225HEIDENHAIN TNC 426 B, TNC 430
ROTATION (Cycle 10)
The TNC can rotate the coordinate system about the active datum
in the working plane within a program.
Effect
The ROTATION cycle becomes effective as soon as it is defined in
the program. It is also effective in the Positioning with MDI mode of
operation. The active rotation angle is shown in the additional
status display.
Reference axis for the rotation angle:
■
X/Y plane X axis
■
Y/Z plane Y axis
■
Z/X plane Spindle axis
Before programming, note the following:
An active radius compensation is canceled by defining
Cycle 10 and must therefore be reprogrammed, if
necessary.
After defining Cycle 10, you must move both axes of the
working plane to activate rotation for all axes.
ú
Rotation: Enter the rotation angle in degrees (°). Input
range: –360° to +360° (absolute or incremental).
Example NC blocks:
81 CYCL DEF 10.0 ROTATION
82 CYCL DEF 10.1 ROT+12.357
Cancellation
Program the ROTATION cycle once again with a rotation angle of 0°.
