Tables and Overviews | Functions of the TNC 640 and the iTNC 530 compared
Function
PLANE function:
TABLE ROT/COORD ROT
Machine is configured for axis
angle
Programming an incremental
spatial angle according to PLANE
AXIAL
Programming an incremental
axis angle according to PLANE
SPATIAL if the machine is
configured for spatial angles
Programming of PLANE
functions with active Cycle 8
MIRROR IMAGE
Axis positioning on machines
with two rotary axes
e.g.
L A+0 B+0 C+0
or
L A+Q120 B+Q121 C+Q122
Special functions for cycle
programming:
FN 17
FN 18
Compensation of tool length in the
position display
HEIDENHAIN | TNC 640 | ISO Programming User's Manual | 10/2017
TNC 640
Effect:
The transformation types are
effective on all free rotary axes
The control does not always
position the free rotary axis
with TABLE ROT, but depending
on the current position, the
programmed spatial angle and
the machine kinematics
Default with missing selection:
COORD ROT is used
All PLANE functions can be
used
Error message is issued
Error message is issued
Mirroring has no influence on
tilting using AXIAL PLANE and
Cycle 19
Only possible after a tilting
function (error message if
without a tilting function)
Parameters that are not
defined are given the status
UNDEFINED; they are not given
the value 0
Function available
Values are always output in
metric form
Further details are different

metric form

The tool length entries L and DL
from the tool table are taken into
account in the position display,
from T block depending on the
machine parameter progTool-
CallDL(no. 124501)
iTNC 530
Effect
The transformation types are
only effective with a C rotary
axis
With TABLE ROT the control
always positions the rotary axis
Default with missing selection:
COORD ROT is used
Only PLANE AXIAL is executed
Incremental spatial angle is
interpreted as an absolute value
Incremental axis angle is
interpreted as an absolute value
Function is available with all
PLANE functions
Possible at any time if spatial
angles are used (machine
parameter setting)
The control assigns the value 0
to parameters that are not
defined
Function available
Values are output in the units of
the active NC program
Details are different
