Use drilling operations to machine simple holes. For more complex holes such as counterbore holes or undercut holes, consider using milling operations.

Drilling operations use a point to point processor to generate tool paths. Several drill Operation Subtypes are available, in which a tool is positioned to geometry, fed into the part, and retracted. You can control parameters such as:

• Depth

• Minimum Clearance Distance

• Dwell

• Break Chip

Drilling operations are associated with drill geometry parent groups.
