430 Programming: Special Functions
11.5 Global Program Settings (software option)
Basic rotation
The basic rotation function enables you to compensate a workpiece
misalignment. The effect corresponds to the basic rotation function
that you can define in the manual mode with the probing functions.
You can change the basic rotation value in the form, but the TNC does
not write it back into the basic rotation menu or the preset table.
Please also note that when a preset is activated by an NC program
(e.g. via Cycle 247), the TNC activates the basic rotation entered in the
corresponding row of the preset table (ROT column of the preset table).
In this case the TNC replaces the value entered in the form with the
value from the preset table. If the value 0 is entered in the preset table,
then no basic rotation is active once such a row has been activated.
If you press the SET STANDARD VALUES soft key, the TNC restores
the basic rotation assigned to the active preset.
Remember that you may have to return to the contour
after activation of this function. The TNC then
automatically calls the return-to-contour menu after the
form is closed (see "Returning to the contour" on page
657).
Please note that probing cycles with which you measure
and write a basic rotation during program run overwrite the
value defined by you in the fillable form.
