HEIDENHAIN | TNC 640 | Conversational Programming User's Manual | 10/2017
The functions in the software option VSC (option 136) have been
expanded and adapted for improved operation, see "Camera-
based monitoring of the setup situation VSC (option 136)",
page 789
New machine parameter for recreating
M7
and
M8
, see
"Machine-specific user parameters", page 882
New machine parameter for defining the minimum feed rate
in turning cycles, see "Machine-specific user parameters",
page 882
New machine parameter for deactivating parallel axis
programming, see "Working with the parallel axes U, V and W",
page 552
The function
STRLEN
checks whether a string parameter has
been defined, see "Finding the length of a string parameter",
page 462
The function
SYSSTR
enables the NC software version to be
read out, see "Reading system data", page 459
The function
FN 38: SEND
can now be programmed without a
code number
Undefined Q parameters can now be transferred with the
function
FN 0
For jumps with
FN 9
, QS parameters and texts are permitted as
conditions, see "Programming if-then decisions", page 387
Cylindrical workpiece blanks can now also be defined with
a diameter instead of a radius, see "Defining the blank: BLK
FORM", page 162
Programming of
TCPM AXIS SPAT
is possible with active Cycle 8
and Cycle 10
It is now possible to program up to 6 axes in a straight line
block, see "Three-dimensional movement", page 285
The transitional elements
RND
and
CHF
can now also be
executed between 3-D contours, i.e. with straight line blocks
with three programmed coordinates or a helix
The control now supports spatial arcs, i.e. circles in 3 axes
vertical to the working plane, see "Circular path C around circle
center CC", page 303
Active kinematics is displayed in the 3D-ROT menu, see
"Activating manual tilting:", page 786
In operating modes
Program run, single block
and
Program
run, full sequence
the screen layout
P SECTS
can be
specified, see "Structuring programs", page 212
In operating modes
Program Run Full Sequence
,
Program Run
Single Block
and
Positioning w/ Manual Data Input
, the font
size can be set to the same size as the
Programming
operating
mode, see "Machine-specific user parameters", page 882
The functions in the
Positioning w/ Manual Data Input
mode
were expanded and adapted for improved operation, see
"Positioning with Manual Data Input", page 797
Active kinematics is displayed in the operating mode
RETRACT
,
see "Retraction after a power interruption", page 830
In the
RETRACT
operating mode, feed-rate limitation can be
deactivated with the
CANCEL THE FEED RATE LIMITATION
soft
key, see "Retraction after a power interruption", page 830
