Feeds and speeds values are calculated automatically for each operation based on FeatureCAM's built-in feed/speed database.
Each feature is automatically broken down into a collection of operations. Feeds and speed settings for each operation are automatically calculated. To view the recommended feed or speed value for an operation, click the operation in the tree view and then click the Feed/Speed tab for turning operations, the F/S tab for milling operations, or the Turn F/S tab for turnmilling operations.
The recommended feed and speed values are extracted from a built-in database in FeatureCAM. The combination of the stock material, the tool material, and the manufacturing operation are used to find the suitable values in the FeatureCAM feed/speed tables.
You can customize this database by changing the values for an existing table or by creating a new table for an additional material. By customizing the database in this way, you are ensuring that FeatureCAM makes future decisions about feed and speed values just as you would.
You can also explicitly set the feed rate or spindle speed for an individual operation, but these changes only affect a single feature in a single part file.
