FeatureCAM follows this general process to create a Thread feature:
- Determines what tool to use.
- Picks feeds and speeds based on the material being machined.
To view the recommended speed value for a threading operation, click the operation in the tree view and select the Feed/speed tab. The recommended speeds are derived from the Thread column of the turning feed/speed tables. Feed values are determined by the canned cycle on the machine tool.
- Optionally creates a Rough and/or Finish pass to turn the part down to the diameter of the thread. The creation of these operations is controlled by the Rough and Finish options on the Strategy page. See How a turn feature is manufactured for more details.
- Optionally generates a roughing pass for the relief groove. The existence of this operation is controlled by the Relief groove option on the Strategy page.
- Generates a Thread pass.
