3.2.2.30 G88 Basic rotation
Rotation of the systems S1 − S31 in the XY plane.
G88 C X Y
C Basic rotation angle in degrees.
X, Y Determination of the basic rotation angle from Delta X and Delta Y
The basic rotation is used to define the position of a workpiece (S1 ... S31)
relative to the machine workspace (S0). The rotation is effective for S1 ... S31
together about the same angle in the XY plane. In the reference workpiece
coordinate system S0, the rotation has no effect, however, the rotation can
be defined there, vertically in S0. It only becomes active when changing over
to S1 ... S31.
When the rotation is activated, the actual positions of the X, Y and C axis are
adjusted to the new position; a compensating movement does not take
place.
The specification of the angle is an absolute specification.
The rotation is deactivated by programming the G88 without parameters or
by the specification of angle 0
°
.
The function has a modal effect and remains active until the control is
deactivated or reset.

N3 G88 C30 With block 3, a rotation of the XY plane is activated for all systems
S1 ... S31 about 30 degrees, relative to the unrotated S0. The
rotation takes effect immediately, since it was activated in S1
vertically.
