FeatureCAM uses the following process for creating holes:
- Conducts an analysis of the hole size, type, and attributes to determine what tool to use.
- Picks feeds and speeds based upon the material being drilled.
-
Prepares the site with spot drill and pilot drill operations.
-
Twistdrills to depth.
- Sizes and does counter cutting operations.
-
Taps, or bores/reams if set.
- Holes are output as either canned cycles or computed moves.
There are many variations on this process, particularly with patterns of holes and hole macros. You can edit the basic hole process in these places:
- To edit all Hole features in the current document, use the Drilling tab in Machining Attributes.
- To edit a single Hole feature, use the Tools, Drilling, Strategy, and Misc. tabs in the Feature Properties dialog.
The tooling database also has a large impact on how a hole is drilled, and the feed/speed database helps to determine the feeds and speeds used.
