New functions
New functions of software 688945-03, 68894x-01, 548328-05
and 54843x-01
In Organization operating mode, you can grant or restrict
access to the control by using the EXTERNAL ACCESS soft key,

see User's Manual

The pocket calculator can now be activated in each application
and also remains active after a change in operating modes.
With the GET CURRENT VALUE and CONFIRM VALUE soft keys,
numerical values can be fetched from the active input field and
transferred to the active input field, see User's Manual
Tool touch probes can be calibrated in the Setup menu,
see User's Manual
The workpiece datum can also be set in the Z axis direction with
a touch probe, see User's Manual
In Teach-in submode the RI and RK workpiece blank oversizes
have been introduced for finishing operations with the recess
turning cycles, see User's Manual
The RI and RK workpiece blank oversizes were introduced in
the finishing operations with the recess turning units and in the
G869 cycle, see "Recess turning cycle G869", Page 331
On machines with a B axis it is also possible to drill, bore, and
mill in oblique planes. In addition to this, the B axis enables
you to use tools even more flexibly during turning, see "B axis",
Page 655
The control provides numerous touch probe cycles for various
applications, see "Touch probe cycles", Page 519:
Calibrating a touch trigger probe
Measuring circles, circle segments, angle and position of the
C axis
Misalignment compensation
Single-point and double-point measurement
Finding a hole or stud
Datum setting in the Z or C axis
Automatic tool measurement
The new TURN PLUS function automatically generates NC
programs for turning and milling operations based on a
fixed machining sequence, see "The function TURN PLUS",
Page 618
G940 now provides a way to calculate the tool lengths in the
basic (definition) position of the B axis, see "Calculating variables
automatically G940", Page 444
For machining operations that require rechucking, you can
define a separation point on the contour description with G44,
see "Separation point G44", Page 268
G927 enables you to convert tool lengths to the reference
position of the tool (B axis = 0), see "Convert lengths G927",
Page 443
Recesses that were defined with G22 can now be machined
with the new Cycle G870 ICP Recessing, see "ICP recessing
unit", Page 104
