Coordinate Plane Rotation by Angle of Rotation 'P'
Coordinate plane rotation is used to adapt the coordinate system of the
workpiece to the coordinate system of the machine. The angle of rotation
P is assigned to the individual zero offsets G54 … G59, G50, G51 and the
adjustable general offset. Coordinate rotation is always active in the active
plane (for example G17).
With the adjustable zero offsets G54 …G59 and with the adjustable gen-
eral offset, the angle of rotation is entered as PHI in the zero offset table.
The angle of rotation is programmed using the address Pxxx with the
programmable zero offsets G50 and G51.
•
The total of all active rotational angles is subject to the same condi-
tions as with the zero offsets.
•
As a rule, the angle of rotation is not active until the next active NC
NC-block.
•
The angle of rotation is calculated in the controller as a modulo value
from 0° to 360°. This means that a programmed angle of, for example
540°, is calculated as 180°.
•
Coordinate rotation cannot be programmed with the programmable
workpiece zero point G52.
