To Select a Coordinate System and Retract Plane
You must specify the coordinate system (Program Zero) and retract plane to be used for Auto Drilling. The system automatically finds all the holes with the axes parallel to the z-axis of the specified coordinate system and lists them in the Auto-Drilling table. You can further filter these holes, if desired, and then apply drilling methods to some or all of them.
1. Click View > Select Csys.
The Auto-Drilling dialog box displays the names of the currently selected coordinate system and retract plane in text boxes labeled Nc Sequence Program Zero and Nc Sequence Retract Plane, respectively. There is a Select icon next to each text box. There are also three buttons below the text boxes: Apply, Default, and Previous. The list box on the right contains all the previously specified combinations of the Program zero coordinate system and retract plane.
2. To change the coordinate system, click the Select icon and select a coordinate system on the screen (or create a new one).
3. To change the retract plane, click the Select icon use the following options in the Retract Selection dialog box:
◦ Select—Select a datum plane. It must be normal to the z-axis of the currently selected coordinate system.
◦ Along Z Axis—Type the offset value along the z-axis of the currently selected coordinate system.
4. You can also select an existing combination of the Program Zero coordinate system and retract plane from the list box on the right.
5. Click one of the three buttons below the text boxes:
◦ Apply—Accept the currently selected combination of the coordinate system and retract plane.
◦ Default—Use the default coordinate system and retract plane.
◦ Previous—Ignore the current selections and return to the previous Auto-Drilling table.
