Stepping angle

Q247 (incremental value): Angle

between two machining operations on a pitch circle.
If you enter an angle step of 0, the TNC will calculate
the angle step from the starting and stopping angles
and the number of pattern repetitions. If you enter a
value other than 0, the TNC will not take the stopping
angle into account. The sign for the angle step
determines the working direction (– = clockwise).
