To Apply Hole Strategies
You can specify which drilling method to use for each hole by selecting from a list of preset Hole Strategies.
1. Click View > Apply Drilling Method.
2. Select the hole(s) in the Auto-Drilling table. To select one or more holes, click in the appropriate row(s). To select a range of holes, select the first hole in the range, then hold down the SHIFT key and select the last hole in the range. Once you select a hole, its row is highlighted. To unselect a single hole and retain the rest of selections, click again in the highlighted row.
3. Select the Hole Strategy you want to apply to these holes. The existing Hole Strategies are listed in the right pane of the Auto-Drilling dialog box. You can browse through the directory structure to search for the Hole Strategies. By default, the search starts in the directory specified by using the configuration option autodrill_udf_dir <pathname>, or, if not specified, in your working directory.
4. Select one of the depth options on the Hole Strategies tab:
From Table—The drill depth is defined by the Depth parameter in the Auto-Drilling table. If you select this option, the Hole Strategy will have the <T> prefix when it is listed in the Hole Style field of the Auto-Drilling table.
From Param—The drill depth is defined either by the table or by the UDF NC sequence, depending on the DEPTH_BY_TABLE parameter value. This feature parameter of type Yes or No must be assigned to the UDF NC sequence before you create the UDF. If the parameter is set to Yes, then the drill depth is defined by the Depth parameter in the Auto-Drilling table; if it is No, then the drill depth is defined by the UDF NC sequence. If you select this option, the Hole Strategy will have the <P> prefix when it is listed in the Hole Style field of the Auto-Drilling table.
From Seq—The drill depth is defined by the UDF NC sequence. If you select this option, the Hole Strategy will have the <S> prefix when it is listed in the Hole Style field of the Auto-Drilling table.
5. Click <<to apply the selected strategy to the highlighted holes.
The system displays the name of the Hole Strategy with the appropriate depth prefix in the Hole Style field of the Auto-Drilling table and changes the Status field from Incomplete to Complete.
6. To remove a previously applied Hole Strategy, select the hole(s) in the Auto-Drilling table and click Remove.
7. To exit the Auto-Drilling dialog box and create the appropriate Holemaking NC sequences, click OK.
