In the NC program, the #n920(G) variable can be used to
interrogate the status of the shifts G920/G921, see "Reading the
current NC information", Page 468
In smart.Turn operating mode, the number of an M function
can now also be defined with a variable, see "Variable types",
Page 461
In smart.Turn operating mode, up to four contour groups are
supported, see "Contour group section", Page 64
In an NC program generated by the AWG submode, the tool
traverses to the tool change position after the parting working
step, see "Automatic working plan generation (AWG) submode",
Page 619
In a program generated by the AWG submode, machining is
now also possible with simplified geometry programming,
see "Automatic working plan generation (AWG) submode",
Page 619
The TURN PLUS function can now also be used in INCH mode
The CW parameter was changed into a query Reverse the tool
0: No 1: Yes, "Tool ext form"
The Q parameter in G99 is supported, see "Transformations of
contours G99", Page 490
The parameter DO ("Flow") was added to the G860 Contour
recess in ICP and G860 Contour recess, direct cycles, see "ICP
contour recessing unit", Page 96, see "Contour recessing
with direct contour input unit", Page 100
The Type of tool access parameter can now also be modified via
the machining parameters in the smart.Turn operating mode,
see "Tool selection and turret assignment list", Page 636
The function G154 Short path in C was introduced, see "Short
path in C G154", Page 393
The parameter O Flow was added to G741, see "Repeating
recessing cycle G741", Page 329
Parameter A of G845 has been enhanced with the input option
for pilot drilling in the reference point of the figure, see "Pocket
milling - roughing G845", Page 425, see "Pocket milling -
roughing G845 (Y axis)", Page 597
The input range was expanded for Boring depth in the G74
drilling cycle
With paraxial turning cycles, an error message is no longer
issued if machining is executed with the secondary cutting edge
of the tool
Machining parameters are displayed in millimeters or inches
according to the CfgUnitOfMeasure parameter (no. 201605).
