Web drilling enables you to drill holes through two or more plates, separated by a certain distance, with the tool moving with FEED_RATE while drilling a plate, and then making a RAPID motion along the tool axis to position above the next plate.
If you perform Auto or Thru All drilling, the system will determine start and end of drilling for each plate based on the intersection of the hole axes with the parts selected for depth calculation. 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.
If you perform Blind drilling, the Hole Set Depth dialog box contains an extra section at the bottom, Plate Selection, which lists all the plates defined so far, and has the following buttons:
Add—Adds a new plate. Define the Start and End surfaces for a new plate, then click this button. The system adds the plate name to the list in the Defined Plates for Web Drilling box.
Change—Changes the Start and End surfaces for an existing plate. Highlight the plate name in the Defined Plates for Web Drilling list box and respecify the Start and End surfaces for this plate, then click this button.
Delete—Deletes the highlighted plate.
