Coordinate system
The coordinates entered for the principal axes X and Z are
referenced to the workpiece datum.
The axis designations X and Z describe positions in a two
dimensional coordinate system. As you can see from the figure to
the center right, the position of the tool tip is clearly defined by its
X and Z coordinates.
The control can connect points by linear and circular paths of
traverse (interpolations). Workpiece machining is programmed by
entering the coordinates for a succession of points and connecting
the points by linear or circular paths of traverse.
Like the paths of traverse, you can also describe the complete
contour of a workpiece by defining single points through their
coordinates and connecting them by linear or circular paths of
traverse.
Positions can be programmed to an accuracy of 1 µm (0.001 mm).
This is also the accuracy with which they are displayed.
Absolute coordinates
If the coordinates of a position are referenced to the workpiece
datum, they are referred to as absolute coordinates. Each position
on a workpiece is clearly defined by its absolute coordinates.
Incremental coordinates
Incremental coordinates are always given with respect to the last
programmed position. They specify the distance from the last
active position to the subsequent position. Each position on a
workpiece is clearly defined by its incremental coordinates.
