Programmed Workpiece Zero Point 'G52'
A workpiece zero point can be programmed as the axis position for all
axes which are present using programmed workpiece zero point G52.
When G52 is performed, the coordinate values to which the G52
command applies are assigned to the current position. This corresponds
to the definition of the workpiece zero point relative to the current position.
•
Axes which are not programmed using G52 work in the machine coor-
dinate system.
•
Programming G52 produces a G53 when the change occurs. All zero
offsets which are already active are canceled.
•
No further functions may be programmed in a NC-block containing
G50.
•
Coordinate rotation P cannot be programmed in combination with G52.
