ROTATION (Cycle 10)

Function

The coordinate system can be rotated about the active datum in the
working plane within a program.

Effect

The rotation takes effect as soon as it is defined in the program.
Cycle 10 ROTATION cancels radius compensation RR/RL.

Reference axis for the rotation angle:

„

X/Y plane X axis

„

Y/Z plane Y axis

„

Z/X plane Z axis

The active rotation angle is shown in the status display (ROT).

Definition of the plane of rotation

When the ROTATION cycle is activated for the first time, the plane of
rotation is perpendicular to the tool axis defined in the tool call block.

If later a TOOL CALL block with a different tool axis is executed, the
plane of rotation will not change.

Input

Enter the rotation angle in degrees (°).
Input range: –360° to +360° (absolute or incremental).

Effect on Q parameters

The plane of rotation influences Q parameter Q112:

„

X/Y plane Q112 = 2

„

Y/Z plane Q112 = 0

„

Z/X plane Q112 = 1

„

No plane defined Q112 = –1

Cancellation

A rotation is canceled by entering a rotation angle of 0°.
