Use the following general cycle machine data to set the access level as of which the
"Calibrate probe" softkey is displayed. This requires that the automatic tool measurement is
enabled using the setting data SD54782 (bit 2 = 1).

Measuring behind the turning center

Working with two toolholders
It is possible to work on a single turning machine with two toolholders, both of which are
mounted on an X axis. The toolholders may be revolvers, multifix, or a combination of both.
Since both tool adapters are mounted on the same axis, it is only ever possible to work with
one tool at a time. The workpiece is located between the two tool adapters.
All tools have the same reference point (on toolholder 1) irrespective of which toolholder they
are on. For this reason, the tool lengths of the second toolholder are always longer than the
tools on the first toolholder. The main machining is performed in the negative X axis
direction.
Note
If there are a large number of old G code programs that were programmed without mirroring
of the X axis, you should consider setting mirroring for G code programs.
If the corresponding mode of operation of the second toolholder (with mirroring of the X axis)
is also to be used for G code programs, then additional settings must be configured.
To automatically activate the mirroring when loading tools to the second toolholder, the
following T replacement must be set:
MD10717 $MN_T_NO_FCT_CYCLE_NAME="F_T_REV2"
