Use the TRANS MIRROR function to mirror contours or positions
about one or more axes. The TRANS MIRROR RESET function
allows you to reset the mirroring. The NC functions serve as an
alternative to Cycle 8 MIRRORING.
With the TRANS SCALE function, you can scale contours or
positions and thus enlarge or reduce these uniformly. This
enables you to program shrinkage and oversize allowances, for
example. Use the TRANS SCALE RESET function to reset the
scaling. The NC functions serve as an alternative to Cycle 11
SCALING FACTOR.
Using the SYNTAX soft key, you can enclose path information in
quotation marks in order to use any special characters as part of
the path, e.g. /. The control provides the SYNTAX soft key with the
following NC functions:
Cycle 12 PGM CALL (ISO: G39)
Further information: User's Manual for Programming of
Machining Cycles
CALL PGM (ISO: %)
FN 16: F-PRINT (ISO: D16)
FN 26: TABOPEN (ISO: D26)
The FN 18: SYSREAD (ISO: D18) functions have been extended:
FN 18: SYSREAD (D18) ID10: Read program information
NR8: Unit of measure of the calling NC program
NR9: Number of the miscellaneous function
The function is available only within M function macros.
FN 18: SYSREAD (D18) ID210: Read active coordinate
transformations
NR11: Coordinate system for manual movements
FN 18: SYSREAD (D18) ID295: Read data of the machine
kinematics
NR5: Type of use of an axis within the kinematics
FN 18: SYSREAD (D18) ID310: Read geometrical behavior
NR126: State of the miscellaneous function M126
The control includes the sample tables WMAT.tab, TMAT.tab and
EXAMPLE.cutd for automatic cutting data calculation.
In CAD-Viewer, you can choose the YZ and ZX working planes
for milling. You can choose the desired working plane from a
selection menu.
Within the file manager, the control hides system files, as well as
files and folders whose name begins with a period. If necessary,
you can display the files with the SHOW FILES soft key.
