This tab is available when using Turnmilling toolpaths (machining rotating stock with a rotating endmill).
Use the Mill Speed tab to control the speed of rotation of milling tools when used for turning operations. This tab is only available when a Toolpath type of Turnmilling is selected on the Strategy tab.
Speed
The Speed section is for setting how fast the tool spins. The default units are RPM (revolutions per minute). Optionally select Use SFM (surface feet per minute) to change the units. FeatureCAM uses the Recommended speed value by default. You can optionally enter a different value and the override option is automatically selected. If you want to revert back to the recommended value, deselect override.
