Performing lathe type operations on a milling machine using a HA5C indexer. A brass bar is chamfered then knurled then cut off. The knurling tool is a custom made single knurl. Spindle orientation is used to make sure the knurl is properly oriented with the bar. An 1/8" end mill is used to spiral cut the knurled blank from the bar.

Not sure how Bridgeport TC works. On the Haas, the indexer is just another axis. In this case, it is the A axis. There is a parameter on the mill that you have to set that indicates the diameter of the bar you are using. All axis commands are in degrees, however, feed rates are still in inches/minute based on the diameter you enter. OK, so if you make a G01 F10.0 Z-0.25 A360.0 then that will make a coordinated spiral into the bar. Similar command in X axis will cut a spiral across the bar
