All Hole Sets (except for Countersink drilling), require specifying the drill depth type. To define the depth type and references, click Depth in the HoleSet dialog box. The Hole Set Depth dialog box opens. Use one of the following Hole Depth option buttons:
Blind—Drill from the start surface (or Z height) to specified depth. Specify the Start and End surfaces (by either selecting a surface or entering a Z depth). If you select the checkbox next to the Use breakout distance option, the system adds the BREAKOUT_DISTANCE parameter value when calculating depth.
Auto—Depth of drilling is determined automatically, by referencing hole geometry. If the selected axis is associated with several coaxial hole features, the maximum depth will be selected as long as the tool fits inside the hole diameter.
Note: Auto depth is not available for Tap and Ream tools.
Thru All—Drill a through hole, from the retract surface all the way through the workpiece(s) or reference part(s) that the hole intersects. By default, all the reference parts and workpieces are used for depth calculation; you can unselect some of the parts, if desired, or explicitly select parts, by using the Select and Unselect buttons in the Hole Set Depth dialog box. Select All selects all the reference parts and workpieces.
The Tool Depth option buttons, Shoulder and Tip, available for Blind and Auto drilling, determine if the drilling depth will be with reference to the shoulder or the tip of the tool. In the following illustration, the picture on the left shows drilling using Shoulder, and the picture on the right shows drilling using Tip. In both pictures, 1 indicates the outline of the hole being drilled and 2 indicates the outline of the tool at the final drilling depth.
