You control machine-level drill/mill in the machine-level Drill/Mill Options dialog.
Select the strategies that you want to enable. The options are:
- Drill full diameter
- Rough with Drill, Finish with Bore
- Rough with Drill, Finish with Ream
- Rough with Endmill, Finish with Bore

- Finish Bottom
- Helical Side Finish — Select this option to use a continuous spiral for the Finish pass. Enter a Pitch to control the tightness of the spiral.
-
Rough with Endmill to full diameter — This option lets
FeatureCAM rough to the final hole diameter without having a finish pass.
- Use hole milling canned cycle if available ( ) — For machines that support hole/bore milling, such as Heidenhain Cycle 208, Siemens POCKET4, Fagor G88, and Haas G12/13. The hole milling canned cycle is posted using the hole milling format in XBUILD. If you enter a G code, for example G208, for the Hole Milling cycle in the NC Codes dialog in XBUILD, that code displays in the brackets after this attribute name, for example Use hole milling canned cycle if available (G208).
If you select more than one strategy, FeatureCAM works down the strategy list in the dialog until it finds a strategy that can complete the hole.
