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 PROGRAM + 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
