The resulting machining marks are, therefore, a helix having a very small pitch, which is equal to the feed. Consequently, the machined surface is always cylindrical.
Great visual feed - back with semitone snap, and actual pitch indicator.

The stability and small dynamic errors could be confirmed by using the method of composite control in which the pitch angular rate of barbette sensed by INS was feed back and compensated in advance.
