This check box tells SURFCAM to look for the locations on the surfaces where pilot holes are needed.
The default setting for the box is checked. If the box is not checked, SURFCAM will not look for the needed pilot hole locations. If the box is checked and SURFCAM does not find any needed pilot holes, no action is taken.
If needed pilot hole locations are found, a dialog box is displayed after the Plunge Rough operation is finished.
After you click Yes the 2 Axis Pilot Hole dialog box is displayed. Use this dialog box to set the parameters for the pilot holes.
When the operation is completed, the Pilot Hole operation is put above the Plunge Rough operation in the Operations Manager Toolpath Tree.
Plunge Rough pilot holes can overlap. If pilot holes that overlap are found, select the correct tool to cut the holes that overlap. A rigid tool is needed.
If a Center Drill operation is needed for the Pilot Holes, do that operation in a separate step. Use the 3 Axis Pilot Hole operation. On the Select Operation dialog box that is displayed, select the Plunge Rough operation. On the Pilot Hole Cut Control tab, set the Center Drill parameter to the Yes option. Enter the correct value for Hole Depth.
When the operation is completed, the Center Drill Pilot Hole operation is put above the Plunge Rough operation in the Operations Manager Toolpath Tree. To put the three operations in the correct sequence, put the Center Drill operation above the Pilot hole operation that was done earlier.
