The workpiece preset is not always located in a manner that lets you machine the entire part. Therefore, the control has a function with which you can define a new datum and a tilting operation.
Description of function
- When you select the Datum icon, the control displays the following information in the list view window:
- Distance between the datum that has been set and the workpiece preset
- Orientation of the coordinate system
You can set a workpiece datum and also move it further by entering values directly in the list view window.
The control displays values not equal to 0 in orange.

The datum with the orientation of the coordinate system can be set at the same positions as a preset.
Workpiece preset in the CAD model
If you have set a workpiece datum, the control displays the Datum icon in the menu bar with a yellow area.
Set the workpiece preset or workpiece datum and align the coordinate system
The datum and its optional orientation can be inserted as NC block or comments in the NC program by using the TRANS DATUM AXIS function for the datum and the PLANE SPATIAL function for the orientation.
If you define only one datum and its orientation, then the control inserts the functions in the NC program as an NC block.

If you additionally select contours or points, then the control inserts the functions in the NC program as comments.
