
next odd integer. If the calculated result is greater
than 100, use the maximum input value of 100.
If you want to reset the current age of a tool (e.g.
after changing the indexable inserts), enter the value
0 in the CUR_TIME column.
The M101 function is not available for turning tools
and in turning mode.
Prerequisites for NC blocks with surface-normal vectors and
3-D compensation
The active radius (
R + DR) of the replacement tool must not differ
from the radius of the original tool. You can enter the delta values
(
DR) either in the tool table or in the TOOL CALL block. If there
are any deviations, the TNC displays an error message and does
not replace the tool. You can suppress this message with the
M function
M107, and reactivate it with M108.See also: Three-
dimensional tool compensation (software option 2).
